Mitral Valve Insufficiency
Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.
Mitral Valve
The valve between the left atrium and left ventricle of the heart.
Aortic Valve Insufficiency
Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).
Tricuspid Valve Insufficiency
Backflow of blood from the RIGHT VENTRICLE into the RIGHT ATRIUM due to imperfect closure of the TRICUSPID VALVE.
Pulmonary Valve Insufficiency
Backflow of blood from the PULMONARY ARTERY into the RIGHT VENTRICLE due to imperfect closure of the PULMONARY VALVE.
Mitral Valve Prolapse
Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.
Venous Valves
Flaps within the VEINS that allow the blood to flow only in one direction. They are usually in the medium size veins that carry blood to the heart against gravity.
Aortic Valve
The valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle.
Heart Valve Diseases
Pathological conditions involving any of the various HEART VALVES and the associated structures (PAPILLARY MUSCLES and CHORDAE TENDINEAE).
Mitral Valve Stenosis
Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.
Heart Valve Prosthesis Implantation
Surgical insertion of synthetic material to repair injured or diseased heart valves.
Cardiac Surgical Procedures
Surgery performed on the heart.
Mitral Valve Annuloplasty
A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annulus of the MITRAL VALVE. It includes shortening the circumference of the annulus to improve valve closing capacity and reinforcing the annulus as a step in more complex valve repairs.
Heart Valve Prosthesis
A device that substitutes for a heart valve. It may be composed of biological material (BIOPROSTHESIS) and/or synthetic material.
Chordae Tendineae
The tendinous cords that connect each cusp of the two atrioventricular HEART VALVES to appropriate PAPILLARY MUSCLES in the HEART VENTRICLES, preventing the valves from reversing themselves when the ventricles contract.
Aortic Valve Stenosis
A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
Adrenal Insufficiency
Conditions in which the production of adrenal CORTICOSTEROIDS falls below the requirement of the body. Adrenal insufficiency can be caused by defects in the ADRENAL GLANDS, the PITUITARY GLAND, or the HYPOTHALAMUS.
Treatment Outcome
Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.
Tricuspid Valve
The valve consisting of three cusps situated between the right atrium and right ventricle of the heart.
Bioprosthesis
Prosthesis, usually heart valve, composed of biological material and whose durability depends upon the stability of the material after pretreatment, rather than regeneration by host cell ingrowth. Durability is achieved 1, mechanically by the interposition of a cloth, usually polytetrafluoroethylene, between the host and the graft, and 2, chemically by stabilization of the tissue by intermolecular linking, usually with glutaraldehyde, after removal of antigenic components, or the use of reconstituted and restructured biopolymers.
Pulmonary Valve
A valve situated at the entrance to the pulmonary trunk from the right ventricle.
Venous Insufficiency
Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.
Renal Insufficiency
Conditions in which the KIDNEYS perform below the normal level in the ability to remove wastes, concentrate URINE, and maintain ELECTROLYTE BALANCE; BLOOD PRESSURE; and CALCIUM metabolism. Renal insufficiency can be classified by the degree of kidney damage (as measured by the level of PROTEINURIA) and reduction in GLOMERULAR FILTRATION RATE.
Echocardiography, Transesophageal
Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues using a transducer placed in the esophagus.
Rheumatic Heart Disease
Cardiac manifestation of systemic rheumatological conditions, such as RHEUMATIC FEVER. Rheumatic heart disease can involve any part the heart, most often the HEART VALVES and the ENDOCARDIUM.
Echocardiography
Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic.
Exocrine Pancreatic Insufficiency
A malabsorption condition resulting from greater than 10% reduction in the secretion of pancreatic digestive enzymes (LIPASE; PROTEASES; and AMYLASE) by the EXOCRINE PANCREAS into the DUODENUM. This condition is often associated with CYSTIC FIBROSIS and with chronic PANCREATITIS.
Echocardiography, Three-Dimensional
Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)
Cardiac Valve Annuloplasty
A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annuli of HEART VALVES. It includes shortening the circumference of the annulus to improve valve closing capacity and reinforcing the annulus as a step in more complex valve repairs.
Placental Insufficiency
Failure of the PLACENTA to deliver an adequate supply of nutrients and OXYGEN to the FETUS.
Phonocardiography
Graphic registration of the heart sounds picked up as vibrations and transformed by a piezoelectric crystal microphone into a varying electrical output according to the stresses imposed by the sound waves. The electrical output is amplified by a stethograph amplifier and recorded by a device incorporated into the electrocardiograph or by a multichannel recording machine.
Endocarditis, Bacterial
Inflammation of the ENDOCARDIUM caused by BACTERIA that entered the bloodstream. The strains of bacteria vary with predisposing factors, such as CONGENITAL HEART DEFECTS; HEART VALVE DISEASES; HEART VALVE PROSTHESIS IMPLANTATION; or intravenous drug use.
Echocardiography, Doppler, Color
Echocardiography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image.
Endocarditis
Inflammation of the inner lining of the heart (ENDOCARDIUM), the continuous membrane lining the four chambers and HEART VALVES. It is often caused by microorganisms including bacteria, viruses, fungi, and rickettsiae. Left untreated, endocarditis can damage heart valves and become life-threatening.

