Dextro-Transposition of the Great Arteries: Long-term Sequelae of Atrial and Arterial Switch.

Over the last 50 years, improved surgical techniques and progressive medical management have allowed patients with complete or dextro-transposition of the great arteries (D-TGA) to survive into adulthood. Older adult patients underwent an atrial switch procedure (Mustard or Senning operation), whereas the younger cohort of patients with TGA has undergone the arterial switch operation (ASO). The Mustard/Senning maintains the right ventricle as the systemic ventricle, whereas the more recently adopted ASO attempts to restore normal physiologic and anatomic relationships. Neither operation is without consequence. Neither is without consequence and require long term follow up.
