Cardiac Valve Annuloplasty
Mitral Valve Annuloplasty
The valve between the left atrium and left ventricle of the heart.
Mitral Valve Insufficiency
Tricuspid Valve Insufficiency
Backflow of blood from the RIGHT VENTRICLE into the RIGHT ATRIUM due to imperfect closure of the TRICUSPID VALVE.
Heart Valve Prosthesis Implantation
Surgical insertion of synthetic material to repair injured or diseased heart valves.
Heart Valve Diseases
Heart Valve Prosthesis
The valve consisting of three cusps situated between the right atrium and right ventricle of the heart.
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.
Cardiac Surgical Procedures
Surgery performed on 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).
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.
Mitral Valve Prolapse
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.
Rheumatic Heart Disease
Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic.
Heart Valve Prolapse
Downward displacement of any one of the HEART VALVES from its normal position. This usually results in failed valve closure.
Striated muscle cells found in the heart. They are derived from cardiac myoblasts (MYOBLASTS, CARDIAC).
Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues using a transducer placed in the esophagus.
The innermost layer of the heart, comprised of endothelial cells.
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)
A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).
Echocardiography, Doppler, Color
A conical fibro-serous sac surrounding the HEART and the roots of the great vessels (AORTA; VENAE CAVAE; PULMONARY ARTERY). Pericardium consists of two sacs: the outer fibrous pericardium and the inner serous pericardium. The latter consists of an outer parietal layer facing the fibrous pericardium, and an inner visceral layer (epicardium) resting next to the heart, and a pericardial cavity between these two layers.
The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).
Aortic Valve Prolapse
The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.
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.

The Growing Clinical Importance of Secondary Tricuspid Regurgitation | JACC: Journal of the American College of Cardiology
With prosthetic ring annuloplasty (Fig. 5B), the annulus is permanently fixed in a systolic position by suturing in a rigid or semirigid ring (51).. Recent long-term studies have suggested that prosthetic ring annuloplasty repair is more durable than suture repair and confers significant improvements both in overall and event-free survival. In many series, freedom from moderate or severe TR 10 years after surgery is ,85% for patients who underwent ring annuloplasty (8,52).. The goal of reconstructive valve surgery is to preserve leaflet mobility and to create a large surface of coaptation, while preventing further annular dilation.. The most widely used prosthetic rings in surgical practice are currently the Carpentier-Edwards annuloplasty ring (Edwards Lifesciences LLC, Irvine, California), the flexible band Cosgrove-Edwards annuloplasty system (Edwards Lifesciences, LLC), and the Edwards MC3 ring system (Edwards Lifesciences, LLC).. The Carpentier-Edwards ring has been the repair device of ...

Patent US6416548 - Antimicrobial annuloplasty ring having a biodegradable insert - Google Patents
This invention provides an antimicrobial annuloplasty rings, and methods for making the same, wherein the annuloplasty rings have a desired degree of initial rigidity to facilitate ease of handling during implantation but which becomes flexible some time after implantation. The annuloplasty ring contains a relatively rigid insert enclosed by a fabric sheath, the insert being at least partly comprised of a biodegradable material. Following surgical implantation of the annuloplasty ring, the rigid insert component of the ring, upon exposure to blood and/or other physiological fluids, undergoes a controlled biodegradation which decreases its rigidity, thereby increasing the flexibility of the implanted annuloplasty ring. Furthermore, at least some portion of the annuloplasty ring of the invention has incorporated therein one or more antimicrobial agents in a manner which reduces the likelihood of device infection following implantation.

BJCVS, Vol.: 31 Ed.: 6 - 449/453 - 2016, Low Cost Simulator for Heart Surgery Training
To train closure of atrial septal defect, the same mitral support is used. After the patch suturing exercise, a tricuspid annuloplasty may be subsequently performed using the same model (around the sutured patch).. The trainee alone, under supervision of a senior surgeon, did most exercises. Some exercises needed the help of an assistant who was the senior surgeon or another trainee. There by, each thoracotomy simulator was individual, but could be used to train surgeon and first assistant surgeon simultaneously.. RESULTS. At our service, training was carried out by means of bench exercises, totaling nearly 22 hours, with supervised exercises every fortnight. Those exercises were later repeated at home or anywhere else, since every resident received an off-laboratory kit to use. The minimum amount of repetitions was set on the basis of exercise difficulty level. From the minimum amount of required exercises, we then calculated the total consumables used (Table 2).. There was training on ...

