Why Surgical Risk Algorithms Are Not Predictive of Transcatheter Aortic Valve Replacement Outcomes!
Key result
Observed 1-year mortality rates after TAVR were substantially lower than predicted by the Logistic EuroSCORE, with an observed/predicted mortality ratio ranging from 0.12 to 0.26.

Implication
Surgical risk algorithms developed for SAVR are inaccurate for TAVR and should be replaced by TAVR-specific risk models for quality assessment and risk prediction.
Structured PICO
Are surgical risk algorithms predictive of outcomes in patients undergoing transcatheter aortic valve replacement?
P
Population
1,785 patients with severe aortic stenosis treated with the Sapien 3 transcatheter heart valve in a European registry.
E
Exposure
Surgical risk algorithms (Logistic EuroSCORE, STS Predicted Risk of Mortality)
O
Outcome
Accuracy of mortality prediction
Main Result
Effect estimate: observed/predicted mortality ratio 0.12 to 0.26
Surgical risk algorithms developed for SAVR are inaccurate for TAVR and should be replaced by TAVR-specific risk models for quality assessment and risk prediction.

Mack et al. (2019) conducted an editorial in Severe aortic stenosis (n=1,785). Transcatheter aortic valve replacement (TAVR) vs. Logistic EuroSCORE predicted mortality was evaluated on 1-year all-cause mortality (observed/predicted mortality ratio 0.12 to 0.26). Observed 1-year mortality rates after TAVR were substantially lower than predicted by the Logistic EuroSCORE, with an observed/predicted mortality ratio ranging from 0.12 to 0.26.
