“…In addition, an increasing number of stent fractures follow-ing DES implantations have been reported recently. [5][6][7][8][9][10][11][12][13] SESs, a DES with a rigid and inflexible platform, are closely associated with stent fractures. This new phenomenon is not a negligible issue since it may play a major role in the mechanism of restenosis after SES implantation.…”

Late Multiple Stent Fractures Following Deployment of Sirolimus-Eluting Stents for Diffuse Right Coronary Artery Stenosis

SUMMARYWe 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. (Int Heart J 2007; 48: 767-772) Key words: Percutaneous coronary intervention, Drug-eluting stent, Stent strut fracture, Intravascular ultrasound, Multislice computed tomography DRUG-eluting stents (DESs) have been used to address in-stent restenosis, a problem that has been plaguing coronary stenting for the past decade. DES implantations have dramatically reduced the incidence of in-stent restenosis, and a number of studies have shown better clinical outcomes following DES implantation when compared with bare-metal stent (BMS) implantation.1-2) However, instent restenosis continues to occur after DES implantation in some cases, and its occurrence has been greatly responsible for limiting a patient's quality of life following percutaneous coronary intervention (PCI). Regarding sirolimus-eluting stents (SESs), previous trials have failed to show their advantage in preventing in-stent or peri-stent restenosis, particularly in patients with end-stage renal disease or insulin-dependent diabetes.3-4) Thus, the problem of in-stent restenosis remains unresolved. In addition, an increasing number of stent fractures followFrom the

“…Lee et al observed binary restenosis in six out of 10 patients (60%) with stent fracture and one patient had stent thrombosis. 5 Local mechanical irritation of the vessel can occur from fractured stent struts, which may result in inflammation and neointimal hyperplasia. Restenosis could also reflect decreased local drug availability secondary to distortion of the stent architecture and polymer coating.…”

“…Although drug-eluting stents has become the standard of care for percutaneous coronary intervention, the occurrence of late stent thrombosis has raised concern over their long-term safety. Stent fracture is being increasingly recognized as a potential cause of in-stent restenosis and stent thrombosis with the clinical manifestation of recurrent angina, myocardial infarction and even sudden death [3][4][5][6]. We report a rare case of delayed stent fracture after percutaneous coronary intervention with zotarolimuseluting stent (ZES).…”

International Journal of Case Reports and Images (IJCRI) is an international, peer reviewed, monthly, open access, online journal, publishing high-quality, articles in all areas of basic medical sciences and clinical specialties.Aim of IJCRI is to encourage the publication of new information by providing a platform for reporting of unique, unusual and rare cases which enhance understanding of disease process, its diagnosis, management and clinico-pathologic correlations. Case Report: A 64-year old male, a cigarette smoker, presented with rest angina. Coronary angiogram showed discrete 99% stenosis in proximal left anterior descending artery and a mid-eccentric 90% lesion in the right coronary artery (RCA). The patient was taken up for angioplasty of both the vessels. A type V fracture was detected after four years of zotarolimuseluting stent placement in the right coronary artery. Conclusion: Despite the recent advances in drug-eluting stents design, there remains a potential of stent fracture especially when a long drug-eluting stents is implanted in a tortuous vessel and is exposed to torsion forces at the hinge points.
