POCUS revealed dilatation of the coronary sinus to a diameter of 16 mm (Figure 1 and online Video S1).
Transesophageal echocardiography showed an atrial septal defect of the superior sinus venosus type with Left to Right flow. RA, right atrium; LA left atrium; S atrium septum with septum defect

Transesophageal echocardiography showed an atrial septal defect of the superior sinus venosus type with left-to-right flow (Figure 2).
Cardiac computerized tomography with emphasis on pulmonary veins was performed. The right atrium (RA) and right ventricle are significantly dilated. There is an anomalous shunt defect at the superior portion of the interatrial Septum. The right superior pulmonary vein (RSPV) is seen having confluence with the right superior vena cava (RSVC) at the level of entrance of RSPV into the mediastinum.
