Between 1966 and 1979 60 @entity1 underwent resection of @entity475 at the National Heart Hospital. There was a male:female ratio of 40:20 and an age range of 4 to 56 years (mean 18 years). 22 @entity1 (36.7%) had a single or multiple additional @entity299 including left @entity3585 (12 cases), right @entity3585 (3 cases), @entity1757 (6 cases), @entity2461 (5 cases), @entity1498 (1 case), @entity4794 (1 case) and mitral @entity1146 associated with a single ventricle (1 case). Isolated resection of the organic sub-aortic with myotomy and wedge resection was performed in 47 @entity1 and Cooley technique in 2 @entity1 . Total aortic root replacement with a homograft valve was necessary in 4 @entity1 and the 22 @entity1 additional @entity299 received concomitant surgery. There was one early death (2.6%) amongst the 38 @entity1 with isolated organic sub-aortic @entity850 and no late deaths. There were 3 early deaths (13.7%) amongst the 22 @entity1 with additional @entity299 and one late @entity944 after 14 months. There were 7 non-fatal complications: a @entity583 , @entity713 and pacemaker insertion; three mild @entity337 ; one mild @entity339 ; an @entity943 due to @entity3153 ; and an aortic and mitral valve replacement after 9 years. 43 other @entity1 have been followed for 1 to 14 years and are symptom free. @entity714 is present in two of them. Resection of organic sub-aortic @entity850 with myotomy and wedge resection is a safe technique and offers an excellent prognosis for this group of congenitally compromised @entity1 .
