Abstract
The presence of systemic and pulmonary venous anomalies in late presenting transposition of great arteries (TGA) may make standard atrial switch procedures difficult, necessitating modification in the surgical procedure. We present a case report of a 13-year-old boy with a partial anomalous connection of right superior pulmonary vein with TGA and regressed left ventricle, where a combination of Warden procedure and Mustard procedure was used.
