ABSTRACT = {Asymptomatic coronary artery obstruction represents a significant diagnostic challenge in patients with Dextro-Transposition of the Great Arteries and
history of Arterial Switch Operation. We report the case of a 17-year-old boy with
anomalous origin of left circumflex artery from the right coronary artery, who
underwent neonatal arterial switch operation and developed silent myocardial
ischemia under stress on myocardial scintigraphy. Despite coronary angiogram
and intravascular ultrasound showed only intermediate stenosis of the right coronary artery ostium, the physiological analysis, through the employment of pressure
wire, demonstrated a severe reduction of coronary fractional flow reserve after
pharmacologically induced hyperemia. Thus, the patient was treated with implantation of drug eluting stent. Invasive fractional flow reserve of coronary stenosis
may represent a useful tool to guide revascularization strategy in this population.},
