Is endovascular therapy the right choice for treatment of functional compression of anomalous right coronary artery arising from left coronary sinus with interarterial course?

We report a case of successful percutaneous coronary intervention (PCI) for reversible ischaemia owing to an anomalous right coronary artery arising from the left coronary sinus with malignant interarterial course and not associated with obstructive coronary artery disease (CAD). PCI for treatment of functional compression of the ostioproximal intramural segment of the anomalous vessel, though described in the literature, is technically challenging, requiring appropriate hardware selection; the peculiar anatomical milieu, in the absence of atherosclerotic CAD, lends itself to an uncertain long-term outcome following endovascular therapy with stenting.
