Role of Transesophageal Echocardiography in Surgical Retrieval of Embolized Amplatzer Device and Closure of Coronary–cameral Fistula

摘要

Congenital coronary artery fistula is an uncommon anomaly. Transcatheter coil embolization or Amplatzer vascular plug device closure of fistula is often done in symptomatic patients with safe accessibility to the feeding coronary artery. Embolization of Amplatzer vascular plug device is rare. We report an 11-year-old male child who presented to us with increasing shortness of breath for 7 years. He had a history of Amplatzer vascular plug device closure of right coronary–cameral fistula 8 years back. Echocardiography demonstrated a dilated aneurysmal right coronary artery with turbulent jet entering into the right ventricle (RV) and device embolized into the left pulmonary artery (LPA). Cardiac catheterization eventually confirmed the diagnosis. Surgical closure of fistula and retrieval of device was done using cardiopulmonary bypass. Intraoperatively transesophageal echocardiogram helped in localizing fistula opening in the RV below the anterior leaflet of tricuspid valve, continuous monitoring to prevent further distal embolization of the device during surgical handling, and assessment of completeness of repair of the fistula and LPA following retrieval of the device.
