Chordal force distribution determines systolic mitral leaflet configuration and severity of functional mitral regurgitation. (1/2148)

OBJECTIVES: The purpose of this study was to investigate the impact of the chordae tendineae force distribution on systolic mitral leaflet geometry and mitral valve competence in vitro. BACKGROUND: Functional mitral regurgitation is caused by changes in several elements of the valve apparatus. Interaction among these have to comply with the chordal force distribution defined by the chordal coapting forces (F(c)) created by the transmitral pressure difference, which close the leaflets and the chordal tethering forces (FT) pulling the leaflets apart. METHODS: Porcine mitral valves (n = 5) were mounted in a left ventricular model where leading edge chordal forces measured by dedicated miniature force transducers were controlled by changing left ventricular pressure and papillary muscle position. Chordae geometry and occlusional leaflet area (OLA) needed to cover the leaflet orifice for a given leaflet configuration were determined by two-dimensional echo and reconstructed three-dimensionally. Occlusional leaflet area was used as expression for incomplete leaflet coaptation. Regurgitant fraction (RF) was measured with an electromagnetic flowmeter. RESULTS: Mixed procedure statistics revealed a linear correlation between the sum of the chordal net forces, sigma[Fc - FT]S, and OLA with regression coefficient (minimum - maximum) beta = -115 to -65 [mm2/N]; p < 0.001 and RF (beta = -0.06 to -0.01 [%/N]; p < 0.001). Increasing FT by papillary muscle malalignment restricted leaflet mobility, resulting in a tented leaflet configuration due to an apical and posterior shift of the coaptation line. Anterior leaflet coapting forces increased due to mitral leaflet remodeling, which generated a nonuniform regurgitant orifice area. CONCLUSIONS: Altered chordal force distribution caused functional mitral regurgitation based on tented leaflet configuration as observed clinically.  (+info)

Changes in porcine transmitral flow velocity pattern and its diastolic determinants during partial coronary occlusion. (2/2148)

OBJECTIVES: To define the mechanical determinants of transmitral flow and the effect of heart rate during regional ischemia. BACKGROUND: Myocardial ischemia changes the transmitral flow velocity pattern due to disease-induced changes in the heart's diastolic properties. METHODS: Regional ischemia was produced in 12 pigs by partially occluding the left anterior descending coronary artery until segment-length shortening in the ischemic region fell by 20%. Transmitral flow velocity patterns and their determinants were measured under two conditions, baseline and ischemia, at two heart rates, 70 and 90 beats/min. RESULTS: Regional ischemia had a significant effect on two determinants of filling: relaxation, which was slower, and chamber stiffness, which increased. These changes were associated with reduced contractility and increased myocardial stiffness, resulting in an early transmitral flow pattern that was flatter and narrower, but no change in the late flow pattern. Moderate increases in heart rate accelerated relaxation and decreased atrioventricular pressure gradient but had no effect on contractility or myocardial or chamber stiffness, resulting in an early transmitral flow pattern that was flatter and narrower and an increased late flow velocity. CONCLUSIONS: This model of regional ischemia leads to a flatter and narrower early transmitral flow velocity pattern and no change in late flow due to a combination of slowed left ventricular relaxation and increased chamber stiffness. Reflex increases in heart rate that accompany ischemia tend to mask this effect.  (+info)

Effects of permanent dual-chamber pacing on mitral regurgitation in hypertrophic obstructive cardiomyopathy. (3/2148)

AIMS: To assess the effects of chronic dual-chamber pacing on mitral regurgitation in hypertrophic obstructive cardiomyopathy. METHODS AND RESULTS: Twenty-three patients with hypertrophic obstructive cardiomyopathy and mitral regurgitation. treated with DDD pacing for 16 +/- 14 months, were included in the study. Mitral regurgitation was assessed by Doppler-echocardiography using semi-quantitative analysis (grades I-IV) and by measuring the maximum regurgitant jet area/left atrial area ratio. At the end of follow-up, DDD pacing reduced the outflow gradient from 93 +/- 37 mmHg to 31 +/- 30 mmHg (P<0.0001). Nine of the 14 patients who initially had > or =grade II mitral regurgitation improved by at least one grade, two of them exhibiting dramatic improvement (from grade IV and III to grade I). The regurgitant jet area/left atrial area ratio was reduced with DDD pacing from 20 +/- 13% to 11 +/- 6% (P<0.0001). Patients who had significant mitral regurgitation despite pacing were those whose outflow gradient remained high or those with mitral valve organic abnormalities (mitral annulus calcification or mitral valve prolapse). In the absence of organic abnormalities other than leaflet elongation, there was a significant correlation between the gradient value achieved with DDD pacing and the extent of mitral regurgitation (P<0.05). CONCLUSION: In the absence of organic mitral valve abnormalities, DDD pacing reduces in parallel mitral regurgitation and left ventricular outflow gradient. In such patients therefore, significant mitral regurgitation is not a contraindication to pacing.  (+info)

Perivalvular abscesses associated with endocarditis; clinical features and prognostic factors of overall survival in a series of 233 cases. Perivalvular Abscesses French Multicentre Study. (4/2148)

AIMS: The purposes of this study were to determine the clinical features and to identify prognostic factors of abscesses associated with infective endocarditis. METHODS AND RESULTS: During a 5-year period from January 1989, 233 patients with perivalvular abscesses associated with infective endocarditis were enrolled in a retrospective multicentre study. Of the patients, 213 received medical surgical therapy and 20 medical therapy alone. No causative microorganism could be identified in 31% of cases. Sensitivity for the detection of abscesses was 36 and 80%, respectively using transthoracic and transoesophageal echocardiography. Surgical treatment consisted of primary suture of the abscess (38%), insertion of a felt aortic or mitral ring using Teflon or pericardium (42%), or debridment of the abscess cavity (20%). The 1 month operative mortality was 16%. Actuarial rates for overall survival at 3 and 27 months in operated patients were 75 +/- 10% and 59 +/- 11%, respectively. Increasing patient age, staphylococcal infection, and fistulization of the abscess were found to be independent risk factors in both 1 month and overall operative mortality. Renal failure was a risk factor predictive of operative mortality at 1 month, whereas uncontrolled infection and circumferential abscess were regarded as risk factors predictive of overall operative mortality. CONCLUSION: The data determined prognostic factors of abscesses associated with infective endocarditis.  (+info)

Intraoperative left ventricular perforation with false aneurysm formation. (5/2148)