Frequency and long term follow up of valvar insufficiency caused by retrograde aortic radiofrequency catheter ablation procedures. (1/1634)

OBJECTIVE: To assess the frequency of valvar complications caused by left sided radiofrequency catheter ablation using the retrograde aortic technique. METHODS: 179 patients (118 male) with a mean (SD) age of 43 (17) years underwent 216 procedures at one centre. The target of the ablation was an accessory atrioventricular pathway in 144 patients, the atrioventricular junction in 29 patients, and a ventricular tachycardia in six patients. In 25 patients structural heart disease was identified before the procedure (ischaemic heart disease 10, cardiomyopathy nine, valvar three, other three). Echo/Doppler examinations were performed the day before the procedure and within 24 hours postablation; the investigations were all reviewed by the same investigator. Patients with identified valvar injury caused by the procedure were followed for 42 (7) months. RESULTS: Valvar injury caused by the ablation procedure was identified in four young (age 30 (8) years), otherwise healthy patients with left lateral atrioventricular accessory pathways. Mild mitral insufficiency with a central regurgitation jet was detected in two patients and remained unchanged at follow up. Mild aortic insufficiency was detected in another two patients. In one of these the regurgitation jet was central and remained unchanged at follow up. In one patient the regurgitation jet was located between the non-coronary and left cusps in relation to a loosely attached structure. Both the structure and the valvar regurgitation disappeared during follow up. No clinical complications occurred in any of the patients during follow up. CONCLUSION: In this study, the frequency of valvar complications after left sided radiofrequency catheter ablation using the retrograde aortic technique was 1.9%.  (+info)

Chordal force distribution determines systolic mitral leaflet configuration and severity of functional mitral regurgitation. (2/1634)

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)

Effects of permanent dual-chamber pacing on mitral regurgitation in hypertrophic obstructive cardiomyopathy. (3/1634)

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)

Symptomatic mitral myxomatous transformation in the elderly. (4/1634)

The clinical and pathological features of four patients with intractable heart failure, due to myxomatous change in the mitral valve, are described. It is suggested that this change may represent a response of ageing connective tissue to mechanical stress.  (+info)

An evaluation of left ventricular function after surgery for pure mitral regurgitation using dobutamine-stress echocardiography--should the mitral complex be preserved? (5/1634)

To evaluate the importance of preserving the mitral complex, clinical outcomes and postoperative left ventricular (LV) functions of 175 patients with pure mitral regurgitation (MR) were analyzed. They were divided into three groups; patients who had conventional mitral valve replacement (cMVR; n = 47), posterior mitral leaflet preserved MVR (pMVR; n = 66) or mitral valvuloplasty (MVP; n = 62). There was no operative death or hospital death in this study. The actuarial survival rate was 85.2% in cMVR, 78.5% in pMVR, and 84.7% in MVP at 10 years after operation. The actuarial freedom from reoperation 10 years postoperatively was 100% in cMVR, 97.9% in pMVR, 85.8% in MVP. The actuarial freedom from thromboembolism (TE) at 10 years was 92.2% in cMVR, 87.1% in pMVR, 93.5% in MVP. Freedom from all types of events including non-cardiac death was 78.3% in cMVR, 64.8% in pMVR, 65.3% in MVP at 10 years, respectively. Pre- and postoperative LV function was evaluated using echocardiography. Patients with MVP had better LV performance than those with MVR. However, there was no significant difference between the cMVR and pMVR groups. For further estimation of postoperative LV function, dobutamine-stress echocardiography (DSE) was performed. The results of DSE revealed that the LV contractility in MVP was obviously better than those in MVR groups especially in systole. The change in ejection fraction (EF) from baseline to peak dobutamine stress in the pMVR group was significantly greater than in cMVR. This study supports the concept that the preservation of continuity between the mitral annulus and papillary muscle plays an important role in clinical outcome and postoperative LV function. In conclusion, MVP should be a first choice as an operative method for pure MR when technically feasible. When it is impossible to perform MVP, pMVR, not cMVR, should be the next choice. This study suggests that preservation of papillary muscle-mitral annular continuity during mitral valve surgery for pure MR is beneficial to LV systolic function.  (+info)

Three-dimensional color Doppler: a clinical study in patients with mitral regurgitation. (6/1634)

