Key result
A patient with d-TGA presented with an unusual vertical intramural course of the left anterior descending coronary artery originating at the mid ascending aorta, increasing injury risk during ASO.
Case Report (n=1)
Highlights a rare anatomical variant of an intramural LAD with a vertical course in d-TGA, emphasizing the need for careful surgical planning during an arterial switch operation to avoid injury.
Intramural coronary arteries in patients with d-transposition of the great arteries (d-TGA) usually arise from the opposite sinus of Valsalva and traverse horizontally across the posterior/facing commissure before emerging externally from the appropriate sinus of Valsalva. Failure to make appropriate technical modifications during coronary transfer can result in an important risk of posttransfer ischemia. We report a case with an unusual course of an intramural left anterior descending (LAD) coronary artery in a patient with d-TGA, with origin at the mid ascending aorta and a vertical intramural course, increasing the susceptibility to injury during an arterial switch operation (ASO).

Sinha et al. (2017) conducted a case report in d-transposition of the great arteries (d-TGA) (n=1). Arterial switch operation was evaluated. A patient with d-TGA presented with an unusual vertical intramural course of the left anterior descending coronary artery originating at the mid ascending aorta, increasing injury risk during ASO.