Two cases of perforation of the left ventricle during mitral valve replacement are described. In the first case there was perforation at the site of papillary muscle excision and this was recognized and successfully treated. However, a true ventricular aneurysm developed at the repair site. One month after operation rupture of the left ventricle occurred at a second and separate site on the posterior aspect of the atrioventricular ring. This resulted in a false aneurysm which produced a pansystolic murmur mimicking mitral regurgitation. Both the true and the false aneurysm were successfully repaired. In the second case perforation occurred on the posterior aspect of the atrioventricular ring and was successfully repaired. However, a false ventricular aneurysm developed and ruptured into the left atrium producing severe, but silent, mitral regurgitation. This was recognized and successfully repaired. The implications of these cases are discussed.  (+info)

Echocardiographic diagnosis of large fungal verruca attached to mitral valve. (6/2148)

In a patient with endocarditis due to Candida tropicalis echocardiograms from mitral valve vegetations were found to mimic the typical pattern of a left atrial myxoma. A mass was shown occupying the mitral orifice posterior to the anterior mitral leaflet; densities also appeared in the left atrium. Though these echocardiographic findings were consistent with the diagnosis of a left atrial myxoma, there were other distinctive differential diagnostic features. Other diagnostic possibilities must, therefore, be considered in the interpretation of echocardiograms which suggest left atrial tumour.  (+info)

Long-term clinical and echocardiographic follow-up after percutaneous mitral valvuloplasty with the Inoue balloon. (7/2148)

BACKGROUND: The objective of this study was to assess the long-term clinical outcome and valvular changes (area and regurgitation) after percutaneous mitral valvuloplasty (PMV). METHODS AND RESULTS: After PMV, 561 patients were followed up for 39 (+/-23) months and clinical/echocardiographic data obtained yearly. Kaplan-Meier and Cox regression analyses were performed to estimate event-free survival, its predictors, and the relative risks of several patient subgroups. There were several nonexclusive events: 19 (3.3%) cardiac deaths, 55 (9.8%) mitral replacements, 6 (1%) repeated PMVs, 56 (10%) cases of restenosis, and 108 (19%) cases of clinical impairment. Survival free of major events (cardiac death, mitral surgery, repeat PMV, or functional impairment) was 69% at 7 years, ranging from 88% to 40% in different subgroups of patients. Wilkins score was the best preprocedural predictor of mitral opening, but the procedural result (mitral area and regurgitation) was the only independent predictor of major event-free survival. Mitral area loss, though mild [0.13 (+/-0.21)cm2], increased with time and was >/=0.3 cm2 in 12%, 22%, and 27% of patients at 3, 5, and 7 years, respectively. Regurgitation did not progress in 81% of patients, and when it occurred it was usually by 1 grade. CONCLUSIONS: Seven years after PMV, more than two thirds of patients were in good clinical condition and free of any major event. The procedural result was the main determinant of long-term outcome, although a high score had also negative implications. Mitral area decreased progressively over time, whereas regurgitation did not tend to progress.  (+info)

Mobile echoes on prosthetic valves are not reproducible. Results and clinical implications of a multicentre study. (8/2148)

AIMS: To test the hypothesis that inter-observer variability accounts for the wide variation in reported prevalences of fibrin strands on prosthetic heart valves and to develop criteria for their identification and reporting. METHODS AND RESULTS: A videotape with 30 sequences of prosthetic heart valves imaged by transoesophageal echocardiography and showing abnormalities such as strands, microbubbles, and spontaneous echocardiographic contrast, was assessed in 13 European and three American centres. There were three duplicated examples, unbeknown to the observers. Definitions and reported prevalence rates of the abnormalities were analysed, and inter- and intra-observer agreement estimated with the kappa statistic. Mobile echoes were identified in 40 to 80% of the sequences on the tape. The reported prevalence of mobile echoes correlated with the time spent reporting the tape. There was moderate inter-observer agreement for the identification of any mobile echoes (kappa = 0.38), but no agreement for their labelling (kappa = 0.22), in spite of similar definitions. Intra-observer reproducibility was good (agreement in 76% of the reduplicated sequences). CONCLUSIONS: The true prevalence and potential significance of mobile echoes on prosthetic heart valves cannot be assessed unless inter-observer consensus on echocardiographic criteria for identifying such echoes is reached.  (+info)

Double orifice mitral valve (DOMV) without mitral regurgitation or mitral stenosis are asymptomatic. Physical findings may only exist if mitral regurgitation or mitral stenosis are present.. The severity of symptoms depends on the degree of left atrial hypertension. Dyspnea, nocturnal cough, and tachypnea occur, related to pulmonary venous congestion and increased lung stiffness. Frequent respiratory infections and wheezing occur, secondary to pulmonary congestion, increased fluid exudation, and airway narrowing. Poor feeding, failure to thrive, fatigue and sweating occur because of heart failure and reduced cardiac output. On occasion, a child with double orifice mitral valve presents with acute pulmonary edema or generalized edema. Hemoptysis and syncope can occur in older patients with double orifice mitral valve.. Double orifice mitral valve is detected in one of 3 ways. As an associated lesion with other congenital heart defects, especially in the presence of atrioventricular (AV) septal ...
BURCHELL, Richard K. and SCHOEMAN, Johan. Advances in the understanding of the pathogenesis, progression and diagnosis of myxomatous mitral valve disease in dogs. J. S. Afr. Vet. Assoc. [online]. 2014, vol.85, n.1, pp.01-05. ISSN 2224-9435.. A number of key questions remain unanswered in the pathogenesis of myxomatous mitral valve disease (MMVD). As MMVD typically afflicts small-breed dogs, a genetic basis has been implied. In addition, the fact that not all dogs within a risk group develop MMVD is still unexplained. Research into the pathogenesis of MMVD typically falls under three categorical divisions, namely genetic factors, mechanical factors of the valve and systemic factors. Genetic studies have implicated certain loci in the pathogenesis of MMVD. Of particular interest is the insulin-like growth factor (IGF)-1 locus, as IGF-1 is also associated with growth. The mechanical structure and function of the mitral valve have also received much attention in recent years. What has emerged is the ...
BURCHELL, Richard K. y SCHOEMAN, Johan. Medical management of myxomatous mitral valve disease: An evidence-based veterinary medicine approach. J. S. Afr. Vet. Assoc. [online]. 2014, vol.85, n.1, pp.01-07. ISSN 2224-9435. http://dx.doi.org/10.4102/jsava.v85i1.1095.. Myxomatous mitral valve disease (MMVD) is the most common heart disease of dogs. The current management of MMVD in dogs is mostly pharmacological, and the recommendations for treatment are based on a number of veterinary studies. Notwithstanding the current consensus regarding the medical management of MMVD, there remains active debate as to which drugs are the most effective. In order to understand how recommendations are constructed in the pharmacological management of diseases, the veterinarian needs to understand the concept of evidence-based veterinary medicine, and how the findings of these studies can be applied in their own practices. This review summarises the current veterinary literature and explains how the consensus ...
Your blood is supposed to follow a one-way path through your heart. It flows in through the top chamber (the left atrium), down to the bottom chamber (the left ventricle), and then out to your body. Your mitral valve separates these two chambers and keeps the blood from flowing backward. In mitral valve regurgitation, your mitral valve does not work as it should and allows blood to flow backward into your upper heart chamber.. Mitral valve regurgitation can happen suddenly (acute) or, more commonly, gradually over time (chronic). Acute mitral valve regurgitation is often caused by damage to the heart, perhaps from a heart attack or a heart infection called endocarditis. There are many possible reasons you can develop chronic mitral valve regurgitation, including mitral valve prolapse, rheumatic heart disease and untreated high blood pressure. If you have mitral valve regurgitation, you may notice that you feel very tired and that you have a hard time catching your breath when you exercise or ...

