Left Ventricular Retraining and Double Switch in Patients With Congenitally Corrected Transposition of the Great Arteries

Congenitally corrected transposition of the great arteries (CC-TGA) is a complex form of congenital heart disease that may require left ventricular re-training prior to a double switch procedure. This study reviewed experience in 24 patients with CC-TGA who were enrolled in a left ventricular re-training program. Eighteen of the 24 patients underwent successful double switch, and 5 additional candidates are considered good candidates for a double switch. These results demonstrate that left ventricular re-training offers a reliable strategy in CC-TGA
