The Eustachian valve (EV) of the inferior vena cava and the Thebesian valve (TV) of the coronary sinus are incompletely regressed structures of embryonic sinus venosus . In the majority of cases, the EV and TV disappear completely after birth or are represented only by a thin crescentic fold. On echocardiography, these vestiges may mimic abnormal structures. We report a case with giant EV and TV which were initially misinterpreted as rims of an atrial septal defect (ASD) leading to the false diagnosis of ostium secundum ASD.
