BACKGROUND This study was undertaken to compare mitral valve repair and replacement as treatments for ischemic mitral regurgitation (IMR) with left ventricular dysfunction (LVD). Specifically, we sought to determine whether the choice of mitral valve procedure affected survival, and discover which patients were predicted to benefit from mitral valve repair and which from replacement. METHODS ...
In this report, we present 34 patients in whom surgical intervention was undertaken for severe mitral insufficiency due to mitral valve prolapse (MVP). Location and severity of MVP and regurgitation were assessed preoperatively by live/real time three-dimensional transthoracic echocardiography and closely agreed with the surgical findings.
To investigate the mechanism that increases the orifice area of the mitral valve during balloon dilatation 43 surgically excised intact rheumatic mitral valves were studied. The main pathological features were (a) fibrosis of mitral valve leaflets and commissures (10 valves); (b) fibrosis with calcification of one commissure (eight anterolateral, seven posteromedial); (c) fibrosis with calcific...
pure or predominant mitral stenosis before and 34 to 40 months after valvotomy. The patients were divided into 3 groups: pure mitral stenosis without increased pulmonary vascular resistance (group I, n =33), pure mitral stenosis with abnormal increase of pulmonary vascular resistance (group II, n= I2), and predominant mitral stenosis with mild insufficiency (group III, n= 9; all patients underg...

BACKGROUND We aimed to compare the outcomes of mitral valve repair with flexible band (FB) versus complete semirigid ring (SR) in degenerative mitral valve disease patients. METHODS From September 2011 to 2014, 171 patients were randomized and underwent successful mitral valve repair using a SR (n = 85) or FB (n = 86). There were no significant between-group differences at baseline. RESULTS...
Marfan syndrome is a systematic genetic disease of the connective tissue. The cardiac affection would predict the prognosis and ischemic stroke might complicate it. The purpose of this work is to discuss the mechanisms of the ischemic stroke in Marfan syndrome which have to be considered in all young patients of ischemic strokes. We report the case of a 17-year-old male patient who presented wi...
OBJECTIVE Anatomic alterations of the mitral valve such as increased mitral leaflet area, length and laxity, and anterior displacement of the papillary muscles in hypertrophic obstructive cardiomyopathy predispose patients to residual systolic anterior motion and persistence of outflow obstruction and mitral regurgitation after septal myectomy. We investigate the long-term results of combined a...
M itral valve repair was first suggested in 1902 by Sir Thomas Brunton (1) as a surgical approach to patients with rheumatic mitral valve disease. However, it was not until after the introduction of the heart-lung machine in 1953 by Gibbons (2) that techniques for the repair of pure mitral valve regurgitation were first introduced by Lillehei et al. (3) in 1957. Because of the development of pr...
