| Abstract: | OBJECTIVES: This study was undertaken to compare the outcomes of the Lecompte procedure and Rastelli repair in the transposition of the great arteries (TGA) with ventricular septal defect (VSD) and left ventricular outflow tract obstruction (LVOTO) and to determine the risk factors associated with unfavorable events. METHODS: Over a 12-year period (April 1990-October 2002), 35 patients underwent complete repair for TGA, VSD, and LVOTO. Twenty-five patients (71%) underwent the Lecompte modification, and mean age and weight were 23.4+/-18.2 months and 10.2+/-3.0 kg. Ten patients (29%) underwent the Rastelli operation, and mean age and weight were 39.1+/-36.1 months and 13.8+/-6.8 kg. RESULTS: One early death (3%) occurred after the Lecompte procedure and no late death. The mean follow-up was 5.9+/-3.8 years. Eight patients in the Rastelli group (80%) underwent a late reoperation for obstruction of the extracardiac conduit, and in four of these patients, a reoperation for LVOTO was concomitantly required. Reoperation was also required in six patients of the Lecompte group (25%); five for right ventricular outflow tract obstruction (RVOTO) including one for LVOTO and two for VSD leakage, and one for mitral regurgitation and left pulmonary artery stenosis. The interval prior to reoperation ranged from 1.6 to 11.1 years, with a mean of 5.7+/-3.1 years. The actuarial figures for freedom from reoperation at 5 and 10 years were 40.0+/-15.5 and 26.7+/-15.0% after the Rastelli operation and 95.7+/-4.3 and 63.5+/-12.6% after the Lecompte procedure (P = 0.02). Multivariate analysis by Cox regression analysis revealed that the risk factors of RVOTO were a younger age at operation, the Rastelli operation, and ductus ligation during the operation. CONCLUSIONS: The Lecompte procedure and Rastelli repair provide satisfactory early and late results. However, substantial late morbidity is more associated with conduit obstruction, and LVOTO in Rastelli repair rather than Lecompte procedure. |
