Clinical characteristics of stent fracture after sirolimus-eluting stent implantation

Predictors and Prognosis of Stent Fracture After Sirolimus-Eluting Stent Implantation

“…7,[9][10][11][12]14,15 The present study showed that hinge motion lesions and/or long stenting lesions with stent overlap are high risks for stent fracture, similar to the previous studies. Halkin et al reported that the mechanism of stent fracture might be related to mechanical factors such as strut stretching at the time of deployment followed by repetitive kinking of the stent during the cardiac cycle.…”

“…Although previous studies have reported that the incidence of stent fracture after SES implantation is 1.9-3.2%, [9][10][11][12] it was higher in the present study, which may be explained as follows. Firstly, the definition of stent fracture in the present study included both complete and partial types.…”

“…[9][10][11][12]15 Halkin et al reported stent fracture in RCA lesion without restenosis and suggested that stent fracture might occur long enough after PCI that the sirolimus effect was not compromised. 17 Min et al reported stent fracture in LAD lesion without restenosis and suggested that the degree of restenosis in fracture cases might be related with the timing of the fracture.…”

Research into biodegradable polymeric stents: a review of experimental and modelling work

“…The development of deadly ST is concertedly facilitated by hypersensitivity to the permanent presence of alloy and by incomplete repair of the endothelium at the site of vascular wall injury due to the anti-proliferative drug coatings [5] . Also, the presence of permanent stent could cause the increasing risk of strut fracture and failure under complicated loading and corrosive conditions, leading to heart attack or failure, unstable angina and other clinical complications in patients [6] .…”

Complications of Coronary Intervention

“….7% of cases. [1][2][3][4][5][6][7][8] However, because of limited sensitivity of angiography to detect fracture, its true incidence is still unknown. In a recent report analyzed from autopsy findings, stent fracture was observed in 29% of total patients.…”
