Pulmonary autograft: an American experience.

Pulmonary valve autograft replacement of the aortic valve has been performed in nine patients in an effort to duplicate in the United States the experience of Sir Donald Ross in London. Four male and five female patients ranging in age from seven to thirty-four years have been operated on for indications of aortic stenosis in six and aortic regurgitation in three. Three patients had associated procedures performed concomitantly. All patients survived the surgery and were clinically improved, however, one patient did require reoperation for progressive aortic insufficiency. Specific indications, results, and technical considerations are discussed and illustrated.
