the invention of the drug-eluting stent (des) has brought about revolutionary changes in the field of interventional cardiology. in the des era, in-stent restenosis has declined but new issues such as stent thrombosis have emerged. one of the emerging paradigms in the des era is stent fracture. there are reports about stent fracture leading to in-stent restenosis or stent thrombosis. most of th...

Percutaneous coronary intervention with stenting is considered recently as the most common procedure for the treatment of symptomatic coronary. The article reviewed 41 studies published during 1997-2019 on intracoronary brachytherapy for in-stent restenosis of a drug-eluting stent. Intracoronary radiation therapy was finally confirmed in the setting of in-stent restenosis using as adjunctive th...

Cardiovascular events are the most common cause of morbidity and mortality worldwide. Coronary artery diseases, including myocardial infarctions, prevalent among all populations. There multiple management strategies for coronary but stent implantation is effective interventions. Nevertheless, some patients develop restenosis intervened vessel, number constitutes about 10%-20% patients. In-stent...

Abstract Left subclavian artery occlusion is frequently treated by stent placement. The most commented on In-Stent Restenosis excessive thrombus that squeezes the and leads to vessel occlusion. In this paper, an automatic system provided segment left arteries aortic arches from chest MRI (Magnetic Resonance Imaging) images, then identify of based gray-levels extracted arch. Experimental results...

OBJECTIVES The purpose of this prospective study was to evaluate the immediate results and the 6-month angiographic recurrent restenosis rate after balloon angioplasty for in-stent restenosis. BACKGROUND Despite excellent immediate and mid-term results, 20% to 30% of patients with coronary stent implantation will present an angiographic restenosis and may require additional treatment. The opt...

BACKGROUND Intravascular ultrasound (IVUS)-guided stent implantation and the availability of a reference chart to predict the expected in-stent restenosis rate based on operator-dependent IVUS parameters may interactively facilitate optimal stent placement. The use of IVUS guidance protects against undue risks of dissection or rupture. METHODS AND RESULTS IVUS-determined post-stent-implantati...

AIMS In many countries, drug-eluting stent implantation is the dominant interventional strategy. We evaluated the clinical, angiographic, procedural, and intravascular ultrasound (IVUS) predictors of angiographic restenosis after sirolimus-eluting stent (SES) implantation. METHODS AND RESULTS SES implantation was successfully performed in 550 patients with 670 native coronary lesions. Six-mon...

OBJECTIVES This study was performed to investigate the causes of diffuse and aggressive intra-stent restenosis. BACKGROUND Although restenosis is usually considered to be a dichotomous variable, there is clinical relevance to the severity of restenosis. It is not known which variables are predictive of diffuse or aggressive intra-stent restenosis. METHODS A consecutive series of 456 coronar...
