Background Bioresorbable vascular scaffolds (BVS) offer the potential to improve long-term
outcomes of percutaneous coronary intervention after their complete bioresorption …

ContextContrast-induced nephropathy remains a common complication of radiographic
procedures. Pretreatment with sodium bicarbonate is more protective than sodium chloride …

Background Patients with obstructive left main coronary artery disease are usually treated
with coronary-artery bypass grafting (CABG). Randomized trials have suggested that drug …

Background Previous studies have established the superiority of coronary everolimus-
eluting stents over paclitaxel-eluting stents with respect to angiographic findings. However …

Background Long-term outcomes after percutaneous coronary intervention (PCI) with
contemporary drug-eluting stents, as compared with coronary-artery bypass grafting …

Background Directional coronary atherectomy is a new technique of coronary
revascularization by which atherosclerotic plaque is excised and retrieved from target …

Background In patients with coronary artery disease who receive metallic drug-eluting
coronary stents, adverse events such as late target-lesion failure may be related in part to …

Background—Intravascular ultrasound (IVUS) can assess stent geometry more accurately
than angiography. Several studies have demonstrated that the degree of stent expansion as …

Background—Randomized clinical trials have shown that a sirolimus-eluting stent
significantly reduces restenosis after percutaneous coronary revascularization. Diabetic …

Abstract Background: The Absorb everolimus-eluting poly-L-lactic acid–based
bioresorbable vascular scaffold (BVS) provides early drug delivery and mechanical support …
