OBJECTIVE To describe a surgical procedure utilizing a malleable bovine pericardium ring in mitral valve repair and clinical and Doppler echocardiographic results. METHODS Thirty-two (25 female and 7 male) patients, aged between 9 and 66 (M=36.4+/-17.2) years, were studied over a 16-month period, with 100% follow-up. In 23 (72%) of the patients, the mitral approach was the only one applied; 9...

BACKGROUND Mitral valve repair is the standard therapy for patients with severe mitral regurgitation. Currently, robotic mitral valve repair is the least invasive surgical approach and an alternative to the traditional sternotomy. Recent studies and newer guidelines on mitral valve repair advocate for earlier referral to surgery, resulting in better long-term outcomes of valve function and decr...

Introduction: Mitral valve insufficiency in adults is often a complication of ischemic heart disease. Coronary artery bypass grafting (CABG) is performed as a strategy for the treatment of coronary artery disease. The aim of this study was to evaluate mitral regurgitation (MR) before and after CABG. Materials and Methods: This Experimental study was condu...

Mitral valve reoperation, through a median sternotomy, for a patient with patent coronary bypass grafts is technically challenging and carries higher postoperative morbidity and mortality than a primary operation. We present a case of mitral valve repair using a beating heart technique under normothermic cardiopulmonary bypass that was performed 3 years after a coronary artery bypass operation....

Differentiation between primary and secondary forms of mitral regurgitation poses a frequent and important clinical problem. In the primary variety of mitral incompetence, there is distortion of the valve leaflets, rupture or redundancy of the chordae tendineae, or papillary muscle rupture. Heart failure, if present at all in such cases, is assumed to be a consequence of the large regurgitant v...

Introduction Functional mitral regurgitation (FMR) is a ventricular disease characterized by mitral valve insufficiency in the absence of structural abnormalities of the valve leaflets or sub-valvular apparatus.1 It commonly provokes heart failure and frequently confers an increase in patient mortality and morbidity. Medical therapy has a limited role for management of FMR. When treated, FMR is...

OBJECTIVE Based upon recent developments in transcatheter technology, this study was designed to evaluate the feasibility and haemodynamic performance of transcatheter valve-in-a-ring (VinR) implantation for potentially failed mitral repair using a minimally invasive, transatrial, off-pump approach. METHODS Adult sheep (54.3+/-3.0 kg) underwent mitral valve repair with a 26 mm complete annulo...

BaIlon mitral valvuloplasty and closed mitral valve conunissurotomy were performed in 450 and 127 patients, respectively. Also, 254 patients with severe mitral stenosis were enrolled in a prospective randomized trial comparing the two procedures. Immediately after balloon mitral valvuloplasty, mean left atrial pressure was 11.38±3.54 mmHg, transmitral valve gradient was 1.8±2 mmHg, and mit...

Retrospective examination of echocardiograms was performed in 34 patients with persistent atrioventricular (A-V) canal who had undergone cardiac catheterization. Characteristic findings in 16 patients with partial A-V canal were lack of continuity of mitral and tricuspid valves, paradoxical interventricular septal motion, definite E and A waves of the mitral valve anterior leaflet (MVAL) echoes...
