Above the left atrial appendage, the trunk joined the left inferior pulmonary veins and formed a vertical vein (47 mm diameter) (Figure 1).
Maximum intensity projection (A) and 3D (B) reconstruction of the vessel arch formed by vertical vein, left brachiocephalic vein, and superior vena cava. RSPV - right superior pulmonary vein, RIPV - right inferior pulmonary vein, LIPV - left inferior pulmonary vein, VV - vertical vein, BCV - brachiocephalic vein, SVC - superior vena cava, Ao - aorta, PT - pulmonary trunk

All the findings were typical of supracardiac type of TAPVD (Figures 2A-B).
Axial scan, enlargement of right atrium (RA) and right ventricle (RV), ASD type II (arrow), heart apex dislocation to the left. LA - left atrium, LV - left ventricle

The heart apex was located posteriorly to the left mid axillary line (Figure 3).
Axial scan (A) dilatation of pulmonary trunk (PT), right pulmonary artery (RPA). SVC - superior vena cava, Ao - aorta, VV - vertical vein. Sagittal reconstruction (B) - enlargement of right ventricle (RV), pulmonary valve cusps thickening, dilatation of pulmonary trunk, right pulmonary vein confluence (*), LAA - left atrial appendage

Pulmonary trunk was dilated to 54 mm, right pulmonary artery achieved 38 mm, left pulmonary artery reached 33 mm (Figures 4A-B).

Peripheral pulmonary vessels were dilated and mosaic perfusion was noted, which is characteristic for pulmonary hypertension (Figures 5A-B).
