Anterolateral Papillary Muscle Rupture After Acute Myocardial Infarction Leading to Severe Mitral Regurgitation: A Case Report
Due to dual blood supply, ischemic mitral anterolateral papillary muscle rupture is less common than that of posteromedial papillary muscle and is rare in acute myocardial infarction without left main lesion. "Pseudo-normalization" phenomenon of left ventricular ejection fraction may occur in the early stage, which is inconsistent with clinical symptoms.
