(A) The subxiphoid biatrial view showed the common pulmonary venous lumen draining into the coronary sinus. (B) The suprasternal fossa section showed a vertical vein flowing into the innominate vein. (C) The spectrum of tricuspid regurgitation. (D) The CT image showed common venous trunk opening into the coronary sinus. CPV, common pulmonary venous lumen; RA, right atrium; ASD, atrial septal defect; VV, vertical vein; INV, innominate vein; CS, coronary sinus; RVC, right superior vena cava.

Echocardiography showed that the right pulmonary vein and the left inferior pulmonary vein formed a venous trunk that drained into the right atrium through the coronary sinus, and the left superior pulmonary vein was combined with the innominate vein through the vertical vein and into the right atrium (Figures 1A, B). The size of the ASD was approximately 36 x 46 mm (Figure 1C). ASD with TAPVC (mixed type) and pulmonary hypertension was performed by echocardiography and CT (Figure 1D). ASD repair and TAPVC repair were carried out in June 2020, and the patient recovered well from surgery.

A patent foramen ovale and an ASD (7 mm) with TAPVC (mixed type) were detected (Figure 2C). The diameter of the coronary sinus was about 6 mm (Figures 2A, B), and the blood flow was accelerated by about 2.17 cm/s at the entry point into the right atrium (Figure 2D).