Does lowering pulmonary arterial pressure eliminate severe functional tricuspid regurgitation? | JACC: Journal of the American...
The principal finding of this study is that after reduction in PA systolic pressures after PTE, severe TR improved significantly in 70% of patients, often despite persistent tricuspid annular dilation. However, 30% of patients manifested persistent severe TR and had a lower PA pressure reduction. Persistent severe TR and less effective PA pressure reduction were more frequently associated with distal thromboembolic disease, but such distinction could not be identified by any clinical, echocardiographic, or hemodynamic parameters preoperatively. This study suggests that the resolution of severe functional TR, without tricuspid valve annuloplasty, is related to the reduction of pulmonary hypertension. The major postoperative feature that identified resolution of severe TR was a more significant improvement of pulmonary hypertension (Fig. 1).. Whether TR will improve after surgery for a left-sided valvular defect may depend on success of surgical intervention, severity of baseline pulmonary ...

Abstract 3456: Reversal of Severe Tricuspid Regurgitation after Pulmonary Endarterectomy is due to Right Ventricular Reverse...
Background: Severe functional tricuspid regurgitation (TR) is a hallmark of chronic thrombo-embolic pulmonary hypertension (CTEPH), yet little is known about the natural history of TR after relief from CTEPH. We sought to assess early- and late-term tricuspid function after pulmonary endarterectomy (PEA) and to associate it with the reversal of right ventricular (RV) morphological and functional changes induced by CTEPH.. Material and Methods: From December 2000 to March 2006, 90 patients underwent PEA. Type and grade of TR and end-diastolic eccentricity index were studied by echo. RV tele-diastolic and tele-systolic volumes and RV ejection fraction were measured by cardiac MR. Hemodynamic variables were obtained through right heart catheterization. Patients with a full set of pre-operative data (n=66) were studied pre-discharge, then at 3 months, 1 and 3 years post-operatively.. Results: After PEA, mortality rate was 4.5%. Hemodynamic recovery was immediate (Table⇓). TR dramatically improved ...

Patent US7993396 - Mitral valve annuloplasty ring having an offset posterior bow - Google Patents
A mitral heart valve annuloplasty ring having a posterior bow that conforms to an abnormal posterior aspect of the mitral annulus. The ring may be generally oval having a major axis and a minor axis, wherein the posterior bow may be centered along the minor axis or offset in a posterior section. The ring may be substantially planar, or may include upward bows on either side of the posterior bow. The ring may include a ring body surrounded by a suture-permeable fabric sheath formed of a plurality of concentric ring elements or bands. The posterior bow is stiff enough to withstand deformation once implanted and subjected to normal physiologic stresses. A method of repairing an abnormal mitral heart valve annulus having a depressed posterior aspect includes providing a ring with a posterior bow and implanting the ring to support the annulus without unduly stressing the attachment sutures.
Transvenous right ventricular pacing in a patient with tricuspid mechanical prosthesis | Journal of Cardiothoracic Surgery |...
A 66 year-old woman was admitted to our hospital, because she had an episode of cardiovascular collapse requiring cardiopulmonary resucitation four days after cardiac operation in other hospital. The patient had previously undergone one closed and three open heart procedures. The first operation was a closed mitral surgery by a left thoracotomy. After nine years she needed new surgery because she had mitral stenosis and a mitral comisurotomy was done throught a sternotomy and under cardiopulmonary bypass. Ten years after the second operation, because she had mitral stenosis with extensive calcification of the anterior leaflet and aortic and tricuspid regurgitation, a double mitro-aortic valve replacement was done with two Bjork- Shiley (Shiley Inc - Irvine. CA, USA) prostheses. Also a De Vega tricuspid annuloplasty was performed. In 2002 symptoms of congestive heart failure, dyspnea and severe tricuspid insufficiency necessitated replacement of the tricuspid valve by a CarboMedics Prosthesis ...
Reversible TR in Acute and Chronic Cardiomyopathy | JACC: Cardiovascular Imaging
Functional tricuspid regurgitation (TR) has been considered worthy of repair because of its possible impact on clinical outcomes (1,2). Nonetheless, no consensus has been reached on the indications and timing of surgeries. Also, the accurate assessment of TR severity remains challenging. In the July 2012 issue of iJACC, Ling et al. (3) provided very helpful information on the evaluation of TR and right ventricular (RV) dysfunction. In Case 1, they discussed TR in the setting of left ventricular (LV) dysfunction and mitral regurgitation (MR). We hope to point out that significantly reversible TR could occur in patients with both chronic and acute cardiomyopathies, with or without MR, which needs special attention before treatment decisions are made.. Case 1, a 53-year-old woman with diabetes and dyslipidemia, developed new-onset heart failure. Cardiac catheterization ruled out ischemia. Echocardiography revealed decreased LV ejection fraction (LVEF: 11%), severe MR/TR, and dilated tricuspid valve ...
Pesquisa | Portal Regional da BVS
BACKGROUND: Pulmonary hypertension (PH) is a common cause of right ventricular (RV) remodeling and functional tricuspid regurgitation (FTR), but incremental pulmonary artery systolic pressure (PASP) does not always correlate with anatomic and functional RV changes. This study aimed to evaluate a noninvasive measure of pulmonary vascular resistance (PVR) for predicting RV dilatation, RV dysfunction, and severity of FTR. METHODS: We prospectively analyzed consecutive stable patients with PASP ≥ 35 mm Hg or any degree of RV dilatation or dysfunction secondary to PH. Noninvasive PVR was calculated based on FTR peak velocity and flow in RV outflow tract. RESULTS: We included 251 patients, aged 72.1 ± 11.4 years, 53% women, 74.9% with type 2 pulmonary hypertension. The mean PASP was 48.3 ± 12.2 mm Hg. Both PASP and PVR significantly correlated with FTR, RV dilatation, and RV systolic dysfunction. After dichotomizing FTR and RV dilatation and systolic dysfunction as nonsignificant vs significant, ...

