“…A newer imaging method for detecting SF, optical coherence tomography may be useful for SF diagnosis. 35 Third, we could not distinguish late ST from thrombosis because of ISR completely. We performed IVUS after thrombus aspiration and predilation using small balloon in all SF cases with ST. IVUS revealed that there were thrombi at the culprit site and less neointimal hyperplasia within the stent, except for the culprit site.…”

Background-Stent fracture (SF) after drug-eluting stent implantation has recently become an important concern because of its potential association with in-stent restenosis and stent thrombosis. However, the incidence and clinical impact of SF after everolimus-eluting stent implantation remain unclear. Methods and Results-A total of 1035 patients with 1339 lesions undergoing everolimus-eluting stent implantation and follow-up angiography 6 to 9 months after index procedure were analyzed. SF was defined as complete or partial separation of the stent, as assessed by plain fluoroscopy or intravascular ultrasound during follow-up. We assessed the rates of SF and major adverse cardiac events, defined as cardiac death, myocardial infarction, stent thrombosis, and clinically driven target lesion revascularization within 9 months. SF was observed in 39 of 1339 lesions (2.9%) and in 39 of 1035 patients (3.8%). Ostial stent location and lesions with hinge motion, tortuosity, or calcification were independent predictors of SF. The rate of myocardial infarction and target lesion revascularization were significantly higher in the SF group than in the non-SF group (5.1% versus 0.4%; P=0.018 and 25.6% versus 2.0%; P<0.001, respectively). Stent thrombosis was more frequently observed in the SF group than in the non-SF group (5.1% versus 0.4%; P=0.018). Major adverse cardiac events within 9 months were significantly higher in the SF group than in the non-SF group (25.6% versus 2.3%; P<0.001). Conclusions-SF after everolimus-eluting stent implantation occurs in 2.9% of lesions and is associated with higher rate of major adverse cardiac events, driven by higher target lesion revascularization and stent thrombosis.

“…It may be that less severe SF types without major alterations of the stent architecture are more difficult to identify with this technique. Similarly, OCT has also been used to detect SF, and it is considered that due to its high resolution gives unique insights into the in-vivo appearance of this complication [27,28]. However, we were able to identify the region of fracture with certainty in only 42.8% of cases, all of the most severe form (1 Type-4 and 2 Type-3), and with significant restenosis.…”

“…In the DES case, with suppression of initial hyperplasia, OCT offers supreme visualization of the stent struts. However there are only scarce reports in the literature assessing SF with OCT. Barlis et al, reported two cases of SF assessed with OCT, supporting the use of this imaging technique for SF detection [5]. It is not clear whether the incidental detection of International Journal of Cardiology 149 (2011) e72-e74 SF in an angina free patient should be followed by coronary angiography and what kind of treatment should be applied.…”
