Abstract

Objective: The study was designed to validate euroSCORE II and ACEF (age, creatinine, and ejection fraction) scores in patients undergoing isolated or associated mitral valve surgery and compare them with logistic euroSCORE and Society of Thoracic Surgeons scores. Methods: Data on 3441 consecutive patients undergoing isolated or associated mitral valve surgery in a 6-year period were retrieved from 3 prospective institutional databases. Discriminatory power was assessed with the C index. Calibration was evaluated with calibration curves and associated statistics. Results: In-hospital mortality was 3.4%. Discriminatory power was uniformly good (for euroSCORE II: area under curve, 0.79; 95% confidence interval, 0.74-0.84; for logistic euroSCORE: area under the curve, 0.78; 95% confidence interval, 0.74-0.83; for ACEF: area under the curve, 0.73; 95% confidence interval, 0.69-0.79) but significantly higher in euroSCORE models (P
