Echocardiography was used to diagnose partial anomalous pulmonary venous drainage into the coronary sinus of a 39-year-old man. An increased pulmonary vascular shadow was visible in the right lower field in the chest roentgenogram. Echocardiography showed an enlarged right atrium and ventricle, dilated coronary sinus, and an abnormal vessel draining into the coronary sinus. Color Doppler echocardiography showed drainage flow, and pulmonary angiography showed an abnormal vessel entering the coronary sinus in a right-sided angiogram. Connection of the right pulmonary veins to the coronary sinus was confirmed at surgery.
