Introduction:
Surgical risk scores are widely used to identify patients at high surgical risk who may benefit from transcatheter aortic valve implantation (TAVI). A multiparametric TAVI mortality risk score based on a French registry (FRANCE-2) has recently been developed. The aim of our study was to compare the 30-day mortality prediction performance of the FRANCE-2, EuroSCORE II and STS scores.
Methods:
We retrospectively studied 240 patients from a single-center prospective registry who underwent TAVI between January 2008 and December 2015. All scores were assessed for calibration and discrimination using calibration-in-the-large and ROC curve analysis, respectively.
Results:
The observed mortality was 5.8% (n=14). The median EuroSCORE II, STS and FRANCE-2 scores were 5.0 (IQR 3.2-8.3), 5.1 (IQR 3.6-7.1) and 2.0 (IQR 1.0-3.0), respectively. Discriminative power was greater for EuroSCORE II (C-statistic 0.67) and STS (C-statistic 0.67) than for FRANCE-2 (C-statistic 0.53), but this was not statistically significant (p=0.26). All scores showed adequate calibration.
Conclusions:
All scores showed modest performance in early mortality prediction after TAVI. Despite being derived from a TAVI population, FRANCE-2 was no better than surgical risk scores in our population.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
