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 annular plane. A number of leaflet tethering parameters have been described (tenting height and area… CONTINUE READING
