Comparison between different risk scoring algorithms on isolated conventional or transcatheter aortic valve...

Area of Science:

• Cardiology
• Cardiac Surgery
• Medical Risk Assessment

Background:

• Established risk scoring systems for cardiac surgery include EuroSCORE, STS score, and ACEF score.
• The new EuroSCORE-II has been introduced for improved risk evaluation.
• Accurate risk stratification is crucial for patient management and procedural planning.

Purpose of the Study:

• To compare the predictive accuracy of existing and new risk scores.
• To evaluate the performance of EuroSCORE, STS score, ACEF score, and EuroSCORE-II.
• To assess risk prediction in patients undergoing aortic valve replacement (AVR) and transcatheter aortic valve replacement (TAVR).

Main Methods:

• A cohort of 1,512 patients undergoing conventional AVR or TAVR was analyzed.
• Data included logistic and additive EuroSCORE, STS score, ACEF score, and EuroSCORE-II.
• Area Under the Curve (AUC) was used to assess the predictive value of each score for 30-day mortality.

Main Results:

• Overall 30-day mortality was 6.3%.
• The STS score demonstrated the highest predictive accuracy (AUC not explicitly stated but implied as best).
• EuroSCORE-II showed no superior performance compared to other models in predicting mortality for AVR and TAVR patients.

Conclusions:

• The STS score is the most effective tool for predicting 30-day mortality in AVR and TAVR patients.
• Existing risk calculators showed similar discrimination thresholds.
• The EuroSCORE-II did not offer improved risk prediction over established scores in this patient population.