A catheter is inserted along the venous system of the patient through the atrium into the mitral valve. A suction tip grasps the leaflets of the mitral valve to immobilize and juxtapose the leaflets at a point simulating a stitch, and the mitral valve is again observed to confirm that fastening at that point will repair the prolapse or other defect. The mitral valve leaflets are then via a fastening such as a staple or shape memory rivet. The fastener may be inserted by a stapling assembly in the venous catheter tip, or by a separate stapler that is inserted along an arterial path from the opposite direction and guided along a transcardiac rail to the immobilized point. Upon completion of the repair process, the mitral valve is once again visualized by transesophageal

However, prosthetic annuloplasty has some drawbacks and potential hazards. Suture annuloplasty theoretically is able to preserve annular leaflet dynamics and left ventricular performance, but experience is limited. The aim of the study was to review the early and long-term outcome of the posterior double-suture annuloplasty (DSA) technique for degenerative mitral valve repair. Methods From January 2002 to December 2008, 400 patients underwent primary mitral valve repair for degenerative disease ...
It was a very good discussion on minimally invasive Mitral valve surgery. Everyone is talking about a right sided mini thoracotomy. For the Mitral valve, we forget that the Mitral valve is a left sided structure and the Left Atrium is a posterior structure. We, particularly in India have been used to approaching the Mitral through the left side for a Closed Mitral Valvotomy. Now we can accomplish arterial and venous return through excellent groin cannulation available today. Since most of the Mitral valve patients are relatively young, the concern for atherosclerosis emboli should be minimal. When one does the procedure through the left side, the Mitral valve is closer to the surgeon and the surgery can be accomplished through routine instruments. One does not need knot tiers and knot pushers. From the right side, the Mitral valve is at a fair distance from the incision and one loses the tactile sensation. Advantages of approaching the Mitral valve through the left side are 1. Easy and secure ...

