Delayed coronary stent fracture can present as stent thrombosis and progressive angina, which can be accurately diagnosed using IVUS and stent boost imaging and successfully treated with repeat stenting using more flexible stents.

Clinicians should consider very late fracture in delayed thrombosis after overlapping sirolimus-eluting stents; leaves open incidence and predictors.
A stent fracture is an emerging complication of the coronary stents. There are numerous risk factors for stent fractures; which include forceful exaggerated motion in the atrioventricular groove seen in right coronary artery, long stent, an ostial lesion at the point of maximum curvature in a tortuous vessel, stent over-expansion, stent overlapping with different size stents, complex lesion after stenting of a totally occluded vessel, Cypher stent and a highly mobile segment causing high mechanical stress. Furthermore, chronic stretch at specific vessel sites as bends may lead to late occurrence of fracture. Here we report a case of 40-year-old male who had two overlapping Cypher stents (3.0 × 13 mm and 2.75 × 18 mm) deployed at mid left anterior descending artery 2 years earlier presented with progressive chest pain.

Eldin et al. (2011) conducted a case report in Coronary stent fracture (n=1). Overlapping Cypher stents (Sirolimus-eluting stents) was evaluated on Stent fracture. A 40-year-old man developed a very delayed stent fracture and thrombosis two years after the deployment of overlapping sirolimus-eluting stents in the left anterior descending artery.
