repair of the mitral valve is the treatment of choice for mitral valve regurgitation when the anatomy is favorable. it is well known that mitral valve repair enjoys better clinical and functional results than any other type of valve substitute. this fact is beyond doubt regardless of the etiology of the valve lesion and is of particular importance in degenerative diseases. this review analyzes ...

background: conventional doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (lvedp). however, these parameters have limitations in predicting lvedp among patients with mitral regurgitation. this study sought to establish whether the correlation between measurements derived from tissue doppler echocardiography and...

background: percutaneous balloon mitral valvotomy (bmv) is the gold standard treatment for rheumatic mitral stenosis (ms) in that it causes significant changes in mitral valve area (mva) and improves leaflet mobility. development of or increase in mitral regurgitation (mr) is common after bmv. this study evaluated mr severity and its changes after bmv in iranian patients. methods: w e prospecti...

background: several competing geometric and hemodynamic factors are suggested as contributing mechanisms for functional mitral regurgitation (mr) in heart failure patients. we aimed to study the relationships between the severity of mr and the qrs duration and dyssynchrony markers in patients with ischemic or dilated cardiomyopathy. methods: w e prospectively evaluated 251 heart failure patient...

background: left ventricular (lv) twist is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of lv function. we sought to assess the impact of chronic pure mitral regurgitation (mr) on the torsional mechanics of the left human ventricle using tissue doppler imaging. methods: nineteen severe mr patients with a normal lv ejection fraction and 16 non-...

The causes of mitral valve insufficiency may largely be divided into two categories: organic or primary and functional or secondary. In the first case, the cause of insufficiency is due to a morphological change of the valve. Numerous diseases may damage the valve. Of the degenerative disease we may list myxomatous degeneration, fibroelastic deficiency or annular calcifications. Of the phlogist...

global myocardial ischemia and ischemia-reperfusion injury are potential adverse events related with cardioplegic arrest. beating heart surgery has avoided such complications and adapted to valve surgery following successful results published on myocardial revascularization. difficulty in weaning from cardiopulmonary bypass may be lessened by using on-pump beating heart surgery for mitral valve...

background: ischemic mitral regurgitation (imr) is a common complication after acute myocardial infarction (ami). we aimed to investigate the frequency of imr following first-time ami and its association with infarct location, in-hospital mortality, and complications. methods: from september 2011 to november 2012, all patients with a diagnosis of first-time acute st-elevation mi were enrolled i...

OBJECTIVE To study mitral valve function in the postoperative period after correction of the partial form of atrioventricular septal defect. METHODS Fifty patients underwent surgical correction of the partial form of atrioventricular septal defect. Their mean age was 11.8 years and 62% of the patients were males. Preoperative echocardiography showed moderate and severe mitral insufficiency in...

Double orifice mitral valve (DOMV) is an uncommon congenital heart defect. The isolated occurrence of this anomaly is very rare and, more often, is associated with another congenital malformation, dominated by atrioventricular canal defects (AVCD). Mitral insufficiency and/or stenosis may complicate this malformation. Treatment may be summarized as abstention, surgical valve repair, or valve re...
