BACKGROUND: Elevated white blood cell (WBC) count is associated with increased major adverse cardiovascular events (MACE) in the setting of acute coronary syndrome. The aim of this study was to evaluate whether similar associations persist in an all-comers population of patients undergoing percutaneous coronary intervention in the contemporary era. METHODS AND RESULTS: In the multicenter, prospective, observational PARIS study (Patterns of Non-Adherence to Anti-Platelet Regimens in Stented Patients Registry), 4222 patients who underwent percutaneous coronary intervention in the United States and Europe between July 1, 2009, and December 2, 2010, were evaluated...

BACKGROUND: Movement of the stent delivery system in the coronary bed as a result of the cardiac cycle is a well-known clinical observation that usually is either underestimated or ignored. This effect may potentially jeopardize precise stent deployment. We used a novel technology to objectively measure the relative intracoronary device motion in the different coronary segments throughout the cardiac cycle. METHODS: A total of 193 patients undergoing coronary angiography were enrolled and their studies were analyzed for device movement using the SyncVision System (Philips Volcano)...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom made scalloped/fenestrated stent-grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...

Treatment of coronary heart disease by percutaneous coronary intervention (PCT) is usually limited to the high restenosis rate after implantation of bare-metal stent. To solve the problem, the coating of PEGylated stereocomplex poly(l-lactide) (PEG-cPLA) was utilized on the surface modification of stainless steel (SS) sheet. Specifically, the 3-aminopropyltriethoxysilane (APTES)-modified methoxy-poly(ethylene glycol)-poly(d-lactide) (mPEG-PDLA) was grafted onto the surface of hydroxylated SS sheet through coupling reaction, and poly(l-lactide)-poly(ethylene glycol)-poly(l-lactide) (PLLA-PEG-PLLA) was coated onto the surface through stereocomplex interaction between DLA and LLA units...

The polymers poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and poly(n-butyl methacrylate) (PBMA) are employed in manufacturing the XIENCE family of coronary stents. PBMA serves as a primer and adheres to both the stent and the drug coating. PVDF-HFP is employed in the drug matrix layer to hold the drug everolimus on the stent and control its release. Chemical stability of the polymers of XIENCE stents in the in-vivo environment was evaluated by pyrolysis-gas chromatography with mass spectrometry (Py-GC/MS) detection...

In this work, rapamycin-eluting poly (d, l-lactic acid) coating (PDLLA/RAPA) was prepared on biodegradable Mg-Nd-Zn-Zr alloy (JDBM) for both in vitro and in vivo investigation of the degradation behaviors of the magnesium alloy stent platform. Electrochemical tests and hydrogen evolution test demonstrated significant in vitro protection of the polymeric coating against magnesium degradation both in short and long term. The 3-month in vivo study on the RAPA-eluting JDBM stent implanted into porcine coronary arteries confirmed its favorable safety, and in the meanwhile revealed similar neointima proliferation compared to the second generation DES Firebird 2 with no occurrence of adverse complications...

BACKGROUND: Patients receiving oral anticoagulation in addition to dual-antiplatelet therapy are known to be at high risk for bleeding events; thus, the selection of a drug-eluting stent (DES) versus a bare metal stent (BMS) can have important implications for patients with atrial fibrillation (AF) presenting with acute myocardial infarction (MI). METHODS AND RESULTS: From the National Cardiovascular Data Registry ACTION (Acute Coronary Treatment and Intervention Outcomes Network) Registry-Get With the Guidelines, we identified 14 427 AF patients presenting with acute MI undergoing percutaneous coronary intervention from 2008 to 2014...

Since the first balloon angioplasty by Andreas Grüntzig 40 years ago, interventional cardiology has witnessed the introduction of countless tools and techniques that have significantly contributed to broadening the application of percutaneous coronary interventions (PCI) in unprecedented anatomic settings. Heavily calcified, fibrotic coronary stenosis has traditionally represented a very challenging scenario for PCI, and a very common indication for surgical revascularisation. This was mostly due to the difficulty in adequately dilating these lesions and/or to the inability to deliver and implant stents appropriately, which is often associated with high rates of procedural complications and suboptimal long-term clinical outcomes...

