Abstract:
A 2-year-old girl with cor triatriatum with unroofed coronary sinus and persistent left superior vena cava underwent preoperative radiofrequency catheter ablation for atrial tachycardia attack that developed after admission to our hospital. The procedure was not successful. Cryoablation was successfully performed during corrective surgery. Cutting back from the coronary sinus orifice, resection of the fibrous tissue above the mitral valvular orifice, closure of the excised fossa ovalis and coronary sinus orifice with a Gore-Tex patch, and ligation of the persistent left superior vena cava resulted in an excellent hemodynamic outcome. At 2-year follow-up, the patient was free from tachycardia attack.

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 middle...
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...
