Abstract:
Cyanosis after surgical closure of ventricular and/or atrial septal defect is very unusual. We report a case of unroofed coronary sinus in a six-month-old boy who developed cyanosis after surgical closure of ventricular and atrial septal defects. Clinical presentation, diagnosis, and management are discussed.

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
