Acute mitral regurgitation due to leaflet tear after balloon valvotomy.
Percutaneous mitral balloon valvotomy (PMV) has evolved into an effective method for the treatment of patients with symptomatic mitral stenosis. An increase in mitral regurgitation can occur in '45% of patients undergoing PMV. Severe mitral regurgitation can be caused by rupture of chordae or of a papillary muscle. Noncommissural tearing of the mitral leaflet is also an important mechanism of s...
متن کاملSudden death in mitral regurgitation due to flail leaflet.
OBJECTIVES We sought to assess the incidence and determinants of sudden death (SUD) in mitral regurgitation due to flail leaflet (MR-FL). BACKGROUND Sudden death is a catastrophic complication of MR-FL. Its incidence and predictability are undefined. METHODS The occurrence of SUD was analyzed in 348 patients (age 67 +/- 12 years) with MR-FL diagnosed echocardiographically from 1980 through ...
متن کاملmitral regurgitation after percutaneous balloon mitral valvotomy in patients with rheumatic mitral stenosis: a single-center study
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...
متن کاملMitral regurgitation following mitral balloon valvotomy. Differing mechanisms for severe versus mild-to-moderate lesions.
BACKGROUND This study was designed to evaluate the incidence and mechanisms of mitral regurgitation following mitral balloon valvotomy (MBV) in 40 consecutive patients with symptomatic tight pliable mitral stenosis. METHODS AND RESULTS Transthoracic echocardiography with color flow mapping was performed before and 24 hours after the procedure. Patients who developed significant mitral regurgi...
