(A) subcostal 2-chamber view: Abnormal color flow was observed at the junction of the superior vena cava and the right atrium, showing a continuous spectrum(arrow). RA, right atrium; LA, left atrium; SVC, superior vena cava. (B) subcostal 2-chamber view postoperative: Abnormal color flow was disappeared at the junction of the superior vena cava and the right atrium.

A routine echocardiography was performed, and a diagnosis of partial anomalous pulmonary venous connection was suspected (Figure 1A). At 6 months of follow-up, the patient remained well, and no residual shunt was found using the echocardiogram (Figure 1B).
(A) CTA: An abnormal blood vessel developed from descending aorta, and zigzagged to the right atrium. (B) Cardiac catheterization: An abnormal blood vessel developed from descending aorta, and zigzagged to the right atrium. (C) A VSD occluder has been placed at the inlet of tunnel, there was no obvious shunt revealed by aortography after closure. DAO, descending aorta; RA, right atrium; VSD occluder, ventricular septal defect occluder.

Subsequently, computerized tomography angiography (CTA) demonstrated an abnormal blood vessel from the descending aorta, ascending across the left main bronchus, and then descending to end in the right atrium (Figure 2A). The diameter of the tunnel inlet was 4 mm and that of the opening into the right atrium was only 1 mm (Figure 2B). No obvious shunt was revealed by aortography after device placement (Figure 2C).
