EuroSCORE II and STS as mortality predictors in patients undergoing TAVI

Area of Science:

• Cardiology
• Cardiac Surgery
• Interventional Cardiology

Background:

• EuroSCORE II and STS scores are standard for risk stratification and TAVI indication.
• Their utility in predicting mortality post-TAVI remains uncertain.

Purpose of the Study:

• To assess the predictive performance of EuroSCORE II and STS for in-hospital and 30-day mortality in TAVI patients.

Main Methods:

• 59 severe aortic stenosis patients undergoing TAVI (2010-2014) were analyzed.
• Statistical tests included Student's t-test and Fisher's exact test.
• Receiver operating characteristic (ROC) curves evaluated discriminative power (AUC with 95% CI).

Main Results:

• Mean age 81±7.3 years; 42.3% male. Mean STS 20.7±10.3%, EuroSCORE II 7.6±7.3%.
• In-hospital mortality was 10.1%, 30-day mortality was 13.5%.
• Higher STS and EuroSCORE II scores were observed in non-survivors (p<0.001). STS AUC=0.81, EuroSCORE II AUC=0.77; no significant difference in discrimination (p=0.72).

Conclusions:

• STS and EuroSCORE II scores are significant predictors of mortality after TAVI.
• These scores can aid in risk assessment for patients undergoing TAVI for severe aortic stenosis.
