Overview

Computed tomography can be helpful as a diagnostic tool in conditions where the echocardiographic findings are inconclusive.

CT

The radiologic appearance of TAPVC varies according to the site of abnormal venous drainage and whether the flow is obstructed.^[1]
The structure in which the anomalous vein terminates appears dilated; termination at the level of the coronary sinus, superior vena cava, or azygos vein leads to dilatation of that structure and produces characteristic abnormalities in the imaging appearance.
Computed tomography (CT) can be used as a diagnostic modality in congenital heart diseases.

Provides additional anatomic details compared to echocardiography
It is done faster compared to MRI, thus avoiding the need for anesthesia in small children.
