Background—Procedural and clinical outcomes still remain unfavorable for patients with long coronary lesions who undergo stent-based coronary interventions. Therefore, we compared the relative efficacy and safety of resolute zotarolimus-eluting stents (R-ZES) and sirolimus-eluting stents (SES) for patients with de novo long coronary lesions.

JACC: CARDIOVASCULAR INTERVENTIONS. Paclitaxel Drug-Coated Balloons A Review of Current Status and Emerging Applications in Native Coronary Artery De Novo Lesions

Joshua P. Loh, MBBS; Ron Waksman, MD

The paclitaxel drug-coated balloon (DCB) is an emerging device in percutaneous coronary intervention, which has shown promising results by means of a high-concentration, rapid local release of an antirestenotic drug without the use of a durable polymer or metal scaffold. DCB have already proven effective in clinical trials for the treatment of in-stent restenosis. Its coronary applications may potentially be widened to a host of complex coronary de novo lesion subsets, such as small-caliber vessels, diabetes, and diffuse lesions, where the use of stents may be hampered by suboptimal results. Recently, this technology has rapidly evolved with newer studies added to assess the value of DCB in coronary applications other than in-stent restenosis. We present a review of the role of DCB in de novo coronary lesions based on this latest clinical evidence. J Am Coll Cardiol Intv. 2012;5(10):1001-1012. doi:10.1016/j.jcin.2012.08.005.

EUROPEAN HEART JOURNAL. Prevention of stroke and systemic embolism with rivaroxaban compared with warfarin in patients with non-valvular atrial fibrillation and moderate renal impairment

Aims Patients with non-valvular atrial fibrillation (AF) and renal insufficiency are at increased risk for ischaemic stroke and bleeding during anticoagulation. Rivaroxaban, an oral, direct factor Xa inhibitor metabolized predominantly by the liver, preserves the benefit of warfarin for stroke prevention while causing fewer intracranial and fatal haemorrhages.

Aljoscha Rastan, Gunnar Tepe, Hans Krankenberg, Rainer Zahorsky, Ullrich Beschorner, Elias Noory, Sebastian Sixt, Thomas Schwarz, Klaus Brechtel, Catherine Böhme, Franz-Josef Neumann and Thomas Zeller

Aims Preliminary reports indicate that sirolimus-eluting stents reduce the risk of restenosis after percutaneous infrapopliteal artery revascularization. We conducted a prospective, randomized, multi-centre, double-blind trial comparing a polymer-free sirolimus-eluting stent with a placebo-coated bare-metal stent in patients with either intermittent claudication or critical limb ischaemia who had a de-novo lesion in an infrapopliteal artery.
