BACKGROUND Critical limb ischemia portends a risk of major amputation of 25% to 35% within 1 year of diagnosis. Preclinical studies provide evidence that intramuscular injection of autologous CD34+ cells improves limb perfusion and reduces amputation risk. In this randomized, double-blind, placebo-controlled pilot study, we evaluated the safety and efficacy(More)
This study compared the outcomes of percutaneous coronary intervention (PCI) of saphenous vein grafts (SVGs) with drug-eluting stents (DES) with bare metal stents (BMS). PCI of degenerated SVG is associated with worse outcomes and high incidence of in-stent restenosis compared with PCI of native coronary arteries. There is a paucity of data on the outcomes(More)
OBJECTIVES This study evaluated the clinical outcomes of consecutive, selected patients treated with coronary artery bypass graft (CABG) surgery or percutaneous coronary intervention (PCI) with drug-eluting stents (DES) for unprotected left main coronary artery (ULMCA) disease. BACKGROUND Although recent data suggest that PCI with DES provides better(More)
OBJECTIVES The purpose of this study was to compare outcomes for drug-eluting stents (DES) and coronary artery bypass graft (CABG) surgery in patients with unprotected left main coronary artery (ULMCA) stenosis. BACKGROUND Expert guidelines recommend coronary artery bypass graft (CABG) surgery for the treatment of significant stenosis of the unprotected(More)
PURPOSE To compare the incidence of contrast medium-induced acute kidney injury (AKI) after intravenous (IV) administration of iodixanol for computed tomographic (CT) angiography versus intraarterial (IA) injection of iodixanol or low osmolar contrast medium (LOCM) for digital subtraction angiography (DSA) within the same population suspected of peripheral(More)
BACKGROUND Recent studies have suggested acute mitral regurgitation (MR) as a potentially serious complication of takotsubo cardiomyopathy (TTC); however, the mechanism of acute MR in TTC remains unclear. The aim of this study was to elucidate the mechanisms of acute MR in patients with TTC. METHODS AND RESULTS Echocardiography was used to assess the(More)
OBJECTIVES This study sought to investigate the immediate safety and feasibility of complete percutaneous access/closure of arteriotomy for device deployment compared to the surgical approach for transfemoral transcatheter aortic valve replacement (TAVR). BACKGROUND The percutaneous approach for arterial access for device deployment in transfemoral TAVR(More)
Patients with drug-eluting stents appear to be at increased risk of thrombosis beyond 30 days (late) or even 1 year (very late) after stent placement. Patients with recent placement of drug-eluting stents who are receiving dual-antiplatelet therapy pose a challenge in the perioperative period. Current guidelines recommend discontinuation of clopidogrel 5 to(More)
OBJECTIVES The aim of this study was to compare the procedural characteristics and outcomes of patients with acute myocardial infarction treated with drug-eluting stents (DES) vs. bare metal stents (BMS). BACKGROUND DES have been shown to reduce the incidence of restenosis and target vessel revascularization (TVR) in clinical randomized studies when(More)
BACKGROUND We report the incidence of contrast-induced acute kidney injury (CI-AKI) following administration of iodixanol or low-osmolar contrast media (LOCM) in patients for suspected peripheral arterial occlusive disease (PAOD) undergoing intra-arterial digital angiography (IA-DSA). METHODS IA-DSA was performed according to site standard for contrast(More)
