Positive Geometric Vascular Remodeling Is Seen After Catheter-Based Radiation Followed by Conventional Stent Implantation but Not After Radioactive Stent Implantation

Positive geometric vascular remodeling is seen after catheter-based radiation followed by conventional stent implantation but not after radioactive stent implantation.

BACKGROUND Recent reports demonstrate that intracoronary radiation affects not only neointimal formation but also vascular remodeling. Radioactive stents and catheter-based techniques deliver radiation in different ways, suggesting that different patterns of remodeling after each technique may be expected. METHODS AND RESULTS We analyzed remodeling in 18 patients after conventional stent impl...

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...

The pattern of restenosis and vascular remodelling after cold-end radioactive stent implantation.

BACKGROUND Edge restenosis is a major problem after radioactive stenting. The cold-end stent has a radioactive mid-segment (15.9 mm) and non-radioactive proximal and distal 5.7 mm segments. Conceptually this may negate the impact of negative vascular remodelling at the edge of the radiation. METHOD AND RESULTS ECG-gated intravascular ultrasound with three-dimensional reconstruction was perfor...
