We report a case of late multiple stent fractures following the deployment of sirolimus-eluting stents (SESs) for diffuse right coronary artery (RCA) stenosis. A 44-year-old male with hyperlipidemia was referred to our hospital for acute myocardial infarction (AMI). Percutaneous coronary intervention (PCI) was performed for total occlusion of the proximal segment of the RCA, and 5 SESs were consecutively implanted for long, diffuse stenotic lesions. A follow-up coronary angiography (CAG) performed 8 months later revealed strut fractures in the middle of all the stents, except the most proximal one. Multislice computed tomography confirmed the locations of the fractured struts inside of the stents.
