Several cases of stent strut fractures (SSFs) have recently been reported following drug-eluting stent (DES) implantation Although SSF is a rare complication, it has been suggested to be a cause of restenosis. To date, a number of cases of stent fracture have been associated with sirolimus-eluting stents and they occurred from 2 days to about 2 years after the initial procedure. We report here on a case of paclitaxel-eluting stent fracture at the time of stent placement in a calcified coronary lesion.

The development of drug eluting-stents has been a breakthrough for the prevention of PCI postoperative restenosis, and the correlative researches have not yet stopped and are still the focus of the world. We review, in this article, the history of drug eluting-stents researches, analyze the research actualities and the problems existing, and forecast the developing trend in the future.

Coronary stent thrombosis (ST) has been regarded as a rare but catastrophic complication of bare-metal stent (BMS) implantation that normally occurs during the first few weeks after stenting. In the drug-eluting stent (DES) era, there has been increasing concern regarding higher rates of ST due to delayed endothelialization. However, a pooled meta-analysis of randomized clinical trials and registry studies showed rates of ST (0.4-1.5%) after DES to be similar to those of BMS. The rate of ST did not differ between sirolimus- and paclitaxel-eluting stents. Additionally, the rates of late ST were similar between DES and BMS. Remarkably, very late occurrence of ST, which develops up to 1-2 years after DES implantation, was significantly associated with complete cessation of antiplatelet therapy. Further large-scale studies are needed to determine the optimal combination and duration for antiplatelet therapy in order to prevent these serious thrombotic events.

We report a case of in-stent restenosis due to the fracture of a sirolimus-eluting stent, which was confirmed by intravascular ultrasound. It can be suggested that a stent fracture is an important cause of restenosis in this era of drug-eluting stents.

Stent thrombosis (ST) is a rare but catastrophic complication of a drug-eluting stent. Although dual antiplatelet therapy with aspirin and clopidogrel significantly reduces the occurrence of ST, it continues to occur and is occasionally associated with clopidogrel resistance. Here, we describe a 71-yr-old man with subacute stent thrombosis and clopidogrel resistance following drug-eluting stent implantation who underwent successful ticagrelor rescue therapy.
