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