A 60-year-old man, who had claudication in his right limb due to total occlusion of the right superficial femoral artery, received bare metal stents. Although the bare metal stents in the superficial femoral artery did not show restenosis 5 years after stent implantation, angiography revealed significant in-stent restenosis when he developed right critical limb ischemia at 8 years post implanta...
Drug-eluting stents (DES) have had a major impact in interventional cardiology. Compared to bare metal stents, they significantly reduce restenosis and the need for target vessel revascularization. Four DES are available in the US, the first-generation sirolimus-eluting (Cypher((R))) and paclitaxel-eluting (Taxus((R))) stents and later approved second-generation everolimus-eluting (Xience V((R)...
SEE PAGE 828 T he superficial femoral artery (SFA), the longest artery in the human body, is subjected to nearly constant torsion, bending, and compression. It is perhaps natural to expect it to be the Achilles heel of endovascular interventions, plagued by higher rates of in-stent restenosis (ISR) compared to other arterial beds. Indeed, the 12-month rates of ISR after implantation of modern b...
BACKGROUND Stent thrombosis (ST) is a rare but devastating complication of coronary stent implantation, occurring in 0.5% to 1.9% of patients with bare metal stents. The incidence of ST with drug-eluting stents is less well studied, particularly among patients outside of clinical trials. METHODS AND RESULTS The aim of this study was to evaluate the incidence and potential risk factors for ST ...
Patients with diabetes mellitus have worse outcomes after percutaneous coronary intervention than patients without diabetes mellitus. We compared the risk of stent thrombosis, myocardial infarction, death, and target lesion revascularization in diabetic and nondiabetic patients after implantation of drug-eluting stents or bare metal stents. In the Western Denmark Heart Registry, 12,347 consecut...
CONTEXT Restenosis within bare-metal stents is often treated with repeat percutaneous coronary intervention, although subsequent recurrence rates are high, with vascular brachytherapy (VBT) affording the best results. The effectiveness of drug-eluting stents in this setting has not been established. OBJECTIVE To investigate the safety and efficacy of the polymer-based, slow-release paclitaxel...
BACKGROUND Treatment of patients with drug-eluting stent (DES) in-stent restenosis (ISR) is more challenging than that of patients with bare-metal stent ISR. However, the results of everolimus-eluting stents (EES) in these distinct scenarios remain unsettled. METHODS AND RESULTS A pooled analysis of the RIBS IV (Restenosis Intra-Stent of Drug-Eluting Stents: Paclitaxel-Eluting Balloon vs Ever...
Coronary artery disease is a condition that affects millions of people worldwide and can lead to serious complications such as heart attack or stroke. The study's main objective compare drug-eluting stents versus bare-metal for treating coronary disease. present study aimed the efficacy safety (DES) bare metal (BMS) treatment (CAD). was conducted at two tertiary care hospitals, Hayatabad Medica...
OBJECTIVES To assess the effectiveness and cost-effectiveness of the use of coronary artery stents in patients with coronary heart disease (CHD). DATA SOURCES Electronic databases. REVIEW METHODS The review was conducted following accepted guidelines for conducting systematic reviews. Randomised controlled trials that include comparisons of percutaneous transluminal coronary angioplasty (PT...
IMPORTANCE In 2007, the American College of Cardiology/American Heart Association guidelines were revised for patients with cardiac stents in need of subsequent surgery to recommend delaying elective noncardiac surgery by 365 days in patients with drug-eluting stents (DESs). OBJECTIVE To examine the effect of the guidelines on postoperative major adverse cardiac events (MACEs) in subsequent n...
