Twenty-two @entity1 with @entity15202 were surgically treated between 1967 and July 1975. Five (23%) were under 1 year of age (group I) and 17 (77%) were between 2 and 24 years (group II). All @entity1 exhibited severe @entity712 and electrocardiographi (ECG) evidence of @entity4346 ( @entity4346 ) with strain pattern. In group II, angina was present in three cases, @entity1163 and fatigue in two; the ECG indicated @entity4346 in 10 cases (59%) with strain pattern in five (29%). A bicuspid aortic valve was present in 77% (17/22) of the cases; 32% had other @entity299 . Aortic valvotomy was performed on cardiopulmonary bypass in 20 cases, and with deep @entity2332 and @entity1167 in two. Three @entity1 under 1 month of age with associated anomalies died (hospital mortality 14%). Intraoperative average peak left ventricular-aortic systolic pressure gradient decreased from 86 to 21 mmHg (P less than 0.001). Late clinical (in all cases) and haemodynamic (26%) follow-up showed severe @entity256 in two @entity1 of group II; one of them had a second operation, the other one died three and a half years postoperatively. Results assessed on the basis of symptoms, ECG changes, aortic valve function, and/or haemodynamic findings were fair in the two surviving @entity1 . Results in group II were excellent in three, satisfactory in seven, fair in four, and poor in two cases. In @entity1 , aortic valvotomy is a palliative procedure which carries a high risk. In the older age group, early and late results are more gratifying.
