Two- and three-dimensional echocardiographic unroofed coronary sinus

We present the 2-dimensional findings and 3-dimensional reconstruction of i mages from an 18-year-old patient with unroofed coronary sinus, persistent left superior vena cava, a common atrium with levoisomerism, ventricular se ptal defect, and double-outlet right ventricle. The left superior vena cava showed continuity with the floor of the coronary sinus. Diagnosis of the c onstellation of anomalies established by transesophageal reconstruction cla rified the continuity of the coronary sinus with left superior vena cava an d atrial wall.
