متن کاملQuantitative analysis of mitral valve morphology in mitral valve prolapse with real-time 3-dimensional echocardiography: importance of annular saddle shape in the pathogenesis of mitral regurgitation.
BACKGROUND Few data exist on the relation of the 3-dimensional morphology of mitral valve and degree of mitral regurgitation (MR) in mitral valve prolapse. METHODS AND RESULTS Real-time 3-dimensional transesophageal echocardiography of the mitral valve was acquired in 112 subjects, including 36 patients with mitral valve prolapse and significant MR (≥3+; MR+ group), 32 patients with mitral va...

متن کاملAnnular geometry in patients with chronic ischemic mitral regurgitation: three-dimensional magnetic resonance imaging study.
BACKGROUND Although animal studies showed that annular remodeling may be related to the pathogenesis of chronic ischemic mitral regurgitation (CIMR), little was known in humans. A better understanding of the precise 3D geometry of the mitral valvular-ventricular complex in CIMR is needed to devise a better surgical technique. The purpose of the study was to elucidate mitral annular geometry in ...
متن کاملMitral annular kinetics in mitral regurgitation
Methods Population: Patients with degenerative mitral regurgitation (n = 35) with normal LV EF pre and 12 months post mitral valve repair. Normal volunteers (n = 51). Image Acquisition: All participants underwent MRI on a 1.5T scanner (GE Healthcare) optimized for cardiac application. An ECG-gated, breath-hold steady state free precision technique was used to obtain 2 chamber and 4 chamber view...
