Key result
In a neonate with d-TGA and a novel coronary artery pattern, a coronary unroofing procedure and arterioplasty successfully resolved postoperative myocardial ischemia and restored normal ventricular function.
Why the study?
Coronary artery pattern is a major determinant of postoperative outcome in d-TGA, and anomalous patterns can cause myocardial ischemia or sudden death.

Advanced cardiac imaging and a multidisciplinary approach, including coronary unroofing, are essential for managing novel and complex coronary artery patterns in neonates with d-TGA undergoing arterial switch operations.
Transposition of great arteries (d-TGA) is often associated with various coronary artery (CA) patterns. These anomalous patterns can cause variable clinical symptoms of coronary ischemia including sudden death. CA pattern is one of the major determinants of outcome in TGA postoperatively. An advanced cardiac imaging and a multidisciplinary care approach are essential for a favorable outcome. Here, we describe a novel CA origin pattern in a neonate with d-TGA, who developed myocardial ischemia and required a coronary unroofing procedure for a full recovery.

Chegondi et al. (2022) conducted a case report in Transposition of great arteries (d-TGA) (n=1). Arterial switch operation and coronary unroofing procedure was evaluated on Clinical recovery and coronary artery patency. In a neonate with d-TGA and a novel coronary artery pattern, a coronary unroofing procedure and arterioplasty successfully resolved postoperative myocardial ischemia and restored normal ventricular function.
