Lecompte procedure for correction of the transposition of the great arteries associated with ventricular septal defect and left ventricle outflow tract obstruction.

摘要

OBJECTIVE: To evaluate the Lecompte procedure used for the correction of transposition of the great arteries (TGA) associated with ventricular septal defect (VSD) and left ventricle outflow tract obstruction (LVOTO) and to present the intermediate and long-term results of the surgery. METHODS: Between February 1994 and July 2005, seven patients with ages between 2 and 8 years (median: 3.0) suffering from TGA, VSD and LVOTO underwent corrective surgery. In six cases, the Lecompte procedure was performed. This technique consists in right ventriculotomy, extensive resection of the conal septum and construction of a ventricular tunnel connecting the left ventricle to the aorta (LV-Ao). The remaining case presented with obstruction of a valvular prosthesis implanted between the right ventricle and the pulmonary artery (RV-PA) and RV failure. This case was converted to the Lecompte procedure. RESULTS: The cardiopulmonary bypass time varied from 105 to 194 minutes (Median: 130) and the aortic clamping time varied from 65 to 90 minutes (Median: 78). There was one death in the immediate post-operative period due to coagulopathy followed by RV failure. Six patients were released from hospital between the 5th to 30th postoperative days (Median: 11) and the follow up period was from 12 to 144 months (Median: 73.6). CONCLUSIONS: The Lecompte procedure presents the following advantages: 1. Surgical indication for infants, 2. Low morbidity and mortality rates, 3. Free from reoperation over the long term. 4. Possibility of conversion of the Rastelli procedure into the Lecompte procedure.
