Why the study?
Do current risk scores (EuroSCORE, STS, Ambler) accurately predict operative mortality in patients with valvular heart disease?
Do current risk scores (EuroSCORE, STS, Ambler) accurately predict operative mortality in patients with valvular heart disease?
Current surgical risk scores should be interpreted with caution in patients with valvular heart disease due to poor calibration for individual operative mortality.
Answers are grounded in this paper and cite their sources.
Risk scores warrant cautious use for individual valvular surgery decisions; confirms poor calibration despite good discrimination.

Rosenhek et al. (2011) conducted a review in Valvular heart disease. Risk scores (EuroSCORE, STS, and Ambler score) was evaluated on Predictive ability and exact operative mortality estimation. Current risk scores (EuroSCORE, STS, Ambler) provide good discrimination but cannot reliably estimate exact operative mortality in individual patients with valvular heart disease.
