Surgical repair of type II truncus arteriosus without a conduit.

A technique for reconstructing the right ventricular outflow tract in an infant with type II truncus arteriosus without using a prosthetic conduit is described. The truncal root is transected, and the confluence of branch pulmonary arteries is brought anterior to the aorta by using Lecompte's maneuver. The aorta is then reconstructed directly with an end-to-end anastomosis. The right ventricular outflow tract is reconstructed by anastomosing the posterior wall of the confluence directly to the apex of the vertical right ventriculotomy. A glutaraldehyde-preserved pericardial patch is then placed anteriorly to complete reconstruction of the right ventricular outflow tract.
