Bifurcation lesions are present in one out of every five percutaneous coronary interventions. Despite the progress techniques, materials, and imaging technologies, bifurcation approach remains challenging, its treatment results higher rates adverse cardiac events when compared to with no involvement. The best technique treat is still a subject debate. For most cases, provisional preferred, sinc...
PURPOSE The paper presents the process of numerical modeling and simulation of balloon angioplasty of the coronary artery using Finite Element Method. METHODS The authors focused on the issue of applying adequate pressure in an arterial tissue during the post-dilatation process in the "kissing balloon" stenting technique applied to patients with bifurcation stenosis. Despite great progress in...
BACKGROUND Long lesions have been associated with adverse outcomes in percutaneous coronary interventions with bare metal stents (BMS). However, the exact impact of lesion length on the short- and long-term outcomes of drug-eluting stent (DES) implantations is not as clear. METHODS AND RESULTS This study compared the impact of lesion length on angiographic and clinical outcomes of BMS and DES...
to study the resistance to standard dosage of clopidogrel among iranian patients following percutaneous coronary intervention measured by platelet aggregation test.patients undergoing percutaneous coronary intervention in imam hussein medical center, tehran, iran, who were under treatment with aspirin, but had no history of clopidogrel usage, entered the study. patients received standard dosage...
BACKGROUND Classical crush has a lower rate of final kissing balloon inflation (FKBI) immediately after percutaneous coronary intervention (PCI). The double kissing (DK) crush technique has the potential to increase the FKBI rate, and no prospective studies on the comparison of classical with DK crush techniques have been reported. MATERIALS AND METHODS Three hundred and eleven patients with ...
OBJECTIVES The purpose of this study was to investigate the safety and efficacy of new-generation drug-eluting stents (DES) versus early-generation DES in women undergoing complex percutaneous coronary intervention (CPCI). BACKGROUND Whether the benefits of new-generation DES are preserved in women undergoing complex percutaneous revascularization is unknown. METHODS We pooled patient-level...
Objectives To clarify the underlying mechanism for the high restenosis rate after the coronary angioplasty for the chronic total occlusion by using the coronary angioscope. Background Coronary angioplasty for the chronic total occlusion is associated with higher restenosis rate than for highly stenotic lesion. However, the difference in the restenosis rate has not been discussed from the angios...
BACKGROUND The present study aimed to evaluate the clinical performance, in the daily practice of a busy catheterization laboratory, of a novel drug-eluting stent (DES) built with an ultra-thin-strut metallic platform, eluting sirolimus at low doses, abluminal coated with biodegradable polymers, and mounted in a low-compliant delivery system. METHODS Prospective, single-arm study, comprising ...
BACKGROUND Central anthropometric indexes are better than the body mass index to discriminate elevated coronary risk. However, the Body Mass Index (BMI) is still the most frequently studied anthropometric index on outcomes of patients undergoing percutaneous coronary angioplasty (PCI). OBJECTIVE To recognize, among several anthropometric indexes of obesity, which one best discriminates MACE (...
