Coronary Stent Fracture Causing Myocardial Infarction: Case Report and Review of Literature

Coronary stent fracture (SF) is a potential cause of failure increasing the risk for in-stent restenosis, thrombosis, target lesion revascularization and major adverse cardiac events. Overall incidence SF ranges from <1.0% up to 18.6% can be found in 60% failed devices. Advanced imaging techniques have improved detection SF. However, defining optimal therapeutic approach towards these complex lesions challenging. This review summarizes most important publications on topic discusses current insights into pathophysiology, diagnostic tools, classification management. Furthermore, two illustrative cases leading myocardial infarction are presented, which demonstrate typical factors such as vessel angulation hinge motion, stenting right coronary artery, use long stents multiple layers.
