Arterial switch operation (ASO) is performed in infants for transposition of great vessels. It is associated with morbidity and mortality, with one of the causes being related to disruption of coronary vasculature, causing myocardial ischemia. When such coronary vessel compromise occurs, revascularization needs to be planned, however is a high-risk procedure in infancy. A thorough evaluation of myocardial viability becomes an essential requisite. Although myocardial perfusion and viability assessment is standard in adults, its feasibility in pediatric and especially infant populations must be established and standardized. We present the case of a 10-month-old child being evaluated for left ventricular infarction following an ASO.
