Abstract

Ischemic mitral regurgitation (IMR) is a functional problem, which results from ischemia of the ventricle. Except in the case of ischemic papillary muscle rupture, the mitral apparatus is anatomically normal and the regurgitation is solely caused by abnormal systolic motion of the ventricle, interfering with the normal closure physiology of the valve. This is an important precision as organic mitral valve disease can simply be concomitant to coronary artery disease: in this situation, the prognosis is usually much better than in IMR. To make the situation even more complex, IMR can aggravate a pre-existent organic disease. Precise echocardiographic diagnosis is therefore needed to distinguish the different components and consequences of the underlying disease process.
