Abstract

BACKGROUND

: Bioresorbable vascular scaffolds (BVS) were developed to improve the long-term results of percutaneous coronary intervention, restoring vasomotion.

OBJECTIVES

: To report very late follow-up of everolimus-eluting Absorb BVS (Abbott Vascular, Santa Clara, USA) in our center.

METHODS

: Observational retrospective study, in a single Brazilian center, from August 2011 to October 2013, including 49 patients submitted to Absorb BVS implantation. Safety and efficacy outcomes were analyzed in the in-hospital and very late follow-up phases (> 2 years).

RESULTS

: All 49 patients underwent a minimum follow-up of 2.5 years and a maximum of 4.6 years. Mean age was 56.8 ± 7.6 years, 71.4% of the patients were men, and 26.5% were diabetic. Regarding clinical presentation, the majority (94%) had stable angina or silent ischemia. Device success was achieved in 100% of cases with 96% overall procedure success rate. Major adverse cardiovascular events rate was 4% at 30 days, 8.2% at 1 year, and 12.2% at 2 years, and there were no more events until 4.6 years. There were 2 cases of thrombosis (1 subacute and 1 late).

CONCLUSIONS

: In this preliminary analysis, Absorb BVS showed to be a safe and effective device in the very late follow-up. Establishing the efficacy and safety profiles of these devices in more complex scenarios is necessary.

FUNDAMENTO

: Os suportes vasculares bioabsorvíveis (SVB) foram desenvolvidos com o intuito de melhorar os resultados da intervenção coronária percutânea a longo prazo, restabelecendo-se a vasomotricidade.

OBJETIVOS

: Reportar o seguimento muito tardio do implante do SVB eluidor de everolimus Absorb® (Abbot Vascular, Santa Clara, EUA) em nosso centro.

MÉTODOS:: Estudo observacional, retrospectivo, em um único centro brasileiro, que incluiu 49 pacientes submetidos ao implante do SVB Absorb® entre agosto/2011 e outubro/2013. Foram analisados os desfechos de segurança e eficácia na fase hospitalar e bastante tardia (> 2 anos).

RESULTADOS

: Todos os 49 pacientes completaram um seguimento mínimo de 2,5 anos, sendo o máximo de 4,6 anos. A média de idade foi 56,8 ± 7,6 anos, sendo 71,4% da população estudada do sexo masculino e 26,5% composta por diabéticos. Considerando a apresentação clínica, a grande maioria (94%) tinha angina estável ou isquemia silenciosa. Obteve-se sucesso do dispositivo em 100% dos casos e do procedimento, em 96%. A taxa de eventos cardiovasculares maiores foi de 4% aos 30 dias, de 8,2% em 1 ano, e de 12,2% em 2 anos, sem mais eventos até 4,6 anos. Houve 2 casos de trombose (1 subaguda e 1 tardia) até o último seguimento.

CONCLUSÕES:: Nesta análise preliminar, o uso do SVB Absorb® mostrou-se seguro e eficaz no seguimento bastante tardio. Faz-se necessário estabelecer o perfil de eficácia e segurança destes dispositivos em cenários de maior complexidade.

摘要

背景

生物可吸收血管支架(BVS)旨在改善经皮冠状动脉介入治疗的长期效果,恢复血管运动功能。

目的

报告我院对依维莫司洗脱Absorb BVS(美国雅培血管公司,圣克拉拉)的极晚期随访情况。

方法

这是一项在巴西单中心进行的观察性回顾性研究,研究时间为2011年8月至2013年10月,纳入49例行Absorb BVS植入术的患者。分析住院期和极晚期随访阶段(>2年)的安全性和有效性结果。

结果

49例患者均接受了至少2.5年、最长4.6年的随访。平均年龄为56.8±7.6岁,71.4%为男性,26.5%为糖尿病患者。临床表现方面,大多数(94%)为稳定型心绞痛或无症状性心肌缺血。器械成功率为100%,总体手术成功率为96%。30天时主要不良心血管事件发生率为4%,1年时为8.2%,2年时为12.2%,至4.6年时无更多事件发生。有2例血栓形成(1例亚急性,1例晚期)。

结论

在这项初步分析中,Absorb BVS在极晚期随访中显示出安全有效。有必要在更复杂的情况下确定这些器械的有效性和安全性。

背景

生物可吸收血管支架(SVB)的研发目的是改善经皮冠状动脉介入治疗的长期效果,并恢复血管舒缩功能。

目的

报告我院对依维莫司洗脱Absorb® SVB(美国雅培血管公司,圣克拉拉)的极晚期随访情况。

方法

这是一项在巴西单中心进行的观察性回顾性研究,纳入2011年8月至2013年10月间49例行Absorb® SVB植入术的患者。分析住院期和极晚期随访阶段(>2年)的安全性和有效性结果。

结果

49例患者均接受了至少2.5年、最长4.6年的随访。平均年龄为56.8±7.6岁,71.4%为男性,26.5%为糖尿病患者。临床表现方面,大多数(94%)为稳定型心绞痛或无症状性心肌缺血。器械成功率为100%,手术成功率为96%。30天时主要心血管事件发生率为4%,1年时为8.2%,2年时为12.2%,至4.6年时无更多事件发生。至末次随访时共有2例血栓形成(1例亚急性,1例晚期)。

结论

在这项初步分析中,使用Absorb® SVB在极晚期随访中显示出安全有效。有必要在更复杂的情况下确定这些器械的有效性和安全性。
