    Abstract:
    During a 10-year period (1980 to 1990), 62 patients underwent complete repair for transposition of the great arteries, ventricular septal defect, and pulmonary outflow tract obstruction. Twenty-two patients (35%) (mean age 8.1 +/- 7.2 years) underwent the Rastelli operation: The ventricular septal defect was enlarged anteriorly in eight patients, and right ventricular-pulmonary artery continuity was established with an extracardiac valved (9/22) or nonvalved (13/22) conduit. Forty patients (65%) (mean age 3.3 +/- 3.2 years) underwent the Lecompte modifications: The conal septum was extensively excised when present (30/40), anterior translocation of the pulmonary bifurcation was performed in 32 patients, and right ventricular-pulmonary artery continuity was established by direct anastomosis without a prosthetic conduit. There were seven early deaths (11%; 70% confidence limits, 7% to 17%): two after the Rastelli procedure (9%; 70% confidence limits, 3% to 20%) and five after the Lecompte operation (12.5%; 70% confidence limits, 7% to 20%). Four patients were lost to follow-up, yielding a 93% complete follow-up (mean follow-up 55 months). There were two late deaths (one in each group). Actuarial probability of survival (+/- standard error) at 5 years was 83% +/- 9% after the Rastelli operation and 84% +/- 6% after the Lecompte procedure. All long-term survivors (except one in the Rastelli group) were in functional class I. Five patients in the Rastelli group underwent late reoperation for obstruction of the extracardiac conduit (28%; 70% confidence limits, 16% to 42%). Three late reoperations (10%; 70% confidence limits, 4% to 19%) were required after the Lecompte operation (one for residual ventricular septal defect and two for residual pulmonary outflow tract obstruction). At most recent examination, residual pulmonary outflow tract obstruction was present in seven patients of the Rastelli group (39%; 70% confidence limits, 26% to 53%) and in six patients of the Lecompte group (19%; 70% confidence limits, 12% to 29%). The combined likelihood of reoperation for pulmonary outflow tract obstruction and residual pulmonary outflow tract obstruction was significantly higher in the Rastelli group (67% versus 26%; p = 0.005). Both procedures provide satisfactory early and late results. The Lecompte operation allows complete repair in infancy, is feasible in patients with anatomic contraindications to the Rastelli operation, and may reduce the need for reoperation and the prevalence of residual pulmonary outflow tract obstruction.