OBJECTIVES: The purpose of this study was to assess the clinical feasibility of three-dimensional (3D) reconstruction of color Doppler signals in patients with mitral regurgitation. BACKGROUND: Two-dimensional (2D) color Doppler has limited value in visualizing and quantifying asymmetric mitral regurgitation. Clinical studies on 3D reconstruction of Doppler signals in original color coding have not yet been performed in patients. We have developed a new procedure for 3D reconstruction of color Doppler. METHODS: We studied 58 patients by transesophageal 3D echocardiography. The jet area was assessed by planimetry and the jet volumes by 3D Doppler. The regurgitant fractions, the volumes, and the angiographic degree of mitral regurgitation were assessed in 28 patients with central jets and compared with those of 30 patients with eccentric jets. RESULTS: In all patients, jet areas and jet volumes significantly correlated with the angiographic grading (r = 0.73 and r = 0.90), the regurgitant fraction (r = 0.68 and r = 0.80) and the regurgitant volume (r = 0.66 and r = 0.90). In patients with central jets, significant correlations were found between jet area and angiography (r = 0.86), regurgitant fraction (r = 0.64) and regurgitant volume (r = 0.78). No significant correlations were found between jet area and angiography (r = 0.53), regurgitant fraction (r = 0.52) and regurgitant volume (r = 0.53) in the group of patients with eccentric jets. In contrast, jet volumes significantly correlated with angiography (r = 0.90), regurgitant fraction (r = 0.75) and regurgitant volume (r = 0.88) in the group of patients with eccentric jets. CONCLUSIONS: Three-dimensional Doppler revealed new images of the complex jet geometry. In addition, jet volumes, assessed by an automated voxel count, independent of manual planimetry or subjective estimation, showed that 3D Doppler is also capable of quantifying asymmetric jets.  (+info)

Three-dimensional Doppler. Techniques and clinical applications. (7/1634)

AIMS: Colour Doppler is the most widely used technique for assessing valve disease, but eccentric regurgitant jets cannot be visualized and measured by conventional 2D techniques. We have developed a new procedure for three-dimensional (3D) reconstruction of colour Doppler signals. METHODS AND RESULTS: Fifty patients with mitral regurgitation underwent transoesophageal echocardiography and 3D acquisition. The severity of mitral regurgitation was assessed by angiography and the regurgitant volumes were measured by pulsed Doppler. The jet areas were calculated by planimetry from conventional colour Doppler; the jet volumes were obtained by 3D Doppler. A higher degree of mitral regurgitation was found in the patients with eccentric jets. While jet areas showed poor correlation with regurgitant volumes (r = 0.61), jet volumes correlated significantly with regurgitant volumes (r = 0.93; P < 0.001). While jet areas failed to identify patients with different grades of regurgitation, jet volumes could so discriminate. CONCLUSIONS: 3D Doppler revealed new patterns of regurgitant flow and allowed a more accurate semiquantitative assessment of complex asymmetrical regurgitant jets. Three-dimensional colour Doppler has a great potential for becoming a reference method for the assessment of patients with heart valve disease.  (+info)

The Mitral Regurgitation Index: an echocardiographic guide to severity. (8/1634)

OBJECTIVES: The purpose of this study was to develop a semiquantitative index of mitral regurgitation severity suitable for use in daily clinical practice and research. BACKGROUND: There is no simple method for quantification of mitral regurgitation (MR). The MR Index is a semiquantitative guide to MR severity. The MR Index is a composite of six echocardiographic variables: color Doppler regurgitant jet penetration and proximal isovelocity surface area, continuous wave Doppler characteristics of the regurgitant jet and tricuspid regurgitant jet-derived pulmonary artery pressure, pulse wave Doppler pulmonary venous flow pattern and two-dimensional echocardiographic estimation of left atrial size. METHODS: Consecutive patients (n = 103) with varying grades of MR, seen in the Adult Echocardiography Laboratory at UCSF, were analyzed retrospectively. All patients were evaluated for the six variables, each variable being scored on a four point scale from 0 to 3. The reference standards for MR were qualitative echocardiographic evaluation by an expert and quantitation of regurgitant fraction using two-dimensional and Doppler echocardiography. A subgroup of patients with low ejection fraction (EF < 50%) were also analyzed. RESULTS: The MR Index increased in proportion to MR severity with a significant difference among the three grades in both normal and low EF groups (F = 130 and F = 42, respectively, p < 0.0001). The MR Index correlated with regurgitant fraction (r = 0.76, p < 0.0001). An MR Index > or =2.2 identified 26/29 patients with severe MR (sensitivity = 90%, specificity = 88%, PPV = 79%). No patient with severe MR had an MR Index <1.8 and no patient with mild MR had an MR Index >1.7. CONCLUSIONS: The MR Index is a simple semiquantitative estimate of MR severity, which seems to be useful in evaluating MR in patients with a low EF.  (+info)

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.

Mitral Valve Insufficiency | IVG HospitalsMitral Valve Insufficiency | IVG Hospitals
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 ...

