OBJECTIVES: We evaluated the angiographic and clinical outcomes in patients with severely calcified lesions and systolic dysfunction who underwent orbital atherectomy (OA). We hypothesized that OA would provide similar outcomes in patients with systolic dysfunction compared with patients with preserved systolic function. BACKGROUND: Systolic dysfunction is associated with an increased risk of adverse clinical events after percutaneous coronary intervention (PCI)...

Background -Stent thrombosis (ST) is a serious complication following coronary stenting. Intravascular optical coherence tomography (OCT) may provide insights into mechanistic processes leading to ST. We performed a prospective, multicenter study to evaluate OCT findings in patients with ST. Methods -Consecutive patients presenting with ST were prospectively enrolled in a registry using a centralized telephone registration system. After angiographic confirmation of ST, OCT imaging of the culprit vessel was performed with frequency domain OCT...

BACKGROUND: Adherence to antiplatelet medications is critical to prevent life threatening complications (ie, stent thrombosis) after percutaneous coronary interventions (PCIs), yet rates of nonadherence range from 21-57% by 12 months. Mobile interventions delivered via text messaging or mobile apps represent a practical and inexpensive strategy to promote behavior change and enhance medication adherence. OBJECTIVE: The Mobile4Meds study seeks to determine whether text messaging or a mobile app, compared with an educational website control provided to all Veterans, can improve adherence to antiplatelet therapy among patients following acute coronary syndrome (ACS) or PCI...

INTRODUCTION AND OBJECTIVES: Current guidelines on the treatment of blood cholesterol recommend continuous maintenance of high-intensity statin treatment in drug-eluting stent (DES)-treated patients. However, high-intensity statin treatment is frequently underused in clinical practice after stabilization of DES-treated patients. Currently, the impact of continuous high-intensity statin treatment on the incidence of late adverse events in these patients is unknown. We investigated whether high-intensity statin treatment reduces late adverse events in clinically stable patients on aspirin monotherapy 12 months after DES implantation...

BACKGROUND: Subclavian and axillary artery injuries are uncommon. In addition to many open vascular repairs, endovascular techniques are used for definitive repair or vascular control of these anatomically challenging injuries. The aim of this study was to determine the relative roles of endovascular and open techniques in the management of subclavian and axillary artery injuries comparing hospital outcomes, and long-term limb viability. METHODS: A multicenter, retrospective review of patients with subclavian or axillary artery injuries from 1/1/2004-12/31/2014 was completed at 11 participating Western Trauma Association institutions...

The main drawbacks of cardiovascular bare-metal stents (BMS) are in-stent restenosis and stent thrombosis as a result of an incomplete endothelialization after stent implantation. Nano- and microscale modification of implant surfaces is a strategy to recover the functionality of the artery by stimulating and guiding molecular and biological processes at the implant/tissue interface. In this study, cobalt-chromium (CoCr) alloy surfaces are modified via direct laser interference patterning (DLIP) in order to create linear patterning onto CoCr surfaces with different periodicities (≈3, 10, 20, and 32 µm) and depths (≈20 and 800 nm)...

BACKGROUND: Pre-clinical results of a novel open-cell, thin strut, durable polymer, laser cut cobalt chromium sirolimus-eluting stent (Angiolite) were promising. Using quantitative optical coherence tomographic (OCT) analyses, we explored the healing characteristics of the Angiolite DES system at 3- and 6-months post implantation. METHODS: A total of 103 patients with de novo coronary lesions underwent percutaneous coronary intervention with the Angiolite DES and were randomized 1:3 into two cohorts for angiographic and OCT follow-up, with 28 and 70 patients returning for 3- or 6-month post-PCI surveillance, respectively...

REVIEW
Sannette Hall, Devendra K Agrawal
Cardiovascular diseases including atherosclerosis are a major financial and health burden globally. Inflammation associated with atherosclerosis results in the development of plaques that can rupture causing thrombosis, stroke, or death. The most widely used treatment for the removal of atherosclerotic plaques is percutaneous transluminal coronary angioplasty (PTCA) with or without stenting. Although this is a safer and minimally invasive method, restenosis and intimal hyperplasia after interventional procedure remains a major hurdle and more refined approaches are needed...

Objectives The purpose of this study was to determine applicability and procedural success of bioresorbable vascular scaffolds (BVS) for percutaneous coronary intervention (PCI) in an all-comer cohort. Background BVS use in bifurcations and severely calcified lesions is not recommended, and a relatively large crossing profile may cause limitations. It is has never been studied how widely BVS can be applied in all-comer cohorts. Methods In 383 consecutive patients (acute coronary syndrome: 124, stable coronary disease 259), a BVS (Absorb) was used as first-line device unless any of the following contraindications were present: bifurcation with side branch >2...

OBJECTIVE: The objective of the study was to retrospectively evaluate the long-term clinical outcome after implantation of the self-expandable (SE) STENTYS stent in a large multicenter cohort. BACKGROUND: Incomplete stent apposition is known to cause higher rates of myocardial infarction (MI) and stent thrombosis. Because of its self-expanding features, the SE STENTYS stent adapts to the vessel wall and is therefore expected to minimize malapposition and therefore the rates of MI and stent thrombosis...

INTRODUCTION: Percutaneous coronary interventions (PCIs), such as balloon angioplasty and stent placement, are effective in the treatment of coronary artery disease. PCI has drawbacks, however, including acute thrombosis after the procedure and restenosis of the vascular lumen due to abnormal neointimal hyperplasia. ASP6537 is a selective COX-1 inhibitor that has been investigated as a possible candidate for clinical development as an antiplatelet agent. In the present study, we evaluated the in vivo antithrombotic effect of ASP6537 and its effect on neointima formation after balloon angioplasty...

BACKGROUND: Should the SYNTAX score be integrated in Interventional Cardiology? Should it really be considered as a vital decision-making tool in percutaneous coronary intervention (PCI)? To confirm the importance of this score, we aimed to systematically compare the postinterventional adverse cardiovascular outcomes which were observed in patients who were allotted a low versus a high SYNTAX score. METHODS: Randomized controlled trials and observational studies which were published from January 2007 to January 2017 were identified from MEDLINE, EMBASE, and the Cochrane databases using the searched terms 'SYNTAX score and percutaneous coronary intervention...

Recently, the use of central venous catheters (CVC) as a vascular access in patients undergoing hemodialysis is significantly increased, mainly because of the aging of this population and the presence of several comorbidities. However, the implantation and the long stay of CVC are associated with many complications. Among them, central venous stenosis represents one of the most common problems that, if not properly diagnosed, could lead to vascular thrombosis and consequent vascular access malfunction. Here, we report a case of a 38-year-old patient, who underwent hemodialysis firstly by a CVC long-term into right jugular vein and then by a prosthetic fistula in the ipsilateral limb...
