Objetivos: O novo stent Biolimus-A9 (BA9) livre de polímero BioFreedom (Biossensores Europe SA, Morges, Suiça) foi estudado usando follow-ups (FU) sequenciais longitudinais por tomografia de coerência óptica (OCT). Métodos e resultados: O endpoint primário do estudo foi o percentual de cobertura das hastes do stent aos 30 dias e 9 meses por OCT. Foram realizados...

Article The TAXUS Liberté Post Approval study included patients treated with TAXUS paclitaxel DES receiving prasugrel for 12 to 30 months. Primary end point was a combination of death, infarction or stroke that resulted in 3.7% after 30 months vs. 8.8% after 12 months of prasugrel administration (p<0.001). Death and stroke rates were similar between...
This multicenter study randomized 1063 patients to receive the sirolimus-eluting stent with absorbable polymer and 1056 patients to permanent polymer stent. No differences in stent thrombosis (3.4% in the group with permanent polymer versus 2.8% in the group with absorbable polymer), target vessel revascularization (6.7% for both) or mortality (2.1% versus 2.9%; p = 0.7)....
This multicenter, prospective, randomized trial compared the Excimer laser atherectomy (Excimer Laser Atherectomy = ELA, Spectranetics, Inc.) with a balloon angioplasty in patients with in-stent restenosis in the superficial femoral artery. The injury was greater than 4 cm and the reference vessel diameter 5 to 7 mm. The mean lesion length was 19 cm, and...
The new generation drug-eluting everolimus or biolimus stents have proved superior to the first generation. However, neo intimal proliferation and late thrombosis remains a problem not yet solved same for all drug-eluting stents. The Absorb (Abbott Vascular, Abbott Park, IL, USA) is the first absorbable vascular support approved for clinical use. The EVERBIO II study...
The current recommendation for dual anti-aggregation post-DES implantation is 12 months. However, the ideal length for specific types of stents is unclear. This study aimed to evaluate the clinical non-inferiority at 3 months versus 12 months of dual anti-platelet therapy in patients undergoing coronary angioplasty with zotarolimus-eluting stents. The study randomized 1:1 to 3 months...

There is no strong evidence in the literature that the polymer type isolated (permanent or degradable) influences clinical outcomes after angioplasty and if the time of double anti-aggregation should be different with the degradable polymer. This work, with non-inferiority design, aimed to compare the sirolimus-eluting biodegradable polymer stent (Tivoli) versus the permanent polymer sirolimus-eluting stent...
