Echocardiographic diagnosis and surgical closure of coronary sinus type of atrial septal defect.

Coronary sinus type of atrial septal defect (ASD CS) is a rare cardiac anomaly and is rarely diagnosed by only transthoracic echocardiography prior to surgical operation. We now describe a technique to treat this defect with the aid of two-dimensional echocardiography, which prevents trauma to the conduction system and maintains drainage from the coronary sinus into the right atrium (RA).
