Coil Embolization and Left Ventricular Assist Device After Arterial Switch Operation

Aortopulmonary collateral arteries are frequently found in patients with transposition of the great arteries after catheterization. Although most of them are asymptomatic, it may cause heart failure or pulmonary hemorrhage after an arterial switch operation. Here we report a case of symptomatic aortopulmonary collateral arteries after arterial switch, which necessitated support with a centrifugal pump and left ventricular assistive device because of severe mitral regurgitation and left atrial hypertension and emergent coil embolization. Hemodynamics dramatically improved after embolization. The postoperative period was uneventful, and the infant was released from the hospital on the 14th day.

Automated summary

In patients with transposition of the great arteries, aortopulmonary collateral arteries are common after catheterization. This case report describes symptomatic aortopulmonary collateral arteries following arterial switch, which required support with a centrifugal pump and left ventricular assistive device, along with emergent coil embolization. After embolization, hemodynamics significantly improved, and the postoperative recovery was uneventful.
