Results CSOA was preoperatively diagnosed in 2 of 6 patients by late phase coronary angiography findings, intraoperatively in 3, and postoperatively in 1. Coronary venous drainage was through the left superior vena cava (LSVC) to innominate vein in 3, through Thevesian veins to right atrium in 2, and both in 1. 3 patients needed surgical treatment without any mortalities.

متن کاملUnroofed coronary sinus defect.
Subsequent echocardiogram showed a dilated right ventricle with moderate tricuspid regurgitation. There was pulmonary hypertension (estimated pulmonary arterial systolic pressure, 55 mm Hg). Transthoracic Doppler studies showed a left-to-right shunt with a shunt ratio of 2:1. However, the ductus arteriosus was not patent and there were no septal defects. The coronary sinus was dilated and there...
