(A) Initial transthoracic echocardiography. Regurgitation through the tricuspid valve was noted. (B) Echocardiography after septal defect closure. Tricuspid regurgitation was improved.

(A) Transesophageal echocardiography. A 1.74 cm-sized interatrial septal defect (arrow) located near the inferior vena cava (IVC) was noted. (B) Coronary computed tomography (CT) angiography. CT revealed an atrial septal defect (arrow) near the IVC, with a size of approximately 1.7 cm, and a small ridge on the posterior side of the defect. LA, left atrium; RA, right atrium.

The results showed an inter-ASD near the IVC with a size of approximately 1.74 cm (Fig. 2A). Chest computed tomography revealed an approximately 1.7 cm-sized inferior venosus ASD (Fig. 2B).
(A) Follow-up echocardiography the day after the procedure. (B) Follow-up echocardiography 1 year after the procedure. The Amplatzer (St. Jude Medical) closure device (arrows) was well placed. LA, left atrium; RA, right atrium.

On follow-up echocardiography, there was no abnormal shunt flow, the occlusion device was well placed (Fig. 3A), and the tricuspid regurgitation (Fig. 1B) and pulmonary hypertension were improved (the right ventricular systolic pressure was 41 mmHg, moderate tricuspid regurgitation was noted, and the TAPSE was 1.92 cm). Follow-up echocardiography 9 months after the procedure showed that the occluder device was well placed, without abnormal shunt flow (Fig. 3B).
