Rescue Coronary Artery Bypass Grafting in a Neonate After Arterial Switch Operation: A Temporary or a Lifetime Solution?

Abstract

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.