The mitral valve lies between the left atrium and the left ventricle and has two leaflets, the anterior and the posterior. In the figures below, the anterior leaflet is colored green and the posterior leaflet is colored blue. The corresponding video clips show the motion of the valve through the cardiac cycle, but the leaflets are not colored. The images in the left column show the mitral valve directly visualized from the left ventricle, where the chordae tendinae of the subvalvular apparatus can be appreciated. The middle images are taken using transthoracic echocardiography in a 2 chamber, long axis view of the mitral valve. The images on the right are taken of the anterior and posterior leaflets in a short axis view of the heart taken at the level of the mitral valve annulus using transthoracic echocardiography. Applications such as color flow echocardiography allow for the visualization of flow through the mitral valve. Other anatomical features of the mitral valve that can be visualized ...
IMR continues to be a clinical challenge, and the best surgical treatment for this ever-increasing patient population remains to be defined. Alfieri edge-to-edge mitral repair along with mitral ring annuloplasty partially eliminates ischemic and functional mitral regurgitation.10,12 However, no large series of patients with IMR treated with this technique has been reported, and the efficacy of Alfieri repair without ring annuloplasty is unknown. This acute ovine experiment revealed that the Alfieri repair did not prevent acute IMR. Furthermore, it did not alter the annular, subvalvular, and leaflet geometric distortions associated with acute ischemia.. Acute posterolateral ischemia in sheep results in annular dilatation and larger SL annular diameter,18 similar to that reported here. However, the mitral CC diameter increase, has not been observed previously and may be because of the acute, open-chest nature of this experiment. Interestingly, the annular geometric changes during ischemia did not ...
TY - JOUR. T1 - Thoracoscopic Versus Open Mitral Valve Repair. T2 - A Propensity Score Analysis of Early Outcomes. AU - Suri, Rakesh M.. AU - Schaff, Hartzell V.. AU - Meyer, Steven R.. AU - Hargrove, W. Clark. PY - 2009/10/1. Y1 - 2009/10/1. N2 - Background: The very low risk of mitral valve repair performed through median sternotomy must be reproducible when using a port-access approach to justify early repair employing minimally invasive platforms. We compared the outcomes of mitral valve repair performed through port access using thoracoscopic assistance (port) versus median sternotomy (open). Methods: The early results after mitral valve repair performed by two different surgeons at two separate institutions were analyzed. Between January 1999 and December 2006, isolated mitral valve repair was performed with a port approach in 350 patients and an open approach in 365 patients. Results: The mean age was similar between the two groups; however, port patients were more frequently female (148 ...
A device effects the mitral valve annulus geometry of a heart. The device includes a first anchor configured to be positioned within and anchored to the coronary sinus of the heart adjacent the mitral valve annulus within the heart and a second anchor configured to be positioned within the coronary sinus of the heart proximal to the first anchor and adjacent the mitral valve annulus within the heart. The second anchor, when deployed, anchors against distal movement and is moveable in a proximal direction. The device further includes a connecting member having a fixed length permanently attached to the first and second anchors. As a result, when the first and second anchors are within the coronary sinus with the first anchor anchored in the coronary sinus, the second anchor may be displaced proximally to effect the geometry of the mitral valve annulus and released to maintain the effect on the mitral valve geometry.
12 patients who had atrial flutter without clinical, echocardiographic or angiographic evidence of aortic insufficiency were studied with simultaneous echo- and phonocardiograms. In patients with high-grade atrioventricular (AV) block, the mitral valve opened and closed with each flutter wave. Of seven patients, two had persistent and five had intermittent early mitral valve closure before QRS inscription. In five patients (three with 2:1 AV block) the mitral valve closed on time. In one patient with a mitral valve prosthesis, echocardiography and cinefluorography demonstrated closure during mid-diastole, with reopening in late diastole after a flutter wave. Final valve closure occurred before the onset of the QRS, and each closure was associated with a click. Simultaneous phonocardiographic analysis in these patients demonstrated that the first heart sound intensity was inversely related to the degree of mitral valve preclosure. This relationship was independent of the length of the RR ...
The paper by Feldman et al. (1) in this issue of the Journalis the first published report about a new percutaneous mitral valve technology, the edge-to-edge Evalve clip (Evalve Inc., Menlo Park, California). This is an important step into a new era of catheter-based valve procedures and one that will be compared and contrasted with the ongoing excellent surgical results obtained with mitral valve repair of the myxomatous regurgitant mitral valve. The investigators, who are among the leading cardiac interventionalists in the country, have performed a carefully thought out phase I U.S. Food and Drug Administration safety trial of 27 low-risk patients with myxomatous valve disease, a group of patients for whom surgical repair of the mitral valve is safe and effective. They have clearly documented the safety of this procedure, and have also documented that there is a significant learning curve as it relates to fluoroscopy time, echocardiography time, and anesthesia time. The investigators have been ...
Background: Mitral valve repair (MVRr) has become the mainstay of surgical treatment for mitral valvular regurgitation. Evaluation of MVRr by intraoperative transesophageal echocardiography (IOE) has been routinely employed to guide the operation. While the main objective of IOE is to assess for residual mitral regurgitation, it is also important to exclude significant mitral stenosis. Utilisation of pressure half-time (PHT) to estimate mitral valve area (MVA) has been shown to be reliable in normal clinical situations. However, in MVRr, the accuracy of MVA calculation by PHT needs to be ascertained. Methods and results: Data from IOE and post-MVRr transthoracic echocardiography (TTE) from the year 1998 to 2002 were analysed and when required, offline PHT measurements were made. The mean time interval between the two echocardiographic examinations was 10.6 (1 to 56) weeks. In our 36 cases, the IOE MVA was found to be 2.1 ± 0.5 cm 2, with the corresponding TTE MVA to be 2.7 ± 1.0 cm 2. MVA by ...
Mitral valve surgery can repair or replace your hearts mitral valve. The new valve may be mechanical or made of animal tissue, often from a pig. Your doctor will talk with you before surgery about which type of valve is best for you.. The mitral valve opens and closes to keep blood flowing in the proper direction through your heart. When the mitral valve does not close properly (mitral valve regurgitation) or is very tight and narrow (mitral valve stenosis), blood does not flow through the heart the right way.. You will be asleep during the surgery. The doctor will make a cut (incision) in the skin over your breastbone (sternum). Then the doctor will cut through your sternum to reach your heart.. The doctor will connect you to a heart-lung bypass machine, which is used to add oxygen to your blood and move the blood through your body. This machine will allow the doctor to stop your heartbeat while he or she works on your heart.. While your heartbeat is stopped, the doctor will repair or replace ...
It can be reasonably argued that the very dawn of cardiac surgery began with a mitral valve repair. On May 20, 1923, Dr Elliot Carr Cutler (Fig. 35-1) performed the worlds first successful mitral valve repair at the Peter Bent Brigham Hospital in Boston, Massachusetts.1 Dr Cutler carried out a transventricular mitral valve commissurotomy with a neurosurgical tenotomy knife on a critically ill 12-year-old girl. His choice of instrument was likely influenced by Dr Harvey Cushing who was surgeon-in-chief at the time. A new era in surgery was introduced as well as the reality of mitral valve repair.2 Cutler had worked assiduously on this problem in the Surgical Research Laboratories of Harvard Medical School before turning his attention to this critically ill patient. Subsequent attempts at this operation using a device to cut out a segment of the diseased mitral valve resulted in several deaths from massive mitral regurgitation and Cutler eventually abandoned the procedure.3 Of Cutlers ...
The purpose of this study is to determine whether the addition of surgical ablation to planned mitral valve surgery for patients with persistent or longstanding persistent AF (within 6 months prior to randomization) reduces the incidence of postoperative heart arrhythmia compared to mitral valve repair with medication therapy alone. This is a randomized, multi-center trial which will enroll 260 subjects who will be randomized in a 1:1 fashion to: (a) mitral valve surgery plus surgical ablation or (b) mitral valve surgery without ablation (control group). All patients will undergo ligation or excision of the left atrial appendage. Patients assigned to the ablation group will be further randomized (1:1) to one of two lesion sets: (1) pulmonary vein isolation only or (2) biatrial Maze lesions. The target population for this trial consists of adult patients with mitral valve disease requiring surgical intervention and persistent or longstanding persistent atrial fibrillation. All patients who meet ...