New Techniques to Evaluate Mitral Regurgitation - Full Text View - ClinicalTrials.govNew Techniques to Evaluate Mitral Regurgitation - Full Text View - ClinicalTrials.gov
Echocardiography is currently the technique of choice to assess the etiology and severity of mitral regurgitation (MR). Multiple 2D and Doppler parameters are assessed in an integrated fashion and the proximal flow convergent zone of the mitral regurgitation jet is used to calculate effective regurgitant orifice area and regurgitant volume. These measurements have been shown to have important prognostic information. In the last two years, the development of transesophageal imaging with 3D capability has allowed a better visualization of mitral leaflet pathology. Color Doppler 3D studies have shown that 2D methods generally underestimate mitral regurgitant volume. Magnetic resonance techniques have recently been developed to quantitate flow and calculate regurgitant volumes.. The purpose of this study is to evaluate newer methods of quantitating mitral regurgitation severity using real-time 3D echocardiography (RT3DE) and cardiac magnetic resonance imaging (CMR). Although RT3DE measurements have ...

Mechanism of decreased forward stroke volume in children and swine with ventricular septal defect and failure to thrive ::...
Children with ventricular septal defect (VSD) often demonstrate failure to thrive (Ff1). Such patients usually have reduced systemic cardiac output which has been postulated as a cause for their growth retardation. This study was conducted to ascertain the mechanism of the reduced cardiac output in children with VSD and FT11 and also in a porcine model of VSD. Forward stroke volume was reduced in VSD-FIT children, 31±8 ml/m2, compared to normal children, 49±15 ml/m2 (P , 0.05), but was not reduced in children with VSD and normal growth and development (41±16 ml/m2). Forward stroke volume was also reduced in swine with VSD compared to controls. Contractility assessed by mean velocity of circumferential shortening (Vd) corrected for afterload was similar in normals and VSD-FTI children. Contractile performance was also similar in normal and VSD swine. Afterload assessed as systolic stress was similar in FIT-VSD children and normal subjects. Preload assessed as end-diastolic stress was ...

Chronic ischemic mitral regurgitation (cIMR) remains a vexing problem for a large number of patients and their respective clinicians. It is estimated that ≈2 million Americans experience cIMR, and this number is likely to increase with an aging general population and improved survival rates for myocardial infarction.1 Despite the large number of patients with this disease, relatively few patients are referred for surgical therapy. This is reflected in the fact that the largest surgical series to date consist of only a few hundred patients operated on over a several-year interval.2,3. Article see p 2720. One important reason for the small number of cIMR surgical referrals is the lack of evidence of a survival benefit associated with surgery,4 despite observed improvements in heart failure symptoms and left ventricular (LV) dimensions.5 Improvements in reverse LV remodeling and functional status have also been demonstrated in patients with idiopathic dilated cardiomyopathy who undergo a ...

A Comparative Assessment of Echocardiographic Parameters for Determini by S. Uretsky, E. Argulian et al.A Comparative Assessment of Echocardiographic Parameters for Determini by S. Uretsky, E. Argulian et al.
BACKGROUND: The American Society of Echocardiography (ASE) guidelines suggest the use of several echocardiographic methods to assess mitral regurgitation severity using an integrated approach, without guidance as to the weighting of each parameter. The purpose of this multicenter prospective study was to evaluate the recommended echocardiographic parameters against a reference modality and develop and validate a weighting for each echocardiographic measure of mitral regurgitation severity. METHODS: This study included 112 patients who underwent evaluation with echocardiography and magnetic resonance imaging (MRI). Echocardiographic parameters recommended by the ASE were included and compared with MRI-derived regurgitant volume (MRI-RV). RESULTS: Echocardiographic parameters that correlated best with MRI-RV were proximal isovelocity surface area (PISA) radius (r = 0.65, P | .0001), PISA-derived effective regurgitant orifice area (r = 0.65, P | .0001), left ventricular end-diastolic volume (r = 0.56, P |

In recent years, transcatheter mitral valve repair using the MitraClip (Abbott Vascular, Abbott Park, Illinois) has become a prevalent approach to treat significant mitral regurgitation (MR) in patients deemed inoperable or at high surgical risk (1-3). The technique emulates the surgical edge-to-edge suture (4) by using 1 or more transseptally introduced clips to approximate the mitral leaflets at the origin of the regurgitant jet. Although the reduction in MR severity achieved by MitraClip implantation has been shown to persist in the majority of patients, recurrence of significant MR has been reported (2,3,5).. Different mechanisms may account for MR recurrence. On the one hand, progression of the underlying disease that originally gave rise to (functional or degenerative) MR may lead to recurrent regurgitation despite initially successful MitraClip therapy. On the other hand, loss of leaflet insertion (LLI) into the clip imperatively causes a relapse of MR. LLI may be the consequence of ...

