Active adaptation of the tethered mitral valve: insights into a compensatory mechanism for functional mitral regurgitation.
BACKGROUND In patients with left ventricular infarction or dilatation, leaflet tethering by displaced papillary muscles frequently induces mitral regurgitation, which doubles mortality. Little is known about the biological potential of the mitral valve (MV) to compensate for ventricular remodeling. We tested the hypothesis that MV leaflet surface area increases over time with mechanical stretch...
متن کاملMechanistic insights into ischemic mitral regurgitation: echocardiographic and surgical implications.
Ischemic mitral regurgitation is a common complication of the healing phase of myocardial infarction. A number of mechanisms have been invoked in its pathogenesis, including alterations of papillary muscle position, annular dynamics, and intraventricular synchrony. The echocardiographic hallmark of ischemic mitral regurgitation is systolic tethering of the mitral valve leaflets away from the an...
متن کاملChronic ischemic mitral regurgitation: insights into Pandora's box.
Chronic ischemic mitral regurgitation (cIMR) remains a vexing problem for a large number of patients and their respective clinicians. It is estimated that 2 million Americans experience cIMR, and this number is likely to increase with an aging general population and improved survival rates for myocardial infarction.1 Despite the large number of patients with this disease, relatively few patient...
متن کاملNovel Mechanistic Insights Into Atrial Functional Mitral Regurgitation - 3-Dimensional Echocardiographic Study.
BACKGROUND Left atrial remodeling caused by persistent atrial fibrillation (AF) causes atrial functional mitral regurgitation (MR), even though left ventricular (LV) remodeling and organic changes of the mitral leaflets are lacking. The detailed mechanism of atrial functional MR has not been fully investigated. METHODSANDRESULTS Of 1,167 patients with AF who underwent 3D transesophageal echoc...
متن کاملMechanisms of atrial mitral regurgitation: insights using 3D transoesophageal echo.
AIMS Functional mitral regurgitation (FMR) is a consequence of mitral annular enlargement, leaflet tethering and reduced co-aptation. The importance of the left atrium (LA) as a cause of mitral regurgitation (MR) is less clear. We applied a co-aptation index using three-dimensional (3D) transoesophageal echocardiography to FMR and MR secondary to LA dilatation (atrial mitral regurgitation, AMR)...