AU - Minzioni, G.. AU - Vigano, M.. PY - 1993. Y1 - 1993. N2 - Ablation of atrial fibrillation secondary to mitral valve disease is frequently impossible after isolated mitral valve surgery. In order to improve sinus rhythm recovery in such patients, patients with rheumatic mitral valve disease and chronic atrial fibrillation underwent surgical electrophysiological isolation of the left atrium at the time of surgery. The left atrium is left free to fibrillate, beat or stand still, while the right atrium recovers its sinus activation and warrants a regular ventricular rate. Apart from this advantage, we tested the hypothesis that the recovery of right atrial booster function could significantly improve cardiac output. From May 1989 to July 1993 184 patients with mitral with or without other valve disease ...
Our study shows that: 1) the mitral leaflet coaptation decreased proportionally in patients with FMR related to the bilateral PM displacement, despite increased total leaflet area to compensate for the increased mitral annular area and mitral leaflet tethering; 2) annular area was significantly smaller and leaflet-to-annular area ratio was significantly larger in patients with global LV remodeling who have nonsignificant FMR compared with the patients with significant FMR; and 3) the indexes of coaptation were related to MR severity.. FMR is produced by a complex combination of pathophysiological processes where distorted and spherical LV geometry leads to tethering of the chordae and therefore incomplete leaflet coaptation (8,10,21). In this condition, patients with mitral leaflet tethering have been shown to have larger mitral leaflet area than the control subjects (10). Similarly, Dal-Bianco et al. (22) demonstrated that mechanical stresses imposed by PM tethering increased MV leaflet area ...
May 2, 2017 /Press Release/ -- Patients can maximize chances of high-quality mitral valve repair through referral to surgeons with large annual repair rates. Surgeons who perform more than 25 mitral valve operations a year are more likely to perform repairs that are durable, and their patients are more likely to be alive a year after the operation, than when operations are performed by lower-volume surgeons, an Icahn School of Medicine at Mount Sinai study has found.. The results of the study will be presented at the American Association for Thoracic Surgery Centennial meeting on Tuesday, May 2, in Boston and published online simultaneously in the Journal of the American College of Cardiology. The study is the first to highlight that patients operated on by higher volume mitral surgeons experienced lower one year mortality and rates of reoperations compared to those operated by low volume mitral surgeons.. Mitral valve repair is the recommended treatment for patients with severe degenerative ...
CAD occurs when the arteries that supply blood to the heart become blocked as a result of plaque buildup. In severe cases, CAD can cause chest pain, shortness of breath, and heart attack. CABG is one treatment option for people with CAD. During a CABG procedure, a healthy artery or vein from another part of the body is connected to the blocked coronary artery. Blood flow is then routed around the blockage to the heart.. After a heart attack, some people may have a leak in the mitral valve of the heart. This condition is known as ischemic mitral regurgitation (IMR) and is associated with poor health outcomes, including worsening heart failure. In people with severe mitral valve leakage, the CABG procedure and a mitral valve repair procedure are routinely performed together; however, in people with only moderate valve leakage, there is no consensus in the medical community as to whether the mitral valve repair procedure is beneficial at the time of CABG. The purpose of this study is to determine ...
The normal mitral valve permits one-way blood flow from the left atrium to the left ventricle in an efficient, nearly frictionless fashion.1 Although even a normal competent valve may allow a trivial amount of reversed flow, more than a trace of mitral regurgitation is considered pathologic.2 Mild-to-moderate mitral regurgitation is tolerated indefinitely as long as it does not worsen. However, severe mitral regurgitation causes left ventricular remodeling reduced forward cardiac output, neurohumoral activation, left ventricular damage, heart failure, and ultimately death.3 The natural history of mitral regurgitation depends intimately on its etiology, the severity of left ventricular volume overload as well as its contractile performance, and the appearance of overlapping clinical conditions secondary to reversal flow, such as atrial fibrillation and pulmonary hypertension.4 In this setting, myxomatous degeneration of the mitral valve, a very common pathologic substrate of mitral valve ...

Mitral valve replacement in the presence of severe annular calcification is a technical challenge. A 47-year-old lady who had undergone mitral and aortic valve replacement for rheumatic disease 27 years before presented with dyspnea. At reoperation, extensive mitral annular calcification was hindering the disc motion of the Starr-Edwards mitral prosthesis. The old prosthesis was removed and a St Jude Medical mechanical valve was implanted after thorough annular debridement. Postoperatively the patient developed paravalvular leak and hemolytic anemia, subsequently undergoing reoperation three days later. The mitral valve was replaced with an Edwards MIRA valve, with a bulkier sewing cuff, after more aggressive annular debridement. Although initially there was no paravalvular leak, it recurred five days later. The patient also developed a small cerebral hemorrhage. As the paravalvular leak and hemolytic anemia gradually worsened, the patient underwent reoperation 14 days later. A Carpentier-Edwards
Patients with myelodysplastic syndrome (MDS) most commonly have refractory anemia accompanied by various degrees of granulocytopenia and thrombocytopenia. At the time of cardiac surgery, both major infections and bleeding are severe complications in patients with pancytopenia due to MDS. However, there were very few patients with MDS who had undergone open-heart surgery. We reported a case of mitral valve replacement in a patient with MDS. A 68-year-old man with valvular heart disease and MDS, with a platelet count of 1.9 ~104/mm3, underwent successful mitral valve replacement. The mitral valve was replaced by an SJM25A prosthesis after resection of left atrial thrombosis using cardiopulmonary bypass. Platelets were transfused after the bypass. Perioperative hemorrhage was moderate and postoperative course was uneventful. We evaluated platelet function by Sonoclot coagulation and a platelet function analyzer. We did not need a large amount of transfusion of red blood cells and platelets, and ...
Since reduction annuloplasty alone for ischemic mitral regurgitation (MR) cannot prevent late recurrence of MR or improve survival for those with left ventricular (LV) dysfunction, and the surgical approach to this etiology is still controversial, we conducted a study to assess the efficacy of the additional papillary muscle approximation (PMA) procedure for ischemic MR by comparing the different subtypes of PMA. We studied 45 patients who underwent mitral annuloplasty and papillary muscle approximation (PMA) for ischemic MR between 2003 and 2012. Papillary muscles were approximated entirely (cPMA: complete PMA, n = 32) through an LV incision or partially from the tips to mid-parts (iPMA: incomplete PMA, n = 13) through the mitral and aortic valves. Twenty-three patients with cPMA also underwent LV plasty (LVP). We assessed the outcomes after PMA by comparing cPMA and iPMA. The baseline MR grade, NYHA class, LV end-diastolic diameter, and LV ejection fraction (LVEF) were 2.8 ± 1.0, 3.2 ± 0.6, 67 ± 6
Methods and results Consecutive patients treated with MitraClip from October 2008 to December 2015 were analysed. Primary outcomes of interest were cardiovascular and non-cardiovascular mortality, rehospitalisation for heart failure and major adverse events at 30 days and 90 days. A total of 269 patients were included. Of these, 115 patients were early discharged (ED group). Rates of ED increased from 25.9% for the biennium 2008-2009 to 59.1% in 2014-2015 (p,0.001 for trend). In a penalised logistic regression model, male gender (OR=2.13, 95% CI 1.17 to 3.95) and procedural year (OR=2.13, 95% CI 1.51 to 3.11) were associated with higher probability of ED. Conversely, atrial fibrillation (OR=0.48, 95% CI 0.27 to 0.85), any Mitral Valve Academic Research Consortium bleeding (OR=0.07, 95% CI 0.01 to 0.60), log-transformed N-terminal pro-brain natriuretic peptide levels (OR=0.79, 95% CI 0.63 to 0.99) and postimplant MR grade (OR=0.60, 95% CI 0.37 to 0.94) conferred a lower likelihood of ED.

