Rescue coronary artery bypass grafting during an arterial switch operation in a neonate restored left ventricular function, though signs of myocardial ischemia were found at 5-year follow-up.
Case Report (n=1)
Rescue CABG during neonatal ASO is effective for acute myocardial rescue but necessitates lifelong surveillance for late myocardial ischemia.
Necessitates lifelong ischemia surveillance after neonatal ASO rescue CABG; leaves open standardized protocols in larger cohorts.
We describe a case where prompt myocardial rescue revascularization at the time of arterial switch operation (ASO) for D-transposition of the great arteries (D-TGA) was fundamental for overcoming the acute intraoperative myocardial injury and for restoring prompt left ventricular function. Five years following the ASO the patient was asymptomatic but signs of myocardial ischemia were found at SPECT MI, potentially leading to ischemic complications. Adult patients who required coronary revascularization in the neonatal period need to be followed for life to prevent and treat any possible cause of further myocardial ischemia during childhood and adulthood.

Tessari et al. (2015) conducted a case report in D-transposition of the great arteries (D-TGA) (n=1). Rescue coronary artery bypass grafting was evaluated on Myocardial ischemia and left ventricular function. Rescue coronary artery bypass grafting during an arterial switch operation in a neonate restored left ventricular function, though signs of myocardial ischemia were found at 5-year follow-up.
