Anatomic correction of @entity1147 right ventricle with subpulmonary @entity1757 (the " XXXX ).

@entity1 @entity154 @entity1757 @entity1498 @entity1147 @entity337 @entity204
Seven @entity1 with @entity1147 right ventricle and subpulmonary @entity1757 (the @entity1147 ) underwent anatomical repair at the arterial level with transfer of the coronary arteries. At the time of operation, @entity1 ages ranged from 6 weeks to 33 months (mean 14.1 months) and weight ranged from 3.7 to 11.5 kg (mean 7.0 kg). Four @entity1 had prior pulmonary artery banding: Two of these four also had @entity1498 repairs, and one had a Blalock-Hanlon septectomy. Three different patterns of coronary artery distribution were encountered. Five @entity1 had side-to-side great arteries, and two had more or less anteroposterior great arterial relationships. There was one operative @entity204 (14.3%: 70% confidence limits 1.9 - 40.7%) resulting from muscular subvalvular right ventricular outflow tract obstruction (RVOTO). There have been no late deaths in the six survivors followed 6 to 31 months postoperatively (mean 14.8 months). One @entity1 required closure of a residual @entity1757 ( @entity1757 ) and infundibular resection for RVOTO 4 months postoperatively. All other survivors are functionally NYHA Class I. Five of the six survivors have undergone postoperative catheterization (mean interval 5.8 months). There was no @entity337 and good ventricular function in all @entity1 . In addition to the @entity1 with the residual @entity1757 , two other asymptomatic @entity1 had mild or moderate RVOTO. Compared with alternative surgical procedures for this @entity154 , anatomic correction has the advantages of acceptable operative mortality, use of the left ventricle as the systemic ventricle, no need for extracardiac conduits, and applicability to @entity1 with all variations of coronary artery and great artery anatomy.
