N2 - Purpose: Transposition of the great arteries with intact ventricular septum and left ventricular outflow tract obstruction (TGA + IVS + LVOTO) is a rare congenital cardiac malformation. This study aims to describe the operations performed for patients with TGA + IVS + LVOTO in the Society of Thoracic Surgeons Congenital Heart Surgery Database (STS-CHSD) and review their short-term outcomes. Methods: A total of 112 patients with the diagnosis of TGA + IVS + LVOTO in the STS-CHSD who underwent cardiac surgery between January 1999 and June 2021 were included. Patients’ characteristics, operative data, and postoperative outcomes were analyzed. Results: A total of 120 index cardiac operations were performed. The most common operations were the arterial switch procedure (n = 33), Glenn/HemiFontan (n = 10), Fontan (n = 9), Rastelli with ventricular septal defect (VSD) creation (n = 6), Damus-Kaye-Stansel procedure (n = 5), heart transplant (n = 5), and atrial switch (n = 4). Concomitant repair of subvalvar aortic stenosis was coded in 7 of 33 patients undergoing the arterial switch operation. The overall operative mortality was 4.5% (5 deaths in 112 patients undergoing 120 index cardiac operations). The overall major complication rate was 19% (23 of 120 cases). Major complications occurred in 9 of 33 (27%) of the arterial switch operations. The most common complications were unplanned reoperation in 14 of 120 cases (12%) arrhythmias requiring pacemaker implantation in 5 of 120 (4.2%), and postoperative mechanical circulatory support in 4 of 120 (3.3%). Conclusion: The diagnosis of TGA + IVS + LVOTO is rare in the STS-CHSD. The most common procedures performed for this disease were the arterial switch operation (often with concomitant repair of subvalvar aortic stenosis), Rastelli with VSD creation, and palliative functionally univentricular operations.
