Abstract:
Mitral regurgitation (MR) is a frequent complication of myocardial infarction and coronary artery disease that is associated with adverse prognosis. The main mechanism of ischemic MR relates to distortion of the spatial relationships between the mitral valve and papillary muscles secondary to ventricular remodeling. The evidence that treatment of ischemic MR improves long-term survival still remains unclear, and further studies are needed to determine whether correcting ischemic MR will improve survival and/or symptoms.
