A 24-day-old apparently asymptomatic neonate was found to have complete transposition of great arteries with small patent ductus arteriosus and restrictive patent foramen ovale. The neonate was found to have relatively high saturations (saturations = 88%) despite inadequate mixing communications. Echo findings were suggestive of significant dilatation of right atrium and right ventricle and left ventricular (LV) mass regression. Further echo interrogation revealed coexisting total anomalous pulmonary venous connection (TAPVC) as the cause of relatively high saturations and early LV mass regression. The patient was planned for follow-up and underwent successful Senning repair at the age of 8 months. Hemodynamics and echo findings of this association of TGA with TAPVC have been described in this case report.
