A Case of Complete Double Layer Stents Fracture in Right Coronary Artery

Abstract Background: Coronary stent fracture is a rare and serious complication, because it is closely related to restenosis, stent thrombosis, and subsequent target lesion revascularization. We describe the fracture of a double layer of stents in a patient with recurrent acute inferior myocardial infarction. Case presentation: A 67-year-old man was hospitalized for untypical chest pain, with prior stents implantation twice in proximal of right coronary artery due to acute and recurrent myocardial infarction, complete stent fracture was revealed in right coronary artery by angiography and optical coherence tomography. Conservative therapy was chosen, as enough lumen area was observed without aneurysm. No recurrent chest discomfort was reported in 3 month after discharge.Conclusion: Our case describes complete double layer of stents fracture in right coronary artery, the patient get better prognosis through conservative treatment.