Ischemic mitral regurgitation (IMR) is associated with decreased quality of life and long-term survival. Although extensive mechanistic research has been conducted, the optimal management of IMR remains elusive. Clinical studies in the past often included MR of multiple etiologies, including degenerative or nonischemic origin and IMR grouped into the same category, leading to confusion and incorrect conclusions regarding the natural history and true long-term impact of IMR. It is important to distinguish IMR from mitral regurgitation resulting from nonischemic etiologies. Mitral regurgitation is often associated with coronary artery disease without a direct cause-and-effect relationship. Given the prevalence of coronary artery disease, the association of myocardial infarction and nonischemic mitral regurgitation is a common clinical association. IMR must be distinguished from mitral insufficiency caused by degenerative, rheumatic, congenital, and infectious etiologies, as well as that arising ...

Percutaneous mitral valve repair using the MitraClip (Abbott Vascular, Santa Clara, California) is a promising technique to treat symptomatic severe mitral regurgitation (MR) in patients at high or prohibitive surgical risk. Large observational registries of patients treated with this device for predominantly secondary MR show symptomatic relief and improvement of hemodynamics at rest (1,2). Comparative data on exercise hemodynamics before versus after percutaneous mitral valve repair therapy are currently lacking, although such data are most relevant in secondary MR. First, secondary MR is characteristically dynamic and sensitive to changes in ventricular geometry and loading conditions (3). It remains unclear whether, besides a reduction in resting MR, percutaneous mitral valve repair therapy is effective in reducing secondary MR during exercise. Second, mitral valve area is typically reduced following the procedure (4). It remains to be determined whether such mild iatrogenic stenosis might ...

Systematic overestimation of the MV SV or underestimation of ISVS R could cause the traditional PISA method to appear to underestimate continuity-based MR EROA. Identifying orifice location is often challenging, allowing both underestimation and overestimation of ISVS R. However, because flow must converge along the leaflets ventricular surface, the orifice cannot be behind this surface. Importantly, our theoretical predictions of expected ISVS R with elongation and leaflet tenting agreed closely with our empiric R measurements, and our control series PISA EROA agreed well with their corresponding continuity EROAs, validating our measurement technique and supporting the absence of systematic errors in our ISVS R measurements.. The major potential source of overestimation of MV SV is mitral annular diameter. Our mean diameter was 3.3 cm. Mihalatos et al. (13) reported that the MV orifice becomes circular and its diameter increases progressively with MR severity. They found mean end-systolic and ...

Mitral regurgitation in coronary heart disease. | HeartMitral regurgitation in coronary heart disease. | Heart
Mitral reguritation is a relatively common finding in coronary heart disease. In this series of 127 patients, selected with a view to coronary or left ventricular surgery on the basis of severity of symptoms, the incidence was 39 (31%). Mitral regurgitation is significantly more common in patients with a history or electrocardiographic evidence of previous myocardial infarction. Clinically it may present as a pan- or late systolic or even a mid-systolic, ejection type murmur at the apex or at the left sternal edge; but in 39 per cent of the patients with angiographic mitral regurgitation no murmur was present. Angiographically important mitral regurgitation (grades 2-4/4) was usually associated with a systolic murmur; this finding was independent of ejection fractions. Left ventricular enlargement clinically or radiographically is likely to accompany mitral regurgitation but left atrial enlargement (electrocardiographically or on chest x-ray) is a more reliable pointer to mitral regurgitation ...

Automatic extraction of forward stroke volume using dynamic PET/CT - Research - Aarhus UniversityAutomatic extraction of forward stroke volume using dynamic PET/CT - Research - Aarhus University
BACKGROUND: The aim of this study was to develop and validate an automated method for extracting forward stroke volume (FSV) using indicator dilution theory directly from dynamic positron emission tomography (PET) studies for two different tracers and scanners.. METHODS: 35 subjects underwent a dynamic (11)C-acetate PET scan on a Siemens Biograph TruePoint-64 PET/CT (scanner I). In addition, 10 subjects underwent both dynamic (15)O-water PET and (11)C-acetate PET scans on a GE Discovery-ST PET/CT (scanner II). The left ventricular (LV)-aortic time-activity curve (TAC) was extracted automatically from PET data using cluster analysis. The first-pass peak was isolated by automatic extrapolation of the downslope of the TAC. FSV was calculated as the injected dose divided by the product of heart rate and the area under the curve of the first-pass peak. Gold standard FSV was measured using phase-contrast cardiovascular magnetic resonance (CMR).. RESULTS: FSVPET correlated highly with FSVCMR (r = 0.87, ...

