Supracristal Ventricular Septal Defect Complicated by Formation of an Aorto-Right Ventricular Outflow Tract Fistula: A Rare Cause of Biventricular Enlargement

Methodist Debakey Cardiovasc J. 2021 Jul 1;17(2):157-160. doi: 10.14797/PEFD1523. eCollection 2021.

Abstract

Aorto-right ventricular outflow tract fistulas typically occur secondary to trauma, infective endocarditis, and sinus of Valsalva aneurysm rupture. We describe an unusual case of a spontaneous aorto-right ventricular outflow tract fistula in the absence of such findings, instead forming secondary to a complicating supracristal ventricular septal defect and leading to dilated cardiomyopathy.

Keywords: cardiac magnetic resonance imaging; cardiology; congenital cardiac disease; congenital ventricular septal defect; congestive heart failure.
