Coronary angiography revealed critical in-stent restenosis in left circumflex artery (LCX; A, arrow) with anomalous artery from left anterior descending artery covering right coronary artery territory (A-C, arrow head). Percutaneous coronary intervention was done for LCX using a 2.75×19 mm bioabsorbable polymer drug-eluting stent (D, arrow). Cardiac computed tomography (E-H) demonstrated anomalous origin of right coronary artery from left anterior descending artery (arrow head).
