Acute Versus Chronic Ischemic Mitral Regurgitation: An Echocardiographic Study of Anatomy and Physiology [Original Articles]

Conclusions: Sudden-onset left ventricular dysfunction in acute MI may cause loss of coaptation of the MV even with a relatively mild degree of valve tethering. Compared with previously studied chronic IMR, a smaller leaflet area without leaflet adaptation and a larger hemodynamic burden at the acute onset of MI could result in clinically significant IMR despite relatively small leaflet tethering.
