A 59-year-old, non-diabetic, non-smoker male presented with rest angina in August 2006. Coronary angiography revealed the separate ostial origin of an anomalous left main (LM) arising from the right coronary sinus with a retroaortic course (Figure 1A). The proximal and distal left anterior descending (LAD) artery each had a type B lesion (Figures 1A and 1B), and were successfully stented using 3 x 23 mm and 2.5 x 23 mm sirolimus-eluting Cypher stents (Cordis), respectively (Figures 1C and 1D). A computed tomography scan confirmed separate ostial origin and retroaortic course of the LM (Figure 2). He remained asymptomatic during regular outpatient department follow-up visits for the next 12 years. In December 2018, he presented with exertional angina of 2-month duration. Coronary angiography revealed proximal in-segment in-stent restenosis (ISR) of the ostial and distal LAD stents (Figures 3A and 3B). Optical coherence tomography revealed significant LM shaft stenosis (Figure 3C´) along with ISR of both stents (Figures 3A´ and 3B´). Following cutting-balloon predilation of both ISR sites, a 3 x 38 mm Synergy everolimus-eluting stent (Boston Scientific) was deployed in the mid LAD (Figure 4A) and a 4 x 20 mm Synergy stent was deployed from LM-LAD (Figure 4B). The remaining LM shaft was covered with 2 overlapping 4 x 16 mm and 4 x 38 mm Synergy stents (Figure 4C). Proximal optimization of the LM was performed using a 5 x 12 mm non-compliant balloon. Ostial left circumflex was dilated with a 2.5 x 15 mm balloon only, without implantation of a stent (Figures 4B and 4C). Optical coherence tomography revealed well-apposed stents across the LM-LAD without any significant residual stenosis or edge dissection (Figures 4A´-4C´). He was asymptomatic at 2-month follow-up exam at the outpatient department.

This is a rare case of very late ISR of Cypher stents 12 years after PCI in a case of a single anomalous coronary.
