Ventricular Septal Rupture Following Myocardial Infarction: A Potentially Fatal Complication

Key Clinical Message Mechanical complications of acute myocardial infarction include ventricular septal rupture (VSR), free wall rupture, and ischemic mitral regurgitation. Postinfarction VSR is a rare but serious complication of myocardial infarction. VSR has a lower incidence in the era of new reperfusion therapies. However, clinicians should be aware of this potentially fatal complication as the mortality remains extremely high. Early diagnosis and treatment are the cornerstones of achieving a better outcome.
