Resumo Fundamento Ensaios clínicos randomizados (ECRs) e estudos observacionais compararam a eficácia e a segurança do implante valvar transcateter (TAVR) e da substituição cirúrgica da valva aórtica (SAVR) em pacientes com estenose aórtica grave. Objetivos Comparar TAVR e SAVR em pacientes com diferentes riscos cirúrgicos, características da população e diferentes válvulas protéticas transcateter. Métodos Uma overview das revisões sistemáticas (RSs) foi realizada seguindo um protocolo estruturado. Os resultados foram agrupados por risco cirúrgico, características da população e diferentes válvulas. Os ECRs foram reanalisados por meio de metanálises nas RSs, e os resultados foram resumidos por meio do método GRADE. O nível de significância estatística adotado foi de 5%. Resultados Em comparação com a SAVR, os pacientes com alto risco cirúrgico submetidos à TAVR tiveram um risco menor de ( odds ratio , intervalo de confiança de 95%, diferença absoluta de risco) fibrilação atrial (FA) (0,5, 0,29-0,86, -106/1000) e hemorragia com risco à vida (0,29, 0,2-0,42, -215/1000). Pacientes com risco cirúrgico intermediário apresentaram menor risco de FA (0,27, 0,23-0,33, -255/1.000), hemorragia com risco à vida (0,15, 0,12-0,19, -330/1.000) e insuficiência renal aguda (IRA) (0,4, 0,26-0,62, -21/1000). Pacientes com baixo risco cirúrgico tiveram menor risco de morte (0,58, 0,34-0,97, -16/1000), acidente vascular encefálico (AVE) (0,51, 0,28-0,94, -15/1000), FA (0,16, 0,12-0,2, -295/1000), hemorragia com risco à vida (0,17, 0,05-0,55, -76/1000) e IRA (0,27, 0,13-0,55, -21/1000) e tiveram maior risco de implante de marca-passo definitivo (IMD) (4,22, 1,27 -14.02, 141/1000). Os dispositivos de geração mais recente tiveram um risco menor de FA em comparação com as gerações mais antigas, e pacientes usuários de dispositivos expansíveis por balão não apresentaram riscos maiores de IMD. Conclusões Este artigo apresenta evidências de que pacientes com risco cirúrgico baixo, intermediário e alto apresentam melhores desfechos quando tratados com TAVR em comparação com a SAVR.

Abstract Background Randomized controlled trials (RCTs) and observational studies have compared the efficacy and safety of transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) in patients with severe aortic stenosis. Objectives Compare TAVR and SAVR in patients with different surgical risks, population characteristics, and different transcatheter prosthetic valves. Methods An overview of systematic reviews (SRs) was conducted following a structured protocol. Results were grouped by surgical risk, population characteristics, and different valves. RCTs in the SRs were reanalyzed through meta-analyses, and the results were summarized using the GRADE method. The adopted level of statistical significance was 5%. Results Compared to SAVR, patients with high surgical risk using TAVR had a lower risk of (odds ratio, 95% confidence interval, absolute risk difference) atrial fibrillation (AF) (0.5, 0.29-0.86, -106/1000) and life-threatening bleeding (0.29, 0.2-0.42, -215/1000). Patients with intermediate surgical risk had a lower risk of AF (0.27, 0.23-0.33, -255/1000), life-threatening bleeding (0.15, 0.12-0.19, -330/1000), and acute renal failure (ARF) (0.4, 0.26-0.62, -21/1000). Patients with low surgical risk had a lower risk of death (0.58, 0.34-0.97, -16/1000), stroke (0.51, 0.28-0.94, -15/1000), AF (0.16, 0.12-0.2, -295/1000), life-threatening bleeding (0.17, 0.05-0.55, -76/1000), and ARF (0.27, 0.13-0.55, -21/1000), and had a higher risk of permanent pacemaker implantation (PPI) (4.22, 1.27-14.02, 141/1000). Newer generation devices had a lower risk of AF than older generations, and patients using balloon-expandable devices did not experience higher risks of PPI. Conclusions This paper provides evidence that patients at low, intermediate, and high surgical risks have better outcomes when treated with TAVR compared with SAVR.
