Abstract
BACKGROUND: Optimal management for coarctation of the aorta and ventricular septal defect remains controversial. The current study was undertaken to determine outcome, including recoarctation after 2-stage repair, at our institution. METHODS: Between 1984 and 1998, 79 patients younger than 3 months with coarctation and ventricular septal defect underwent 2-stage repair at our institution. The first-stage operation consisted of subclavian flap angioplasty and pulmonary banding. The median age at the time of first operation was 28 days (range, 4-90 days), and median weight was 3.2 kg (range, 1.2-5.1 kg). Hypoplastic aortic arch was present in 27 patients, and coexisting anomalies were present in 13 patients. After a mean interval of 10.4 +/- 9.6 months, they underwent a second-stage repair, with closure of the ventricular septal defect and pulmonary debanding. RESULTS: There were 2 hospital deaths and 4 late deaths. Mean follow-up was 9.2 +/- 4.9 years (range, 2.0-18.3 years), and actuarial survival was 92.3% at 10 years (95% confidence interval, 86.6%-98.3%). Age at first operation, body weight, hypoplastic arch, and coexisting anomalies had no significant influence on overall mortality. Freedom from recoarctation rate was 90.4% at 10 years (95% confidence interval, 83.7%-97.2%). CONCLUSION: To diminish mortality and the recoarctation rate and also to decrease the possibility of complications related to circulatory arrest and allogeneic blood transfusion, 2-stage repair is still an effective technique for coarctation of the aorta associated with ventricular septal defect.
