Successful surgical repair of truncus arteriosus with interrupted aortic arch in infancy by an anterior approach

Abstract

A 98-day-old infant was successfully operated on for truncus arteriosus (type I) with interrupted aortic arch (type B) using a one-stage anterior approach. The interrupted aortic arch was reconstructed by direct anastomosis between the ascending and descending aorta. The ventricular septal defect was closed, and a 12-mm porcine valved conduit was placed on the right side of the ascending aorta to establish continuity between the right ventricle and pulmonary artery. Surgical procedures for the repair of this malformation are the focus of discussion.
