RESUMO
We report our long-term results of apico-aortic conduit implantation in patients with isolated idiopathic hypertrophic subaortic stenosis. Between December 1977 and July 1983, apico-aortic prosthetic-valved conduits were implanted in 4 such patients (age range, 24–65 years) who had severe left ventricular hypertrophy and small left ventricular chambers. In this procedure, the distal end of the conduit was anastomosed to the ascending aorta in 3 patients and to the upper abdominal aorta in 1. Postoperative echocardiography showed relief of the left ventricle–aortic gradient and enlargement of the left ventricular chamber in all cases. One patient died of perioperative wound infection. One patient died of unnatural causes 13 years after the initial operation; in his case, the conduit was known to be occluded. Two patients are alive 15 and 19 years, respectively, after the initial operation.
