Abstract:
We here report the case of a 67-year-old woman with moderate mitral regurgitation without significant structural abnormalities that get worse during severe recurrent heart failures and preserved ejection fraction with concomitant paroxysmal atrial fibrillation. Atrial fibrillation became permanent and despite a well-controlled cardiac frequency, new heart failure episodes occurred. Exercise doppler echocardiography showed that the mechanism of this mitral regurgitation was a two leaflet mitral tenting. We discuss here the different mechanisms that could induce these kinds of mitral regurgitation with excessive tenting. We emphasize the interest of early detection by exercise doppler echocardiography even when a triggering factor like atrial fibrillation seems to be involved. We also discuss the interest of mitral valve replacement for these patients.
