Although drug-eluting stents have dramatically reduced angiographic restenosis and clinical need for repeat revascularization procedures, some adverse effects, such as late stent thrombosis, have been described. We evaluated clinical performance of paclitaxel-eluting stents coated with a new bioactive polymer system (P-5) based on a copolymer of an acrylic derivative of triflusal in patients with coronary artery disease.

Several complications have been reported regarding the percutaneous closure of secondary atrial septal defects such as erosion, thromboembolic events, arrhythmias, and endocarditis. In this report, we describe the case of a 75-year-old woman who underwent percutaneous closure of a secondary atrial septal defect with a 12 mm Amplatzer septal occluder. Six months after the uneventful implantation of the device, we manifested an asymptomatic late embolization of the device in the abdominal aorta. The device was surgically retrieved.

Patients with an indwelling Impella may require escalation of hemodynamic support or exchange to another circulatory assistance platform. As such, preservation of vascular access is preferable in cases where anticoagulation cannot be discontinued or to facilitate exchange to an alternative catheter or closure device. Challenges exist in avoiding bleeding and loss of wire access in these situations. We describe a single-access “Trojan Horse” technique that minimizes bleeding while maintaining arterial access for rapid exchange of this percutaneous ventricular assist device.

The incidence of contrast-induced acute kidney injury (CI-AKI) is particularly high in patients with severe chronic kidney disease (CKD). Novel contrast-sparing strategies are warranted to guarantee the benefit of revascularization in this challenging and growing patient population. We aimed to evaluate the feasibility of an ultra-low contrast volume percutaneous coronary intervention (ULC-PCI) protocol in patients with severe CKD.

We present the indications for use, temporal trends, complications, and 1-year clinical outcomes after single-access percutaneous mechanical circulatory support device placement from years 2009-2015 at our institution.

The aim of this study was to determine the differences in lead failure mechanisms across the major United States implantable defibrillator lead manufacturers (Boston Scientific, Medtronic, and St. Jude Medical), between all non-recalled and recalled leads, and between two recalled lead families (Medtronic Sprint Fidelis and the St. Jude Medical Riata and Riata ST).

An isolated posterior myocardial infarction (PMI) is associated with significant morbidity and mortality. Because physicians often fail to recognize this diagnosis, there may be delays in the timely revascularization of these patients. The present study sought to identify the clinical characteristics and reperfusion times among patients presenting with isolated PMI.

This study sought to quantify depression rates in patients referred for percutaneous coronary intervention (PCI) for chronic total occlusion (CTO), assess its relationship to baseline angina symptoms, and compare angina improvement after CTO-PCI between depressed and non-depressed patients.

Google Glass (Google, Inc) is a voice-activated, hands-free, optical head-mounted display device capable of taking pictures, recording videos, and transmitting data via wi-fi. In the present study, we examined the accuracy of coronary angiogram interpretation, recorded using Google Glass.

We performed a systematic review and meta-analysis of existing studies from the literature comparing robotically assisted (RA) percutaneous coronary intervention (PCI) to manual PCI (M-PCI).