Failures and Re-operations | Mitral Valve Repair CenterFailures and Re-operations | Mitral Valve Repair Center
The most complete and elaborate follow-up for mitral repair in contemporary literature is probably the series of Flameng and associates4 who report a series of 242 consecutive mitral repairs with serial follow-up echocardiography done at 6 month intervals. They found a freedom from moderate or severe mitral regurgitation of 71% at 7 years and found that new recurrent mitral regurgitation appeared at a rate of 3.7% per year (Figure 2). The data of Flameng and colleagues4 suggest that durability of many mitral repairs is limited; the linear recurrence rate implies that recurrent mitral regurgitation is likely a reflection of progression of underlying valve disease. This hypothesis is supported by data from mitral re-operations after previous repair, as the previous repairs are found to be intact in two-thirds of patients, with recurrent regurgitation usually due to new valve lesions (chordal rupture, fibrosis, calcification, leaflet perforation)5. Technical failure can be a major cause of ...

When should patients undergo surgery for mitral regurgitation? - Style & Hairstyles & Fashion - StylesStar.ComWhen should patients undergo surgery for mitral regurgitation? - Style & Hairstyles & Fashion - StylesStar.Com
There is controversy as to the best timing for surgery. Patients presenting with acute severe mitral regurgitation are generally critically ill and require urgent surgery. However, in patients with chronic mitral regurgitation, the timing is more uncertain.. In the past, cardiologists recommended waiting until severe symptoms developed before proceeding to surgery. However, waiting often was associated with a bad outcome, and left ventricular function did not respond well to the sudden change in afterload imposed by putting an artificial valve in a patient who had severe regurgitation. Now, many recommend operating as soon as significant symptoms develop. Some, in fact, even recommend that these patients not be treated with medication so as not to mask symptoms and that surgery be done as soon as any symptom presents.. However, replacement of a native valve with a prosthetic one is not a cure for the patient, but rather a shift to a new set of problems associated with the prosthetic valve. Newer ...

BACKGROUND: Functional mitral regurgitation (MR) is common in patients with heart failure and left ventricular (LV) dysfunction, and its severity may vary over time, depending primarily on the loading conditions. Because dynamic changes in the severity of functional MR may affect forward stroke volume, we hypothesized that exercise-induced changes in MR severity influence the stroke volume response of patients with LV dysfunction to exercise, and hence their exercise capacity. METHODS AND RESULTS: Heart failure patients (n=25; mean age 53+/-12 years) with LV dysfunction underwent dynamic bicycle exercise at steady-state levels of 30%, 60%, and 90% of predetermined peak VO2. During each exercise level, right heart pressures, cardiac output, VO2, and MR severity were measured simultaneously. During exercise, MR severity, as evaluated by the ratio of MR jet over left atrium area, increased from 15+/-8% to 33+/-15%. Peak VO2, exercise-induced changes in stroke volume, and those in capillary wedge ...

Mitral Valve Repair Versus Revascularization Alone in the Treatment of Ischemic Mitral Regurgitation | CirculationMitral Valve Repair Versus Revascularization Alone in the Treatment of Ischemic Mitral Regurgitation | Circulation
The presence and severity of MR associated with myocardial infarction has been shown to be an important prognostic factor in ischemic heart disease.1-4 Lamas et al1 reported that the 3-year survival rate after myocardial infarction was significantly lower in patients with than without residual MR (71% versus 88%), and mortality risk has been shown to be directly related to the severity of ischemic MR.2 Because revascularization alone may not resolve ischemic MR,20 MV repair together with CABG may be preferable to CABG alone, but only if correction of MR can be performed safely. We have shown here that for patients with severe MR, MV repair was superior to CABG alone in reducing ischemic MR and LV size, without increasing operative or long-term mortality rates. In patients with moderate MR, however, the operative mortality rate of the combination of CABG and MV repair was significantly higher than that of CABG alone, whereas the MR improvement rates were similar in the 2 procedures. Even if MV ...

We sought to evaluate the geometric changes of the mitral leaflets, local and global LV remodeling in patients with left ventricular dysfunction and varying degrees of Functional mitral regurgitation (FMR). Functional mitral regurgitation (FMR) occurs as a consequence of systolic left ventricular (LV) dysfunction caused by ischemic or nonischemic cardiomyopathy. Mitral valve repair in ischemic MR is one of the most controversial topic in surgery and proper repairing requires an understanding of its mechanisms, as the exact mechanism of FMR are not well defined. 136 consecutive patients mean age of 55 with systolic LV dysfunction and FMR underwent complete echocardiography and after assessing MR severity, LV volumes, Ejection Fraction, LV sphericity index, C-Septal distance, Mitral valve annulus, Interpapillary distance, Tenting distance and Tenting area were obtained. There was significant association between MR severity and echocardiogarphic indices (all p values | 0.001). Severe MR occurred more

Mitral surgery was ultimately performed in 265 patients, involving valve repair in 240 patients (90.6%) and valve replacement in 25 patients (mechanical: n = 18, bioprosthesis: n = 7). Forty patients (15.1%) underwent concomitant coronary bypass surgery and 7 had a Maze procedure. As expected, patients who underwent surgery after diagnosis versus those who remained medically managed, had larger RVol (89 ± 37 ml vs. 43 ± 32 ml, p , 0.001) and LA index (63 ± 25 ml/m2vs. 46 ± 23 ml/m2, p , 0.001). During total follow-up (including pre- and post-operative period), 80 patients died (survival: 85 ± 1.8% 5 years after diagnosis), and 26 patients died after mitral surgery (survival: 91 ± 2.0% 5 years after surgery). New onset AF occurred in 26 patients and heart failure in 15 patients.

