We describe a case of congenitally corrected transposition of the great arteries plus dextrocardia and normal anatomical abdominal viscera. Systemic (tricuspid) valve replacement was performed due to moderately severe valve regurgitation. An unusual operative technique was used because of the patient's rare morphology. On cardiopulmonary bypass, the systemic valve was approached via a left atriotomy anterior to the left pulmonary veins, whereby the surgeon was positioned on the patient's left side. As the surgeon had excellent exposure from the opposite side of the table, he was able to perform a tricuspid valve replacement through the left atrium. Our aim is to share our limited experience of such cardiac morphology, which may oblige the surgeon to be positioned on the left side of the table to perform systemic valve surgery.
