ABSTRACT: Optimal surgical management for patients with transposition of the great arteries (TGA), ventricular septal defect (VSD) and left ventricular outflow obstruction (LVOTO) remains controversial. Although the Rastelli operation has been the most widely performed surgical procedure during the past decades, several studies have shown its suboptimal long-term prognosis. Other operations have been developed to improve results. This study was performed to compare the outcomes of the different surgical approaches for patients with TGA, VSD and LVOTO, as well as to determine risk factors for mortality and re-intervention. Records from 146 patients undergoing surgery from 1980 to 2008 from eight European hospitals were reviewed. Median age at operation was 21.5 months (range 0.2-165.1 months), and median weight was 10.0 kg (range 2.0-41.0 kg). Surgical procedures involved were the Rastelli procedure (82), arterial (24) and atrial (5) switch operation with relief of LVOTO, Réparation à l'Etage ventriculaire (REV) procedure (7) and the Metras modification (24), as well as the Nikaidoh procedure (4). The overall survival was 88%, 88% and 58% at 1, 10 and 20 years, respectively. The overall event-free survival was 80%, 45% and 26% at 1, 10 and 20 years, respectively. The REV procedure and the Metras modification were found to have the best long-term results in both survival and event-free survival rates. Multivariate analysis revealed year of operation, non-commitment of the VSD and prolonged cardiopulmonary bypass (CPB) time as risk factors for mortality while age at surgery, year of operation and type of corrective surgery were risk factors for re-intervention. Different surgical approaches have been developed for patients with TGA, VSD and LVOTO. The REV procedure and the Metras modification were observed to have favourable long-term results in survival and event-free survival rates. Aortic translocation techniques such as the Nikaidoh procedure seem promising, but further studies will be needed to confirm this in the long term.
