Can an operation provide superior outcomes for corrected transposition of the great arteries with left ventricular outflow tract obstruction? A multi-institutional study.

For patients with CCTGA/LVOTO, operative repair does not provide superior long-term outcomes, and anatomical repair results in a higher incidence of death. However, in patients with CCTGA/LVOTO with tricuspid regurgitation ≥ moderate, anatomical repair can reduce the risk of death in the long term.
