BACKGROUND AND AIM OF THE STUDY A new mitral valve repair concept to treat mitral regurgitation (MR) due to valve prolapse was recently proposed. In this study, an improved design of this concept is presented, and the results of preliminary hemodynamic studies conducted in an in-vitro prolapse model are reported. METHODS The new repair approach is based on using a web/net attached to a standa...

We report the case of a patient with situs inversus totalis, annuloaortic ectasia complicated by aortic insufficiency and mitral regurgitation which induced congestive heart failure. Both valvular lesions were repaired physiologically using aortic root sparing Yacoub 'remodeling' technique and mitral ring annuloplasty. Valve sparing techniques can be used effectively even in patients with compl...

Acute unilateral pulmonary edema is an unusual clinical condition occasionally associated with severe mitral valve insufficiency. We describe a patient diagnosed as having unilateral pulmonary edema after an acute anterior myocardial infarction. Echocardiograms performed in the acute phase ruled out mitral insufficiency. A perfusion lung scan showed left-sided pulmonary hypoperfusion. The diagn...

We present a case of left ventricular pseudoaneurysm, which is a very rare and fatal complication of cardiac procedures such as mitral valve replacement. A 55-year-old woman presented to the Department of Thoracic and Cardiovascular Surgery at Hanyang University Seoul Hospital with chest pain. Ten years prior, the patient had undergone double valve replacement due to aortic regurgitation and mi...

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...

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...

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...
