Septal-lateral annular cinching abolishes acute ischemic mitral regurgitation.
OBJECTIVE Ring annuloplasty prevents acute ischemic mitral regurgitation in sheep, but it also abolishes normal mitral annular and posterior leaflet dynamics. We investigated a novel surgical approach of simple septal-lateral annular cinching with sutures to treat acute ischemic mitral regurgitation. METHODS Nine adult sheep underwent implantation of multiple radiopaque markers on the left ve...
متن کاملAnnular versus subvalvular approaches to acute ischemic mitral regurgitation.
BACKGROUND Ischemic mitral regurgitation (IMR) has been attributed to annular dilatation, papillary muscle (PM) displacement ("apical leaflet tenting"), or both. We compared the efficacy of reducing annular or subvalvular dimensions to gain more mechanistic insight into acute IMR. METHODS Eight adult sheep underwent implantation of radiopaque markers on the LV, mitral annulus (MA), each leafl...
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 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...
متن کاملEffects of paracommissural septal-lateral annular cinching on acute ischemic mitral regurgitation.
BACKGROUND Previous experimental studies demonstrated that central septal-lateral (SL) annular cinching (SLAC) abolishes acute ischemic mitral regurgitation (IMR), but whether localized cinching near the anterior (ACOM) or posterior (PCOM) commissure is equally effective is unknown. METHODS Six adult sheep underwent implantation of 9 radiopaque markers on the left ventricle, 8 around the mitr...