N2 - Objectives: To define the durability of aortic valve repair (AVR ep) and the effect of surgical timing on late survival. Methods: From June 1986 to June 2011, 331 patients underwent elective AVRep for aortic regurgitation (mean age, 53 ± 17 years; 76% men). The repair methods included commissuroplasty (n = 270; 81%), triangular resection and plication (n = 106; 32%), resuspension or cusp shortening (n = 102; 31%), and perforation closure (n = 23; 7%). Results: In-hospital mortality was 0.6% (2 of 332). Four patients (1%) experienced early repair failure; two underwent repeat repair. Overall survival was 91% and 81% at 5 and 10 years, respectively. After adjusting for age, greater left ventricular ...

Internet Scientific Publications
While early-onset TR following mitral valve surgery may reflect a variety of underlying causes (persistent pulmonary hypertension, mitral prosthetic dysfunction, progressive aortic valve disease or left ventricular failure), late-onset TR usually reflects intrinsic RV dysfunction and/or tricuspid annular abnormalities. Functional tricuspid insufficiency has been reported in up to 67% of those undergoing left heart surgery and is thought to be from the effects of transmitted afterload.[17,18,19] While conservative management of TR was initially advocated due to expected improvements in functional regurgitation after left-sided surgery, it is now generally accepted that symptoms of right heart failure, and exercise intolerance, will persist in a significant number of patients. Groves compared the clinical and echocardiographic characteristics of 26 patients with and without late-onset TR after mitral valve surgery; between groups, doppler-estimated PAPs were similar and there was ...

Features & the Future - Radeon RX Vega Unveiled: AMD Announces $499 RX Vega 64 & $399 RX Vega 56, Launching August 14th
Fifth, AMD is tweaking their boost clock mechanism and how its advertised. Up until now, the boost clock was the maximum clock a Radeon card would hit. e.g. a stock Fury X topped out at 1.05GHz, and a stock RX 580 at 1340MHz. Starting with Vega RX, however, the companys definition of the boost clock is changing to the highest clockspeed a card is guaranteed to hit, but not the absolute highest clockspeed it can hit under load. There are still some nuances I want to test once I have the hardware in-hand, but at first glance this sounds closer to NVIDIAs definition, where each and every card is allowed to reach its natural limit (for the stock voltage).. Finally, while AMD didnt clarify exactly when this change was made, the company has tweaked their Freesync Low Framerate Compensation technology to work with monitors that have a 2x range between min and max refresh rates, as opposed to 2.5x at launch. Im told that 2.5x (or better) is still the ideal range, but it now works at 2x. This is an ...

First Linksday of 2014 | Laurie Toby Edison
Research shows that loyal customers often get upset when a brand commonly associated with men expands to include products perceived as feminine-especially in cases where men use a particular brand to communicate their own identities. Harvard Business School Senior Lecturer Jill J. Avery calls this phenomenon gender contamination. …. Avery recalls her experience running the womens shaving brand at Gillette. The company made a point of building products from the ground up for the distinct hair removal needs of both men and women. But it also made a point of creating a different brand name for Gillettes products for women. Not to put too fine a point on it, Gillette called the brand Gillette for Women. Having a line that was distinctively marked for women protected male Gillette users from the feminization of their brand, Avery says.. Lots more data at the link.. ***. On a more serious note, we missed it in November when Chauncey de Vega at We Are Respectable Negroes deconstructed the ...

- Between 2006 and 2012, a total of 1424 aortic valve procedures were performed at our institution, comprising aortic valve replacement with/without replacement of the ascending aorta, aortic valve-sparing procedures and Ross procedures. (biomedcentral.com)
- The aortic valve separates the left ventricle from the aorta - the main artery of the body. (mercy.com)
- Cardiac output is the amount of blood ejected by the left ventricle in one minute. (omicsonline.org)
- Cardiac output (CO) is the volume of blood being pumped by the heart, by left ventricle in the time interval of one minute. (omicsonline.org)
- After the left atrium fills with blood, the mitral valve allows blood to flow from the left atrium into the heart's main pumping chamber called the left ventricle . (academic.ru)
- The mitral valve separates the left atrium from the left ventricle and guarantees unidirectional blood flow from the first to the second chamber. (royalsocietypublishing.org)