A minimally invasive mitral valve replacement is a procedure to replace a poorly working mitral valve with an artificial valve. The mitral valve helps blood flow through the heart and out to the body. Your doctor will use an artificial valve to replace your poorly working mitral valve.
The mitral valve is a complex structure regulating forward flow of blood between the left atrium and left ventricle (LV). Multiple disease processes can affect its proper function, and when these diseases cause severe mitral regurgitation (MR), optimal treatment is repair of the native valve. The mitral valve (MV) is a dynamic structure with multiple components that have complex interactions. Computational modeling through finite element (FE) analysis is a valuable tool to delineate the biomechanical properties of the mitral valve and understand its diseases and their repairs. In this review, we present an overview of relevant mitral valve diseases, and describe the evolution of FE models of surgical valve repair techniques.. ...
The heart has four valves that regulate blood flow through the heart. The mitral valve is the heart valve located between the left atrium, or upper chamber of the heart, and left ventricle, or lower chamber of the heart. After the left atrium fills with blood the mitral valve opens to allow the blood to flow down into the left ventricle. When the heart pumps and the left ventricle contracts, the mitral valve closes and blood flows outward through the aortic valve (the exit valve of the heart) and into the circulation of the body.. If the mitral valve does not close properly, blood flows backwards into the left atrium. This back flow is called regurgitation. Small amounts of regurgitation are well tolerated, but if the amount increases over time, symptoms such as breathlessness and weakness can result. The heart muscle grows larger due to increased work load and becomes a less efficient pump.. Medicines or heart valve surgery may be recommended as treatment.. ...

The choice of prosthesis for mitral valve replacement still remains controversial. This study assessed mortality, bleeding events and reoperation in patients who underwent mitral valve replacement surgery with biological or mechanical substitutes. A total of 352 patients who underwent mitral valve replacement surgery between 1990 and 2008 with 5 to 23 years of follow-up were retrospectively evaluated in a cohort study. The 5, 10, 15 and 20 year survival rates after surgery using a mechanical substitute were 87.7%, 74.2%, 69.3% and 69.3%, respectively, while after surgery with a biological substitute, they were 87.6%, 71.0%, 64.2% and 56.6%, respectively. There was no significant difference between the two groups (p = 0.38). In the multivariate analysis, the factors associated with death were age, bleeding events and renal failure. The probabilities of remaining free of reoperation at 5, 10, 15 and 20 years after surgery using a mechanical substitute were 94.4%, 92.7%, 92.7% and 92.7%; after surgery with
In vitro studies have demonstrated that shear forces ,3000 dynes/cm2are associated with significant red cell destruction (24). A recent report by Garcia et al. provided new insights into the pathophysiology of mitral prosthetic hemolysis (8). Using fluid dynamic simulation models, they showed that rapid acceleration, fragmentation and collision jets were associated with high shear stress and may therefore produce hemolysis, whereas free and slow deceleration jets were not. However, their study included only 3 patients with hemolytic anemia after mitral valve repair.. This study was therefore conducted to determine the hydrodynamic mechanisms involved in the occurrence of hemolysis after mitral valve repair as assessed by serial two-dimensional and color flow Doppler echocardiography. We found that clinically significant hemolysis in patients after mitral valve repair is associated with distinct patterns of regurgitant flow that have been shown (8)to be associated with high shear stress: ...
Percutaneous mitral valve repair (MVR) is used to treat mitral regurgitation (MR; depicted in the image below). Percutaneous procedures used to treat valvular heart disease were first developed decades ago; the first pulmonic balloon valvuloplasty was reported in 1982 and was quickly followed by applications to the aortic and mitral valves.
In the wake of transcatheter aortic valve replacement revolutionizing the treatment of aortic stenosis, sizeable interest has arisen in the development of percutaneous technologies to treat patients with mitral valve disease. Thus, when a percutaneous method of edge-to-edge mitral valve repair (TMVr) using the MitraClip device (Abbott Vascular) was introduced, this device was met with considerable enthusiasm.
We previously discussed about the mitral valve M-mode in PLAX view and E-point septal separation (EPSS). EPSS is the distance between peak of the E-wave (early diastolic wave) of the mitral tracing and interventricular septum. Elevated EPSS is a sign of LV systolic dysfunction. See the following infographic and illustration of the normal mitral M-mode.…
We successfully performed coronary artery bypass grafting and mitral valve replacement in a 72-year-old man who had undergone a left pneumonectomy 13 years previously due to a malignant mass. The patient was admitted to our clinic with symptoms of dyspnoea, palpitations, chest pain and fatigue. He was diagnosed with mitral valve disease and two-vessel coronary artery disease, as seen from echocardiography and catheterisation studies. Conventional cardiopulmonary bypass grafting was performed following sternotomy. The patient's heart was completely displaced to the left hemithorax. Saphenous vein grafts were harvested. Distal anastomoses were performed with the use of the on-pump beating heart technique without cross clamping. Afterwards a cross clamping was placed and a left atriotomy was performed. The mitral valve was severely calcific. A mitral valve replacement was performed using number 27 mechanical valve after the valve had been excised. The patient's postoperative course was uneventful
By Allareddy, V Ward, M M; Ely, J W; Allareddy, V; Levett, J Aim. Heart valve replacement surgeries account for 20% of all cardiac procedures. In-hospital mortality rates are approximately 6% for aortic valve replacements and 10% for mitral valve replacements. The objectives of the study are to provide nationally representative estimates of complications following aortic and mitral valve replacements and to quantify the impact of different types of complications on in-hospital outcomes. Methods. The Nationwide Inpatient Sample was analyzed for years 2000-2003. The effect of complications on in-hospital mortality, length of stay (LOS), and hospital charges were examined using bivariate and multivariable logistic and linear regression analyses. The confounding effects of age, sex, primary diagnosis, type of valve replacement, type of admission, comorbid conditions, and hospital characteristics were adjusted. Results. A total of 43 909 patients underwent aortic valve replacement as the primary ...

In order to investigate the functional effects of mitral valve surgery, echocardiograms showing left ventricular dimension were recorded and digitised in 14 normal subjects and 129 patients after mitral valve surgery. Measurements were made of peak rate of increase of dimension (dD/dt) and duration of rapid filling, studies on left ventriculograms in 36 patients having shown close correlation between these values and changes in cavity volume. In 14 patients with mitral stenosis, peak dD/dt was reduced to 7-2 +/ 1-5 cm/s, and filling period prolonged to 330 +/- 65 ms, compared with normal (16-0 +/- 3-2 cm/s, and 160 +/- 50 ms, respectively), and after mitral valvotomy, these values improved significantly (10-4 +/- 2-7 cm/s and 245 +/- 55 ms). Characteristic abnormalities were found in 67 patients with mitral prostheses. Values for the Björk-Shiley (10-5 +/- 4-2 cm/s and 180 +/- 80 ms) and Hancock (10-3 +/- 3-7 cm/s, 245 +/- 80 ms) values were similar, and both superior to the Starr-Edwards (7-4 ...

