OBJECTIVES: We sought to establish whether there was a difference in outcome after aortic valve repair with autologous pericardial leaflet extension in pediatric and adult populations. METHODS: In our study, 128 patients (pediatric and adult) underwent valvular pericardial extension repair at our institution from 1997 through 2006. The patients were divided into either the pediatric group (< or =18 years of age; n = 54/128, 42%), with a mean age of 8.4 +/- 5.4 (range, 0-17 years), or the adult group (n = 74/128, 58%), with a mean age of 48.9 +/- 19.7 (range, 19-85 years). The endpoints of the study were mortality and reoperation rates. RESULTS: Thirty-day mortality for the adult group was 0, and for the pediatric group it was 1/54 (1.8%), with no statistical difference (P = .1) between the groups. Late mortality for the pediatric group was 2/54 (3.7%) and in the adult group was 2/74 (2.7%). There was no statistical difference (P = .12) between the groups. In the pediatric group, there were 6 total reoperations (6/54) in 5 patients, with one patient undergoing reoperation twice. From these 6 cases, 3 were re-repair and 3 had aortic valve replacement; the mean interval between original repair and reoperation was 4.3 +/- 2.5 years (range, 0.1-7.7 years). In the adult group, there were 5 total reoperations (5/74). From these 5 cases, 3 had aortic valve replacement and 2 re-repair; the mean interval between original repair and reoperation was 3.5 +/- 3 years (range, 0.1-7 years). There was no statistical difference in the reoperation rate between the 2 groups (P= .38). At late follow-up, 82% of all patients in the adult group had no aortic regurgitation or only a trace (grades 0 and 1) and 78% of all patients in the pediatric group had no aortic regurgitation or only a trace (grades 0 and 1). There was no statistical difference in either aortic regurgitation (P = .06) or aortic stenosis (P = .28) between the 2 groups. CONCLUSIONS: Aortic valve repair with autologous pericardial leaflet extension has low mortality and morbidity rates, as well as good mid-term durability in both the pediatric and the adult groups.
