Chest radiograph (A,B). A huge "calabash" heart presented as appearance according to chest radiograph. The mediastinum is obviously in relation to heart border. TAPVR, total anomalous pulmonary venous return.

The cardiac enlargement resembles a "calabash" configuration (Figure 1).
A three-dimensional cardiac CT scan further delineated the supracardiac TAPVR in coronal view (A) and sagittal view (B). Pulmonary veins drained into a collecting vein. Later followed by left upper pulmonary vein to form an anomalous dilated vertical vein which eventually drains into left innominate vein and superior vena cava. TAPVR, total anomalous pulmonary venous return.

Three-dimensional images further delineated the supracardiac TAPVR in coronal view (Figure 2A) and sagittal view (Figure 2B).
Cardiac catheter angiogram (A,B) from femoral vein approach. It presented pulmonary veins drained into the collecting vein, and then join to form an anomalous vertical vein into left innominate vein and superior vena cava.

This vein ascended and formed a left innominate vein and finally drained into the SVC (Figure 3).
