Aortopulmonary anastomosis in patients with levotransposition

A technique for approximating the right pulmonary artery to the aorta in levo (L) transposition is described. The anastomosis is placed high on the ascending aorta to avoid occluding the coronary circulation by the clamp during the anastomosis. It is in patients with occluded left side anastomoses or single right pulmonary arteries that the right-sided anastomoses are most useful in L-transposition.
