HIGH PRESSURE POST-DILATATION PROCEDURE MAY INDUCE NEOINTIMAL COVERAGE AFTER SILOLIMS-ELUTING STENT IMPLANTATION

Very Late Stent Thrombosis due to Neointimal Rupture After Paclitaxel-Eluting Stent Implantation

We report our experience of very late stent thrombosis (VLST) in a young male patient who underwent implantation of two paclitaxel-eluting stents (PES) six years ago. The patient was compliant with standard dual antiplatelet therapy, but he presented with acute myocardial infarction which was associated with VLST. Intravascular ultrasound showed neointimal rupture with thrombus within the PES i...

Stent thrombosis after drug eluting stent implantation.

ince stent thrombosis (ST) is one of the serious and mortal complications after percutaneous coronary intervention (PCI), especially drug-eluting stent (DES) implantation, we are eager that the means of predicting and preventing ST be established. Several studies have reported an association between inflammation and stent thrombogenicity. In a clinical setting, Hwang et al1 reported a positive ...

Stent Fracture after Everolimus-Eluting Stent Implantation

Compared with bare-metal stents, drug-eluting stents (DES) have greatly reduced the risk of in-stent restenosis (ISR) by inhibiting neointimal growth. Nevertheless, DES are still prone to device failure, which may lead to cardiac events. Recently, stent fracture (SF) has emerged as a potential mechanism of DES failure that is associated with ISR. Stent fracture is strongly related to stent type...

drug-eluting stent fracture within 6 days after stent implantation

Serial angioscopic evidence of incomplete neointimal coverage after sirolimus-eluting stent implantation: comparison with bare-metal stents.

BACKGROUND The time course of neointimal formation after stent implantation has not been studied extensively by angioscopy in the drug-eluting stent era. METHODS AND RESULTS Serial angioscopic findings at first follow-up (3.6+/-1.1 months), second follow-up (10.5+/-1.6 months), and third follow-up (21.2+/-2.2 months) after stent implantation were compared between sirolimus-eluting stents (SES...
