Technique for repair of single-ventricle hearts with transposition of the great arteries and aortic arch hypoplasia

We describe a modified technique of aortopulmonary anastomosis for palliative repair of hearts with a single left ventricle, a rudimentary right ventricle, transposition of the great vessels, and a hypoplastic aortic arch. This procedure creates an unobstructed left ventricular outflow tract and avoids the problems of spiral patch grafting and multiple patch enlargements of the ascending aorta and arch.
