Courtesy of Dr. Rodrigo Abreu. INTRODUCTION Bifurcation lesion treatment has evolved considerably in the last years: from balloon angioplasty (with high occlusion and restenosis rates) to bare metal stent angioplasty (with a procedural success around 86% and major adverse cardiac events [MACE] at 1 year around 32%). The subsequent emergence of drug-eluting stents (DES) reduced...

Fundamentos: Dados recentes de metanálise tem levantado dúvidas com relação a segurança dos stents eluidores de fármacos com polímero biodegradável (BP-DES) quando comparados aos stents eluidores de fármacos com polímero durável (DP-EES). O NOBORI® Biolimus-Eluting Stent (BP-BES) versus XIENCE® / PROMUS® (DP-DES) Everolimus-Eluting Stent Trial (NEXT Trial) é um estudo randomizado de 98 centros, realizado...
This randomized, controlled, multicenter and blind study compared the second generation of bio-absorbable stent platform with the everolimus-eluting Xience. 501 patients were randomized 2: 1 (Absorb / Xience) with de novo lesions in native coronary arteries with a reference diameter between 2.25 and 3.8 mm estimated by quantitative angiography. All the patients underwent IVUS and...
This multicenter work from Japanrandomized 3200 patients to receive biodegradable polymer biolimus eluting stent(Nobori) or everolimus-eluting stent with permanent polymer (Xience / Promus). The primary end point for efficacy was any revascularizationlesion. A two year follow up the Nobori stent was non-inferior to death or myocardial infarction (7.83% versus 7.69%) and TLR (6.23% versus 5.95%). ...
Spanish-Portuguese multicentre CIBELES study (Raul Moreno, Madrid, Spain) compared two drug-eluting stents – an everolimus (Xience V, Abbott Vascular, USA) and a sirolimus-releasing eluting stent (Cypher Select, Cordis Corporation, Miami Lakes, Florida, USA) in the context of total chronic coronary occlusions. With a non-inferiority design, the study randomized 208 patients (1:1), using as the primary...

Short dual antiplatelet therapy (DAPT) has shown benefits in patients receiving drug eluting stents (DES), reducing bleeding with no concomitant increase in major adverse cardiovascular events (MACE). Traditionally, the therapeutic window was limited to monotherapy with P2Y12 inhibitors during the first year and there are few data on short DAPT followed by long term monotherapy...
For many years, percutaneous transluminal coronary angioplasty (PCTA) has expanded significantly worldwide. However, despite the demonstrated advantages of intravascular ultrasound (IVUS) in terms of minimal luminal area, reduced cardiovascular events, and restenosis, its use is not very common due to various reasons. On the other hand, optical coherence tomography (OCT) offers even higher resolution than...
