Echocardiographic studies of the mitral valve were performed in 57 patients with pure or predominant mitral stenosis who subsequently underwent surgery (30 commissurotomy, 27 valve replacement). Mitral valve calcification was graded heavy (thick, conglomerate echoes), light (multiple, discrete linear echoes) or none (thin, single or duplicate signals). Valve mobility, measured as the excursion ...
OBJECTIVES The aim of this study was to examine 1-year outcomes of transseptal balloon-expandable transcatheter heart valve implantation in failed mitral bioprosthesis, ring annuloplasty, and mitral annular calcification (MAC). BACKGROUND Immediate outcomes following transseptal mitral valve implantation in failed bioprostheses are favorable, but data on subsequent outcomes are lacking. MET...
INTRODUCTION Fungal prosthetic valve endocarditis (PVE) is rare but serious complication of valve replacement surgery. Candida species, particularly Candida albicans is the most common isolated pathogen in fungal PVE (1-6%of cases). CASE PRESENTATION We describe a 35-year-old woman who underwent mechanical mitral valve replacement about 3 years ago. She was admitted with neurological symptoms...
In cases of old myocardial infarction, the presence of mitral valve regurgitation is one of the predicting factors of long-term prognosis. The mechanism of ischemic mitral regurgitation consists of mitral annular dilatation, left ventricular (LV) dilatation followed by tethering of the mitral valve, etc. Since long-term prognosis of the patients in whom the degree of mitral valve regurgitation ...
Objective: Evaluate the efficacy of the extended vertical transseptal approach in mitral valve reoperation with a small left atrium. Method: From January 2001 to December 2002, 15 patients with previous mitral operation, small left atrium and atrial fibrillation underwent mitral valve surgery through an extended vertical transseptal incision. There were nine women and six men. Their ages ranged...
Open heart surgery has been performed at the Massachusetts General Hospital in 13 patients less than 6 months after the initiation of treatment for acute or subacute bacterial endocarditis. The endocarditis involved the aortic valve in 12 cases and a mitral valve prosthesis in the other. In two patients there was concomitant rupture of chordae tendineae of the mitral valve. One patient received...
Minimally invasive mitral valve surgery (MIMVS) was introduced in the mid-1990s to refer to a variety of surgical techniques that avoid full sternotomy through smaller or alternative chest wall incisions, as an attempt to reduce complications, but at the same time preserve outcomes of the full sternotomy approach. In this review, different aspects of MIMVS are discussed in relation to its appro...
Mitral valve surgery has changed with the wide acceptance of mitral valve repair. The aim of this study is to obtain the long-term results of patients who underwent mitral valve replacement (MVR) using a biological prosthesis in contemporary practice in Japan. From January 1990 to December 2013, 76 patients underwent MVR using a biological prosthesis with or without concomitant surgery. Data we...