VA Cooperative Studies Program #571 (DIVA) was designed to evaluate the efficacy of drug-eluting stents (DES) for reducing aortocoronary saphenous vein bypass graft (SVG) failure when compared with bare-metal stents (BMS) in participants undergoing stenting of de novo SVG lesions. Participants undergoing clinically indicated stenting of de novo SVG lesions were randomized in a 1:1 ratio to DES or BMS. Randomization was stratified by presence/absence of diabetes mellitus and the number of target SVG lesions (1 vs ≥2) within each participating site...

INTRODUCTION: Coronary arteries are exposed to several complex biomechanical forces during the cardiac cycle. These biomechanical forces potentially contribute to both native coronary artery disease, development of atherosclerosis and eventual stent failure. The aim of the present study was to characterize and define coronary artery axial rotation and the effect of stent implantation on this biomechanical factor. METHODS: Intravascular ultrasound (IVUS) images were obtained from porcine coronary arteries and analyzed in ultrasound analysis software used to evaluate myocardial strain and torsion in echocardiography...

OBJECTIVES: To estimate the incidence of stent thrombosis (ST) after early discontinuation of clopidogrel. BACKGROUND: Premature discontinuation of clopidogrel is the strongest risk factor for ST. In contrast, recent studies suggest that shorter dual antiplatelet therapy (DAPT) can be discontinued as soon as 3 months after stenting. However, these studies included very few ACS patients and were not powered for ST. Hence, little is known about the occurrence of ST in high-risk populations when DAPT is discontinued early...

OBJECTIVES: A calcified thrombus is rare, but needs to be recognized and to be differentiated from calcified nodule. METHODS: We report a case of acute coronary syndrome and a large intracoronary mobile mass, which was identified as a calcified thrombus by optical frequency domain imaging and intravascular ultrasound. RESULTS: Successful direct stenting indicated that mobile mass was a calcified thrombus, not a calcified nodule. CONCLUSIONS: Cardiologists should be aware that an intracoronary mobile mass could be a calcified thrombus...

Dual-antiplatelet therapy (DAPT) is considered mandatory after new-generation drug-eluting coronary stent implantation to reduce ischemic complications such as stent thrombosis, but the need for DAPT makes the timing of elective surgery difficult. Interrupting DAPT places patients at risk for stent thrombosis, and surgery in the setting of DAPT may lead to bleeding. The 2016 American College of Cardiology/American Heart Association guideline recommends delaying elective noncardiac surgery for a minimum 6-month period to reduce ischemic risks after the implantation of a second-generation metallic drug-eluting stent (DES)...

Min Soo Cho, Duk-Woo Park
The introduction of drug-eluting stents (DES) in the practice of percutaneous coronary intervention (PCI) has substantially reduced angiographic and clinical restenosis but is associated with an increasing propensity for very late stent thrombosis (ST). Among several clinical, lesion, or procedure-related predictors of ST, early discontinuation of dual antiplatelet therapy (DAPT) is the most important factor for DES-associated late thrombosis; therefore, the optimal duration of DAPT is a major issue to be critically considered in the current DES era...

Bioresorbable scaffold coated with antimitotic drug is the latest development in the coronary stents technology. The concept of temporary scaffolding and natural vessel healing after angioplasty is a very attractive alternative to conventional metal stents. The results of the first observational studies have confirmed their ultimate biodegradation. Newest results of randomised trials and registries in broader clinical and anatomical indications also revealed the limitations of the first generation of scaffolds...

Coronary artery disease is the leading cause of death among the men and women. One of the most suitable treatments for this problem is balloon angioplasty with stenting. Functionally graded material (FGM) stents have shown suitable mechanical behavior in simulations. While their deformation was superior to uniform materials, the study was aimed at finding the most suitable configuration to reach the optimum performance. A combination of finite element method (FEM) and optimization algorithm have been used to fulfil this objective...

BACKGROUND: The optimal dosing of novel oral P2Y12 receptor platelet inhibitors such as prasugrel or ticagrelor is unclear and especially challenging in East Asians. We hypothesize that half-dose prasugrel and ticagrelor may be sufficient for long-term maintenance management in Korean patients with the acute coronary syndrome (ACS) compared with conventional dosages.

Aspirin, the first antiplatelet agent, has been around since the 19th century, and is one of the most established drugs in history. With the improvement of coronary interventions in the past few decades, there has been more reliance on oral antiplatelet agents to reduce complications of in-stent restenosis/thrombosis. Clopidogrel was initially introduced in 1997, and within the past seven years, two additional oral antiplatelet agents have been approved by the U.S. Food and Drug Administration. With more potent antiplatelet agents comes increased risks of adverse effects...
