A 68-year-old man with familial hypercholesterolemia developed effort angina and received a sirolimus-eluting stent (SES) to treat 99% stenosis in segment 6 of the left anterior descending coronary artery in January 2005. A further stent was implanted 14 months later to treat 99% restenosis at the proximal stent edge. A 66-year-old man with diabetes developed acute anterior myocardial infarction and underwent SES implantation to treat 90% stenosis in segment 4 atrioventricular node artery branch of the right coronary artery in April 2006. Heart failure developed 14 months later. Another stent was implanted to treat 100% obstructive stenosis of the proximal stent site. Late stent restenosis may occur over 1 year after SES implantation, so longer follow-up is required compared to bare metal stent.
