Dynamic Change of Ischemic Mitral Regurgitation in a Patient with Acute Coronary Syndrome

Abstract

Ischemic mitral regurgitation (IMR) is commonly known as a chronic complication of left ventricular remodeling due to coronary artery disease. Acute IMR after coronary artery disease, such as acute myocardial infarction particular, could also develop as a mechanical complication involving papillary muscle rupture. However, the clinical significance of acute transient IMR and the therapeutic intervention in coronary artery disease is infrequently reported. We describe a patient with acute pulmonary edema due to acute IMR, which resolved immediately after coronary revascularization.
