the coarctation of the aorta (coa) is rare in adulthood. diagnosis is made by clinical suspicion and physical findings such as blood pressure difference between the upper and lower extremities, pulse delay in the femoral artery, and systolic murmur over the thoracic spine.the coa in adulthood and in patients with associated aneurysm is challenging and different complications even with proper tr...

conclusions this study confirms that primary pci revascularization is the best treatment for the acute st elevation mi with brilliant acute result and one- year high survival and acceptable cardiac and non-cardiac complications. studying the effects of using des and bms on long term cardiac mortality, morbidity and need to target vessels revascularization (tvr) shows that performing the pci in ...

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...

background: the biolimus-eluting stent (bes), with a biodegradable polymer, has not been previously compared with the everolimus-eluting stent (ees), as a second-generation drug-eluting stent (des).we sought to compare the 1-year outcome between the promus ™ stent (ees type) and the biomatrix ™ stent (bes type). methods: from march 2008 to september 2011, all patients treated with the promus™ s...

OBJECTIVE To compare the efficacy and safety of biodegradable polymer drug eluting stents with those of bare metal stents and durable polymer drug eluting stents. DESIGN Mixed treatment comparison meta-analysis of 258,544 patient years of follow-up from randomized trials. DATA SOURCES AND STUDY SELECTION PubMed, Embase, and Central were searched for randomized trials comparing any of the Fo...

background: small side branches, albeit less important than their larger counterparts, have not yet received due attention in the literature. nor has there ever been a comparison between drug-eluting stents and bare metal stents apropos side branch occlusion . the aim of this study was to compare the patency of small (≥0.5 and ≤1.5 mm in diameter) side branches with respect to bare metal vs. dr...

conclusions regarding the efficacy outcomes of the patients after des implantation, no differences were found between shorter (≤ 6 months) and longer (≥ 12 months) duration of dapt. what is worse is that longer duration (≥ 12 months) was associated with increased risk of bleeding complications. evidence acquisition this study was conducted at the department of cardiology, the first college of c...

INTRODUCTION AND OBJECTIVES Initial preclinical studies are required during the process of improving polymers, platforms, and drug-eluting systems for new coronary stent designs. Our objective was to analyze the efficacy and safety of new drug-eluting stent models compared with a conventional stent and commercialized drug-eluting stents in an experimental model with healthy porcine coronary art...

OBJECTIVES To evaluate the efficacy and safety of currently used drug eluting stents compared with each other and compared with bare metal stents in patients with diabetes. DESIGN Mixed treatment comparison meta-analysis. DATA SOURCES AND STUDY SELECTION PubMed, Embase, and CENTRAL were searched for randomised clinical trials, until April 2012, of four durable polymer drug eluting stents (s...
