A case of acute myocardial infarction after successful transcatheter closure of ventricular septal defect.

Congenital heart diseases can be treated without surgery through advances in interventional cardiology. Complications such as infection and thrombus formation may develop due to foreign materials used during these procedures. Paradoxical embolism is a rare complication of transcatheter closure of ventricular septal defect (VSD) and could be responsible for acute myocardial infarction. Herein, we present a case of coronary thrombosis in a 2-year-old patient with VSD, which was closed with the Amplatzer VSD device. Although extremely rare, it should be considered in the appropriate clinical setting.
