Abstract:
A case is reported of a 38-month-old female patient with an ostium secundum-type atrial septal defect, 25 mm in diameter, with intermittent hypoxemia and hypoplasia of the right ventricular cavity and tricuspid valve The right-to-left shunt through the atrial septal defect, responsible for these alterations, is explained by its proximity to the coronary sinus, and exacerbated by a persistent left superior vena cava. The cyanosis disappeared and normal hemodynamic status was achieved after closure of the atrial septal defect.

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...
