[The surgical treatment of discrete subaortic stenosis (author's transl)].
The AA. examine their experience concerning 23 patients operated on for a discrete subaortic stenosis since 1969. Immediate results are satisfactory, even if there have been postoperative complications in 26% of the patients. Late results are less satisfactory, above all because of the progression of aortic insufficiency far from the operation. Date of literature are nor allowing valuable indications about the natural history of the patient after surgical treatment, because of the scarcity of postoperative hemodynamic controls and, especially, of serial examinations. The AA. believe, on the ground of considered data and personal experience, that it is prudent, awaiting for further critical evaluation of late results, to limit surgical indications, in asymptomatic patients, to cases with left ventricular-aortic gradient superior to 70 mmHg.
