RESUMO

Introdução:

O stent Orsiro é um stent híbrido que possui revestimentos passivo (carbeto de silício amorfo)e ativo (ácido poli-L-lático, PLLA). O primeiro encapsula as hastes do stent, promovendo menor inflamação local, e o segundo libera o sirolimus por meio de matriz biodegradável. Nosso objetivo foi comparar os resultados das intervenções coronárias percutâneas (ICP) dos stents Orsiro e Xience® V (eluidor de everolimus) na prática clínica diária.

Métodos:

Estudo observacional em que os pacientes foram alocados em dois grupos os que e ceberam exclusivamente um ou mais stents Orsiro e os que receberam exclusivamente stents Xience® V. Desfechos iniciais e tardios foram prospectivamente coletados.

Resultados:

Entre setembro de 2012 e março de 2014, incluímos 92 e 108 pacientes tratados com stent Orsiro e Xience® V, respectivamente. Características clínicas, angiográficas e do procedimento foram, em sua maioria, semelhantes entre os grupos. As taxas de sucesso do procedimento (98,9% vs. 95,4%; p = 0,22), mortalidade (1,1% vs. 0%; p = 0,40) e trombose do stent (0% vs. 0,9%; p = 0,30) hospitalares não diferiram entre os grupos. O tempo de seguimento foi de 434 ± 111 e 477 ± 66 dias (p = 0,23), respectivamente, não sendo observadas diferenças na mortalidade (0,9% vs. 0%; p = 0,30), trombose do stent (0% vs. 0,9%; p = 0,30)e nem na necessidade de revascularização da lesão alvo (0% vs. 0,9%; p = 0,30).

Conclusões:

Os stents Orsiro e Xience® V apresentaram desempenho semelhante, com baixas taxas de eventos clínicos e angiográficos iniciais e tardios.
ABSTRACT

Background:

The Orsiro is a hybrid stent which has passive (amorphous silicon carbide) and active(poly-L-lactic acid, PLLA) coatings. The first layer encapsulates the stent struts, promoting lower local inflammation, where as the second layer releases sirolimus through a biodegradable matrix. This study’saim was to compare the results of percutaneous coronary interventions (PCI) with Orsiro and Xience™ Vstents (everolimus-eluting stent) in daily clinical practice.

Methods:

Observational study in which patients were divided into two groups those who received only one or more Orsiro stents, and those who received only XienceTM V stents. Early and late outcomes were prospectively collected.

Results:

Between September 2012 and March 2014, this study included 92 and 108 patients treated with Orsiro and Xience™ V stents, respectively. Clinical, angiographic, and procedure characteristics were mostly similar between groups. Rates of procedure success (98.9% vs. 95.4%; p = 0.22), in-hospital mortality (1.1% vs. 0%; p = 0.40) and stent thrombosis (0% vs. 0.9%, p = 0.30) did not differ between groups. Time of follow-up was 434 ± 111 and477 ± 66 days (p = 0.23), respectively, and differences in mortality (0.9% vs. 0%, p = 0.30), stent thrombosis (0% vs.0.9%; p = 0.30), or need for repeat revascularization of the target lesion (0% vs. 0.9%; p = 0.30) were not observed.

Conclusions:

Orsiro and Xience™ V stents showed similar performance, with low rates of early and late clinical and angiographic events.
