Patients who undergo surgery after coronary stent implantation are at risk for perioperative stent thrombosis, a highly morbid complication that can be particularly challenging to treat because the often necessary antithrombotic medications markedly increase the risk for bleeding at the surgical

Saphenous vein grafts (SVG) are used in most coronary artery bypass graft surgeries (CABG), but have high rates early and late occlusion. We sought to examine the pathogenesis of early SVG failure using serial optical coherence tomography (OCT) imaging. OCT was performed in 10 SVGs in 9 patients at

Given lower durability of endovascular superficial femoral artery (SFA) revascularization in diabetics (DM) with claudication, we performed a comparative assessment of their angiographic disease in the SFA. We conducted a blinded angiographic analysis of SFA disease in 112 consecutive patients (76

Results: Mean age was 65±1.2 years and all patients were men. Surgery occurred after a mean time of 13.9±1.7 and 8.7±2 months post stenting for noncardiac and cardiac surgery respectively. A glycoprotein IIb/IIIa inhibitor was administered preoperatively for a mean of 7.1±0.4 and 7.8±0.7 days, respectively then discontinued 4 hours before surgery. The majority of patients continued to receive aspirin through the perioperative period (33 patients for NCS group and 15 patients for cardiac surgery group). Clopidogrel was restarted as early as possible in the postoperative period. Among patients undergoing noncardiac surgery, two patients (3.9%, 95% conidence intervals 0.5%, 13.5%) had acute stent thrombosis in the immediate postoperative period and four patients had major bleeding by the GUSTO criteria. One of the cardiac surgery patients had probable stent thrombosis one hour post surgery.

BACKGROUND Daily radiation exposure over many years can adversely impact the health of medical professionals. METHODS Operator radiation exposure was recorded for 124 percutaneous coronary interventions (PCIs) performed at our institution between August 2011 and May 2013: 69 were chronic total occlusion (CTO)-PCIs and 55 were non-CTO PCIs. A disposable radiation protection sterile drape (Radpad; Worldwide Innovations & Technologies, Inc) was used in all CTO-PCI cases vs none of the non-CTO PCI cases. Operator radiation exposure was compared between CTO and non-CTO PCIs. RESULTS Mean age was 64.6 ± 6.2 years and 99.2% of the patients were men. Compared with non-CTO PCI, patients undergoing CTO-PCI were more likely to have congestive heart failure, to be current smokers, and to have longer lesions, and less likely to have prior PCI and a saphenous vein graft target lesion. CTO-PCI cases had longer procedural time (median: 123 minutes [IQR, 85-192 minutes] vs 27 minutes [IQR, 20-44 minutes]; P

There is limited data on outcomes after implantation of second generation drug-eluting stents in coronary chronic total occlusions (CTOs). Our study's aim is to evaluate the frequency of angiographic restenosis and clinical outcomes after implantation of the everolimus-eluting stent (EES) in CTOs

There are limited data regarding frequency of use and outcomes of the only approved drug coated stent (DCS; Zilver PTX®; Cook) during endovascular revascularization of infrainguinal arteries. We compared DCS to bare metal stent (BMS) use in procedures performed from January 2013 - August 2014
