Twenty-two patients underwent 23 late reoperations after total correction of tetralogy of Fallot from 1965 to 1990. Indications for reoperation included: isolated ventricular septal defect (VSD) in 9 patients (41%), isolated right ventricular outflow tract (RVOT) obstruction in 3 patients (13.7%), VSD associated with a RVOT obstruction in 7 patients (31.8%), aneurysm of the pericardial RVOT patch in 1 patient (4.5%), aortic insufficiency with a residual VSD in 1 patient (4.5%), and tricuspid regurgitation in 1 patient (4.5%). The reoperation consisted of closure of a residual VSD in 17 patients, relief of a RVOT gradient in 11, insertion of a RVOT valve in 4, tricuspid valve replacement in 1 (reoperated twice), aortic valve replacement in 1, and excision of a RVOT aneurysm in 1. Two patients died in hospital (9%) but there were no early deaths in the 11 patients reoperated upon after 1978. Mean follow-up period was 135 months. There were 2 late deaths. The actuarial 20-year survival was 87%. Of the surviving patients, 16 (89%) were in New York Heart Association class I, 1 (5.5%) was in class II, and one (5.5%) was in class III. One patient required a second reoperation for tricuspid bioprosthesis degeneration and 1 patient had moderate recurrent RVOT gradient due to calcified pulmonary bioprosthesis. This study tends to support the policy of recommending reoperation in the presence of surgically significant residual defects. Reoperation is associated with a low early mortality and good long-term results.
