TAVI is associated with a significantly lower rate of the primary composite endpoint compared to SAVR in patients with low surgical risk.
Does TAVI provide safe and non-inferior outcomes compared to SAVR in patients with aortic stenosis across different surgical risk profiles?
This review highlights that recent large RCTs support the safety and non-inferiority of TAVI compared to SAVR even in low-risk patients, influencing current ESC guidelines.
Effect estimate: HR 0.54 (95% CI 0.37-0.79)
Absolute Event Rate: 8.5% vs 15.1%
p-value: p=<0.001
Aortic stenosis (AS) is the most common valvular disease requiring surgical (SAVR) or transcatheter intervention (TAVI) in Europe and North America. The first TAVI was performed in 2002 in order to find clinical application in a short period of time, and the initial ESC guidelines recommended this procedure in patients with a high risk of SAVR. ESC guidelines for the treatment of valvular diseases from 2021, the decision on the treatment modality of AS is defined by the Heart team, and SAVR is recommended in younger patients with a low risk of surgery (75 years STS-PROM/EuroScore II4%), and TAVI is recommended in elderly patients ≥75 years or in patients with high operative risk (STSPROM/EuroScore II8%) or in patients not suitable for surgery. On the other hand, large randomized clinical studies (The PARTNER 3, Evolut Low Risk and NOTION studies) showed that TAVI is safe even for patients with a low operative risk (STS-PROM/EuroScore II4%) and that it is not inferior to SAVR (UK TAVI trial).
Nedeljković et al. (2022) conducted a review in Aortic Stenosis (AS). Transcatheter Aortic Valve Implantation (TAVI) vs. Surgical Aortic Valve Replacement (SAVR) was evaluated on Composite of death, stroke, or rehospitalization at 1 year (HR 0.54, 95% CI 0.37-0.79, p=<0.001). TAVI is associated with a significantly lower rate of the primary composite endpoint compared to SAVR in patients with low surgical risk.
