Key result
Complete single-stage repair successfully corrects coexisting TGA and infracardiac TAPVC without ECMO support.
Why the study?
Coexisting d-TGA and infracardiac obstructed TAPVC is a rare combination with limited cases described, and optimal surgical management strategies are not well established.
Case Report (n=1)
Complete anatomical correction of coexisting d-TGA and obstructed infracardiac TAPVC can be successfully performed without ECMO support, even in late presenters, as the obstructive physiology may help preserve left ventricular mass.
Coexisting transposition of the great arteries (d-TGA) and total anomalous pulmonary venous connection (TAPVC) is a rare combination, with the infracardiac variety being more rare. So far, only a few cases are described in the literature with combined infracardiac TAPVC and d-TGA. We present a 4-month-old girl having TGA and obstructed infracardiac TAPVC with early left ventricle mass regression. She underwent successful complete surgical anatomical correction of this rare entity without postoperative mechanical circulatory support uneventfully. Simultaneous complete anatomical correction of TAPVC and d-TGA with arterial switch operation and common chamber to left atrium anastomosis can be done with excellent outcome even in late presentation with features of obstruction.

Satsangi et al. (2026) conducted a case report in Coexisting transposition of the great arteries and obstructed infracardiac total anomalous pulmonary venous connection (n=1). Arterial switch operation with infracardiac TAPVC repair was evaluated on Surgical survival and postoperative recovery. Complete surgical anatomical correction of coexisting transposition of the great arteries and infracardiac total anomalous pulmonary venous connection was successfully performed without requiring ECMO support.