Background: In heart failure (HF) patients the severity of mitral regurgitation (MR) at rest has a well established prognostic value and its increase during exercise further adds to an increased risk. Our goal was to define the relationship between the degree of exercise MR severity with cardiopulmonary and echocardiographic related phenotypes in a cohort of HF patients. Methods: 71 HF reduced ejection fraction patients (mean age 67±11; male 72%; ischemic etiology 61%; NYHA class I, II, III and IV 13%, 36%, 39% and 12%, mean ejection fraction 33±9%) underwent cardiopulmonary exercise test (CPET) on tiltable cycle-ergometer combined with echocardiography at rest and during exercise. The population was divided into two groups according to the degree of functional peak MR: no to mild/moderate MR (no MR, MR1+ and MR2+) vs moderate/severe MR (MR3+ and MR4+). Results: A good correlation (ρ coefficient= 0.49) was found between the degree of dynamic MR and PASP at peak exercise. Despite similar ...

MRI evaluation in patients with mitral regurgitationMRI evaluation in patients with mitral regurgitation
A combination of left ventricular volumetric quantification and phase-contrast imaging performed at level of ascending aorta, however, allows accurate and reproducible assessment of mitral regurgitation. In the presence of regurgitation, the difference in cardiac output between the left ventricle and ascending aorta yields the regurgitation volume. Regurgitation fraction is calculated by normalizing the regurgitation volume to the left ventricular stroke volume. Use of regurgitation fraction should be recommended as this parameter has the advantage to be relatively insensitive to concomitant other valve abnormalities. Regurgitation fraction limits for mitral and aortic regurgitations have been estimated by using cardiac MRI: mild ≤ 15%; moderate 16-25%; moderate-severe 26-48%; severe , 48%.. ...

Mitral Valve RegurgitationMitral Valve Regurgitation
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 ...

Proximal Isovelocity Surface Area (PISA) method for estimation of mitral regurgitation - All About Cardiovascular System and...Proximal Isovelocity Surface Area (PISA) method for estimation of mitral regurgitation - All About Cardiovascular System and...
Proximal Isovelocity Surface Area (PISA) method is based on the continuity equation. When a flow passes through a narrow orifice, as it approaches the narrowest region, there is a flow convergence and flow acceleration. PISA is the surface area of the hemisphere at the aliasing region of the flow convergence. PISA increases as the flow increases and also with lower aliasing velocity. To reduce errors in measurement, smaller aliasing velocity has to be set, to get higher PISA measurement with lower chance for errors.. Regurgitant flow rate can be calculated as:. 2 Pi r2 x Valiasing. Radius is measured from the orifice to point of colour change. If the flow convergence is not a true hemisphere, the angle subtended by the flow convergence at the orifice has to be measured and divided by 180 to get a correction factor. Good correlation between angiographic estimates of regurgitant flow and PISA based estimates have been reported.. ...

Mitral regurgitation resident survival guide - wikidoc
Mitral regurgitation (MR) is a disorder of the heart characterized by failure of the mitral valve to close properly during systole leading to blood leakage from the left ventricle to the left atrium during systole. Individuals with acute mitral regurgitation may present with significant hemodynamic instability due to the sudden drop in cardiac output, leading to acute pulmonary edema, hypotension and possible cardiogenic shock. Individuals with chronic compensated mitral regurgitation may be asymptomatic, with a normal exercise tolerance and no evidence of heart failure, or may present with fatigue, dyspnea on exertion, orthopnea, and paroxysmal nocturnal dyspnea.[1] The management of MR includes afterload reduction with careful monitoring of fluid status, management of the underlying disease (CAD, mitral valve prolapse, rheumatic heart disease), and early surgical intervention in severe cases. Ultimately, the management of MR depends on the anatomy of the mitral valve, the acuteness of the ...

