Randomized Controlled Trial Comparative StudyThe relative performance characteristics of the logistic European System for Cardiac Operative Risk Evaluation score and the Society of Thoracic Surgeons score in the Placement of Aortic Transcatheter Valves trial.
The logistic European System for Cardiac Operative Risk Evaluation (LES) score and the Society of Thoracic Surgeons (STS) score are validated to predict 30-day outcomes following surgical aortic valve replacement (SAVR) with or without coronary artery bypass grafting. Their performance when applied to patients undergoing transcatheter aortic valve replacement (TAVR) is controversial. ⋯ The STS and LES surgical risk scores overestimated 30-day/in-hospital mortality and were poor discriminators of post-TAVR mortality, but the calibration of the STS score was better in these high-risk patients. These data highlight the need for TAVR-specific risk models to optimize patient selection.
