Transposition of the great arteries (TGA) is a common cardiac malformation in which the great arteries are discordant relative to the ventricles. The two common forms of transposition include D‐TGA, which presents with cyanosis early in life, and L‐TGA, which on the other hand, may permit survival to adulthood without being diagnosed in childhood. There are remarkable differences between these two forms of TGA in the clinical presentation, echocardiographic findings, and long‐term outcomes. Multimodality imaging in patients with TGA usually provides diagnostic and hemodynamic assessment for routine follow‐up and preoperative planning prior to surgical or transcatheter intervention. In this review, we present a summary of the fundamental echocardiographic aspects of these two forms of TGA with emphasis in the adult congenital heart disease population.