Devices and methods are provided for diagnosing and repairing mitral valve defects such as mitral valve regurgitation. According to an exemplary method, mitral valve function is visualized by transesophageal echocardiography. 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

Papillary Muscle Dysfunction. | Annals of Internal Medicine | American College of PhysiciansPapillary Muscle Dysfunction. | Annals of Internal Medicine | American College of Physicians
Normal mitral valve function depends upon the maintenance of the proper spatial relationships between the papillary muscles, the chordae tendinae, and the mitral valve leaflets throughout the cardiac cycle. Papillary muscle dysfunction may occur as a result of (1) ischemia or infarction of a papillary muscle, (2) ventricular dilatation (including aneurysm), (3) rupture of a papillary muscle, (4) inflammatory disease of a papillary muscle, and (5) interventricular conduction disturbances.. Papillary muscle dysfunction results in mitral regurgitation and an apical systolic murmur. The characteristics of the murmur vary depending upon the etiology of the papillary muscle dysfunction. In the case of ...

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.

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

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 ...

Influence of Chronic Tethering of the Mitral Valve on Mitral Leaflet Size and Coaptation in Functional Mitral Regurgitation |...Influence of Chronic Tethering of the Mitral Valve on Mitral Leaflet Size and Coaptation in Functional Mitral Regurgitation |...
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 ...

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 ...

Valve repair for mitral insufficiency secondary to idiopathic juvenile polyarthritis. - Semantic ScholarValve repair for mitral insufficiency secondary to idiopathic juvenile polyarthritis. - Semantic Scholar
A female patient in whom idiopathic rheumatoid polyarthritis was diagnosed at the age of 8 years required surgery for severe mitral valve insufficiency 16 years later. Intraoperative analysis revealed a fibrotic endocarditis involving mainly the posterior leaflet. Granulomatous vegetations as well as a large thrombus which filled the left ventricular apex and simulated endomyocardial fibrosis were noted. Valve repair was achieved using an anterior leaflet augmentation with a patch of mitral homograft associated with a prosthetic ring annuloplasty. Postoperatively, a severe pericardial effusion required surgical drainage. Eight years later, the patient had no cardiac symptoms and echocardiography confirmed a normally functioning mitral valve.

Mitral Valve RegurgitationMitral Valve Regurgitation
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.. ...

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 ...

Finite Element Modeling of Mitral Valve Repair | Journal of Biomechanical Engineering | ASME DCFinite Element Modeling of Mitral Valve Repair | Journal of Biomechanical Engineering | ASME DC
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.. ...

Traditionally, in patients with mitral regurgitation (MR) a successful mitral valve repair is considered when residual MR by post-pump transesophageal echocardiography (TEE) is less than moderate or absent. Little is known about the prognostic value of less than moderate (mild or mild-to-moderate) residual MR for the early outcome of patients treated with mitral valve repair. Eligible for this study were patients undergoing isolated mitral valve repair. Patients with moderate or severe residual MR after valve repair were excluded. The primary endpoint of the study was the composite of death or need of reintervention. A total of 98 patients (54 with no residual MR-Group 1, and 44 with less than moderate residual MR-Group 2) were analyzed. Of these, 72% presented with New York Heart Association (NYHA) 3/4, and 38% were women. The primary endpoint of the study occurred in 3 (5.5%) patients in Group 1 and 6 (13.6%) patients in Group 2 MR (P = 0.31). There was a trend toward a higher incidence of use of

Minimally Invasive Mitral Valve Surgery: The Evidence | CTSNetMinimally Invasive Mitral Valve Surgery: The Evidence | CTSNet
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 ACC/AHA 1998 guidelines for the management of patients with valvular heart disease do not provide recommendations for patients who have undergone a mitral valve repair and neither do the ACCP guidelines of 2004. The European Society of Cardiology do provide guidelines for these patients, stating that there are no randomized controlled trials to support the safety of omitting warfarin after mitral repair. They recommend 3 months of warfarin at a target INR of 2.5 or 3.0 if there are additional risk factors. They acknowledge that this is based on expert consensus and acknowledge that many surgeons do not follow this guideline. Vaughan et al in a survey of UK surgeons found that 64% of consultants used warfarin post mitral repair, thus demonstrating that there is much variation in the anticoagulation management of patients post mitral repair in the UK.

Superiority of mitral valve repair was seen across all subgroups analyzed..

Many times a cardiologist refers just to the surgeon he knows and this might not be the right approach, he said.

MitraClip - WikipediaMitraClip - Wikipedia
MitraClip (mitral clip) is a novel, percutaneous method of heart treatment that is targeted for patients who have been denied surgery to fix mitral valve regurgitation. MitraClip was first implanted in 2003, and in 2013 became the FDAs first commercially approved alternative to mitral valve regurgitation surgery. Open-heart surgery is the standard method of treatment for patients with mitral valve regurgitation, however it is very invasive and not a feasible option for all patients. The risk of complications and mortality greatly increase in patients with other health conditions like liver disease, previous chest surgeries, and age above 75, which is why they are often denied surgery. The implantation of MitraClip via catheter does not involve open-heart surgery, but mimics the surgical method of edge-to-edge valve repair. The mitral valve leaflets are clipped together with the device instead of being sutured together, making this procedure much less invasive but still effective for improving ...
