Echocardiography and Doppler examination acts as the main diagnostic tool in transposition of great artyeries. It shows the pulmonary arteries arising from the posterior left ventricle, and the aorta rising anteriorly from the right ventricle. It also detects other associated anomalies like ventricular septal defect (VSD), patent ductus arteriosus and the coronary artery anatomy

Echocardiography of a complex transposition with a ventricular septal defect and pulmonary stenosis.

Echocardiogram in transposition of the great arteries. This subcostal view shows the left ventricle giving rise to a vessel that bifurcates, which is thus identified as the pulmonary artery.
Abbreviations: RA=right atrium, RV=right ventricle, LV=left ventricle, PT=pulmonary trunk, LPA and RPA=left and right pulmonary artery.
