In idiopathic dilated cardiomyopathy, echocardiographic recordings of the proximal flow convergence region during mitral regurgitation (MR) have demonstrated a distinct biphasic pattern of flow and orifice area variation--a decrease during left ventricular contraction, an increase during ventricular relaxation. Schwammenthal et al hypothesized that the pattern of regurgitant orifice area variation in ischemic MR due to inferoposterior wall motion abnormalities will be similar, because the observed geometric substrate of regurgitation--apical tenting of the mitral valve--suggests a similar mechanism.