Systolic Murmurs - Mitral Valve Prolapse. You are listening to a typical example of the murmur caused by mitral valve prolapse. The pathophysiology of mitral valve prolapse is varied, but can be thought of as an inability of the papillary muscles or chordae tendineae to completely tether the mitral valve during the late stages of systole. As the left ventricle chamber decreases in size, the papillary muscles and/or the chordae fail to maintain tension on the mitral valve, and it prolapses with a brief regurgitant period into the left atrium. This is a common syndrome which frequently is associated with young adult women, and can present as attacks of palpitations, anxiety, or light-headedness. Although it is usually a mild symptom, patients with mitral valve prolapse with evidence of regurgitation by echo should be given antibiotic prophylaxis during invasive procedures to help prevent bacterial endocarditis..

The patient was a 12-year-old girl with rheumatic mitral stenosis.. The development of the heart-lung machine in the 1950s paved the way for replacement of the mitral valve with an artificial valve in the 1960s. For decades after, mitral valve replacement was the only surgical option for patients with a severely diseased mitral valve. However, there are some significant downsides to a prosthetic mitral valve. Infection of the valve can occur, which is dangerous and difficult to treat. Patients with mechanical heart valves are required to take blood thinners for the rest of their lives, which presents a risk of bleeding complications. The artificial mitral valve has an elevated risk of stroke. Patients with mechanical heart valves who use warfarin for anticoagulation have to be on long-term anticoagulation therapy. This means they must go to the clinic ...
A mitral valve annuloplasty ring and method for implanting a mitral valve annuloplasty ring to treat mitral insufficiency by reestablishing the normal shape and contour of the mitral valve annulus. The annuloplasty ring is flexible and can be readily adjusted to different sizes and shapes. The method substantially eliminates scarring subsequent to the annuloplasty procedure to maintain flexibility of the ring and the annulus indefinitely.
Mitral valve regurgitation is when the mitral valve in the heart is leaky. Its also known as mitral insufficiency. The mitral valve is one of the hearts four valves. These valves help the blood flow through the hearts four chambers and out to the body. The mitral valve lies between the left atrium and the left ventricle. Normally, the mitral valve prevents blood flowing back into the left atrium from the left ventricle. In mitral valve regurgitation, however, some blood leaks back over the valve. It doesnt just flow forward into the ventricle the way it should. Because of this, the heart has to work harder than it should to get blood out to the body.

The outcome in functional mitral regurgitation after aortic valve replacement is unclear. A frail 82-year-old woman with severe aortic valve regurgitation and mild to moderate functional mitral valve regurgitation (NYHA functional class III) was referred to our clinic. In consideration of her frail condition, aortic valve replacement without mitral surgery was performed. She had hemodynamic instability and difficulty to wean off cardiopulmonary bypass caused by severe functional mitral valve regurgitation with left ventricular dilatation. A central Alfieri edge-to-edge stitch was placed between the anatomical middle of the two leaflets of the mitral valve after reinstitution of cardiopulmonary bypass. This eliminated the mitral regurgitation, which enabled successful separation from cardiopulmonary bypass.

Methods. A retrospective study was made of 302 patients having mitral valve repair or replacement and CABG from January 1987 through December 1996. Risk factors for death, for development of New York Heart Association class III or IV congestive heart failure (CHF), and recurrent ...
with the advent of real-time 3-dimensional transesophageal echocardiography (3d tee), rapid creation of high-quality, true-to-life images of mitral valve anatomy and pathology has become possible in the vast majority of patients (1). In addition to common mitral valve lesions, such as degenerative mitral valve disease, 3D TEE is invaluable for characterizing less frequently encountered disorders, including endocarditis and its complications (2). Precise localization of leaflet perforations can be challenging on 2-dimensional images, particularly for non-experts. While the affected scallop can often be identified with the help of color Doppler, it may be difficult to pinpoint the site of perforation with respect to the leaflet tip. The addition of 3D TEE often provides clarity in this regard, helping to determine the feasibility of surgical repair. In this iPIX, we demonstrate the role of real-time 3D TEE in characterizing mitral leaflet perforations at various sites. Asterisks denote the aorta ...

Mitral valve prolapse (MVP; a.k.a. floppy mitral valve syndrome, systolic click murmur syndrome or billowing mitral leaflet) is a valvular heart disease characterized by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole. It is the primary form of myxomatous degeneration of the valve. There are various types of MVP, broadly classified as classic and nonclassic. In its nonclassic form, MVP carries a low risk of complications and often can be kept minimal by dietary attention. In severe cases of classic MVP, complications include mitral regurgitation, infective endocarditis, congestive heart failure, and, in rare circumstances, cardiac arrest. The diagnosis of MVP depends upon echocardiography, which uses ultrasound to visualize the mitral valve. The prevalence of MVP is estimated at 2-3% of the population. The condition was first described by John Brereton Barlow in 1966. In consequence, it may also be referred to as Barlows syndrome, and was ...
Mitral valve insufficiency (MI) is inadequate closure of the valve that separates the left atrium from the left ventricle. This disorder can be due to backward movement of the valve (prolapsing), thickening of the valve, gradual (chronic) degeneration of the valve, bacterial infection of the valve, narrowing of the opening in the valve or dysfunction of the muscles or chords controlling the valve. Chronic degeneration of the valve is the most common cause of MI in dogs and cats.. This inability to close the mitral valve completely causes regurgitation (backward flow) of blood into the left atrium of the heart. This regurgitation increases the amount of blood that the left atrium has to pump, which may lead to volume overloading. As a means of compensation, the left atrium may dilate (expand). This is a condition known as left atrial enlargement. In later stages of disease, the left ventricle and veins of the lungs are generally enlarged as well.. Signs of MI include coughing, increased heart ...
Double orifice mitral valve is a rare congenital anomaly presenting as the division of the mitral orifice into two anatomically distinct orifices, it is most often associated with other congenital heart defects such as left-sided obstructive lesions, ventricular septal defects or aortic coarctation. We report the case of a 15 years old boy, admitted for arterial hypertension, auscultation revealed a rude aortic systolic murmur. Femoral pulses were weak. Owing to the suspicion of aortic coarctation, transthoracic echocardiography was performed, the aortic coarctation with dilation of the aorta proximal to the stenosis was confirmed and bicuspid aortic valve was found with good function. The mitral valve was dysmorphic, having two orifices; it was divided into 2 separate valve orifices by a fibrous bridge. No mitral or aortic regurgitation was documented by color Doppler flow imaging. The left ventricular ejection fraction was normal. There was a small peri membranous ventricular septal defect with left
To treat mitral valve regurgitation surgically, the options are to repair or replace the mitral valve. Repair of the heart valve may be recommended if it is likely that the valve can be repaired and that the repair will last a long time.. Valve replacement may be recommended if your mitral valve is seriously damaged and cannot be repaired.. The decision about whether to repair or replace a valve is based on many things, including your general health, the condition of the damaged valve, the presence of other health conditions, and the expected benefits of surgery. In some cases, the decision clearly may be in favor of repair or in favor of replacement.. ...
Mitral valve prolapse is a condition that occurs when the mitral valve of the heart doesnt work properly. This valve controls the flow of blood between the upper left chamber of the heart (the left atrium) and the lower left chamber (the left ventricle). Normally, the mitral valve forms a tight seal between the two when it needs to. But with mitral valve prolapse, the valve doesnt seal tightly, which can cause blood to flow back in the opposite direction. This in turn can cause a variety of heart complications.

