Damus-Stansel-Kaye procedure: technical modifications.

The Damus-Stansel-Kaye procedure has been applied for the relief of outflow tract obstruction caused by a restrictive bulboventricular foramen or subaortic stenosis in patients with complex univentricular heart disease. The procedure may also be part of a biventricular repair of a Taussig-Bing transposition of the great arteries. This report details technical modifications of the procedure to ensure unobstructed blood flow from the pulmonary artery to the aorta and to maintain the integrity of the pulmonary and aortic valves.
