Over a 22-year period, 81 @entity1 underwent initial operations for critical @entity472 at our institution. Their ages ranged from 3 days to 20 years (mean, 7.3 +/- 5.9 years). Fourteen (17%) were @entity1 less than 1 year old. Three @entity1 died perioperatively (3.7%). We have followed the survivors and 3 @entity1 who underwent initial operations elsewhere for a mean of 9.0 +/- 6.8 years (range, 2 to 23 years). To the present, 27 @entity1 have undergone one reoperation (24 of our initial survivors) at a mean interval of 7.3 years, with 2 perioperative @entity204 . Ten of these @entity1 have required a second reoperation at a mean interval of 3.7 years, with 2 @entity204 perioperatively. There were 3 late @entity204 after the initial procedure and 1 after a third operation. Actuarial reoperation-free survival is 56.7% at 10 years. While overall survival is 88.6% at 10 years, we find a significantly poorer survival among those @entity1 with @entity849 compared with those with @entity75 (p = 0.03). We believe that for @entity1 with all levels of @entity472 , good functional results and survival can best be obtained by follow-up, recatheterization, and reoperation.