METHODS: Between January 2000 and December 2015, a total of 1742 patients who underwent mitral valve surgery were identified. Of these, 1622 operations were performed by consultants (Group I) and 120 operations were performed by trainees (Group II). A propensity score-matched analysis has been used to minimize selection bias. Early postoperative outcomes were defined as ...
Unlike reported cases in which a transcatheter aortic valve device was implanted in the mitral position in the setting of dense annular calcification or a degenerated bioprosthesis, it might be feasible to use the FORTIS device in the setting of primary or secondary noncalcific MR. This first report of three patients with 6-month follow-up after transcatheter mitral valve replacement is encouraging, yet it might be premature to draw firm conclusions about procedural complication rates and clinical outcomes from this very small single-center experience. If positive results are borne out in a larger, multicenter trial or trials, then transcatheter mitral valve replacement with this or another device might provide an attractive alternative to the limited MR reduction afforded by transcatheter edge-to-edge repair.. ...
Introduction: Pulmonary veins isolation (PVI) is useful method in patients (pts) with mitral valve disease (MVD) and chronic atrial fibrillation (AF) during prosthetic valve implantation. The aim of the study: To evaluate e.ectiveness of PVI in the treatment of AF in pt with MVD during valve implantation.

There were 6 cases of paroxysmal AF,1 pt ...
Most people with mitral valve prolapse dont need any treatment. In fact, this condition usually has no effect on your health. About two of every 100 people with this condition have complications. You may need surgery to fix the valve if your valve is too leaky or if you are having lots of symptoms. You may also have to limit your participation in competitive sports. Ask your doctor if you are in this group.. If your mitral valve prolapse causes chest pains or other symptoms, your doctor might prescribe medicines such as beta blockers to make your symptoms better.. Some people get an infection in the leaky valve when they have surgery or dental work. You might take antibiotics before surgery or dental work to prevent this infection. Remind your dentists and doctors that you have mitral valve prolapse so that you can get a prescription for antibiotics when you are going to have surgery or dental work. ...

The left ventricular apex has excellent accessibility to the aortic valve, mitral valve, left ventricular outflow tract and thoracic aorta. Although the number of transapical approach in transcatheter aortic valve replacement has been decreasing in recent years, it is still a useful option for patients with very poor peripheral vascular access. The apex has been chosen as a primary access site for many devices of transcatheter mitral valve repair/replacement and mitral valve-in-valve procedures. Additionally, the transapical approach has been used for other transcatheter cardiovascular interventions such as paravalvular leak repair after mitral or aortic valve replacement, pseudoaneurysm repair of the left ventricular outflow tract, and thoracic endovascular aortic repair ...

Degenerative mitral stenosis (DMS) is characterized by decreased mitral valve (MV) orifice area and increased transmitral pressure gradient due to chronic noninflammatory degeneration and subsequent calcification of the fibrous mitral annulus and the MV leaflets. The true prevalence of DMS in the general population is unknown. DMS predominantly affects elderly individuals, many of whom have multiple other comorbidities. Transcatheter MV replacement techniques, although their long-term outcomes are yet to be tested, have been gaining popularity and may emerge as more effective and relatively safer treatment option for patients with DMS. Echocardiography is the primary imaging modality for evaluation of DMS and related hemodynamic abnormalities such as increased transmitral pressure gradient and pulmonary arterial pressure. Classic echocardiographic techniques used for evaluation of mitral stenosis (pressure half time, proximal isovelocity surface area, continuity equation, and MV area ...
Native valve endocarditis (NVE) refers to infectious endocarditis involving a patients own (native) heart valve. Crude incidence of NVE is 6.2 per 100,000 people per year, and is highest in older age groups.5 The pathogenesis of NVE begins with endocardial trauma resulting in alteration of the valvular endocardial surface; this allows deposition of fibrin and platelets with subsequent attachment of bacteria. Endocardial injury may be secondary to rheumatic valvulitis or other leaflet disease, or valvular or annular calcification.5 Common reasons for bacteremia or fungemia predisposing to NVE include use of long-term indwelling catheters, intravenous drug abuse, and fungemia associated with prolonged antibiotic therapy.6,7 Although vegetations may be seen anywhere on the leaflets or the chordae, the usual site at which infective NVE of the mitral valve causes valvular destruction and invasion is at the base of the atrial aspect of the mitral valve leaflets. Annular or subannular invasion may ...
The mitral valve regulates the flow of blood from the upper-left chamber (the left atrium) to the lower-left chamber (the left ventricle). Three diseases of the mitral valve are mitral valve prolapse, mitral regurgitation, and mitral stenosis.
Described here are methods, devices, and kits for treating a prolapsed valve leaflet. The devices generally comprise a flexible cord, a first anchor attached to the cord at its distal end, and a second anchor slidably attached to the cord. The first anchor may be configured to secure the cord to cardiac tissue located below a prolapsed valve leaflet and the second anchor may be configured to secure into the prolapsed valve leaflet. Also described are methods for treating a prolapsed valve including the steps of securing a first anchor to cardiac tissue located below the prolapsed mitral valve leaflet, securing a second anchor to the prolapsed mitral valve leaflet, tensioning a cord connecting the two anchors and securing the cord. Kits including the described devices are also provided.
