Repair of aortico-left ventricular tunnel associated with subpulmonary obstruction

Abstract

Aortico-left ventricular tunnel is a rare congenital cardiac defect. Because the tunnel traverses the upper portion of the interventricular septum, the potential exists for an aneurysmal tunnel to obstruct the outflow of the right ventricle. We report our clinical experience with such a patient, and emphasize the importance of a two-patch technique to avoid its occurrence.
