Transposition of the great arteries (D-TGA) is a conotruncal abnormality characterized by discordant ventricular-arterial connections. In D-TGA, the aorta arises from the right ventricle and the pulmonary artery arises from the left ventricle. The aorta is anterior and rightward. The pulmonary and aortic circulations are in parallel instead of in series.
D-TGA occurs in ~31.5 in 100,000 live births
D-TGA is the second most common cyanotic heart disease following tetralogy of Fallot
