A CT scan reveals a dilated pulmonary artery and its branches, with the pulmonary trunk located on the right side in a parallel course with the ascending aorta.
The left ventricle is markedly dilated and shows a moderator band (morphologically, the right ventricle).
Multiple small VSD membranous and muscular types.
The rest of the major cardiac vessels are normally related anatomically to their corresponding chambers.
Overall features consistent with L-TGA
