- W4220822375 abstract "I read with great interest the article by Jacobs and colleagues 1 Jacobs J.P. Shahian D.M. Badhwar V. et al. The Society of Thoracic Surgeons 2021 adult cardiac surgery risk models for multiple valve operations. Ann Thorac Surg. 2022; 113: 511-518 Abstract Full Text Full Text PDF PubMed Scopus (7) Google Scholar reporting new risk models for multiple valve operations with or without coronary artery bypass graft surgery (CABG) developed by The Society of Thoracic Surgeons (STS). Reported data (multiple valve operations with or without CABG procedures) were divided into developmental (July 2011 to June 2017; n = 35 109) and validation (July 2017 to June 2019; n = 9509) samples. An idea to validate risk model performances on the developmental database (testing the very same patients used to develop the risk score) might lead to misleading results. 2 Miller C. Another meiosis in the speciality of cardiovascular and thoracic surgery: birth of the purebred “thoracic aortic surgeon”?. J Am Coll Cardiol. 2014; 63: 1804-1806 Crossref PubMed Scopus (25) Google Scholar Therefore, I will comment only on results of the validation sample. The Society of Thoracic Surgeons 2021 Adult Cardiac Surgery Risk Models for Multiple Valve OperationsThe Annals of Thoracic SurgeryVol. 113Issue 2PreviewThe Society of Thoracic Surgeons (STS) Quality Measurement Task Force has developed risk models and composite performance measures for isolated coronary artery bypass grafting (CABG), isolated aortic valve replacement (AVR), isolated mitral valve replacement or repair (MVRR), AVR+CABG, and MVRR+CABG. To further enhance its portfolio of risk-adjusted performance metrics, STS has developed new risk models for multiple valve operations ± CABG procedures. Full-Text PDF Assessing the Performance of Risk Models With Discrimination and CalibrationThe Annals of Thoracic SurgeryVol. 115Issue 1PreviewWe thank Dr Nezic for his Letter to the Editor1 regarding The Society of Thoracic Surgeons (STS) 2021 Adult Cardiac Surgery risk models for multiple valve operations.2 The letter questions the models' discrimination, as measured by the C-statistic, and calibration, as assessed by a comparison of observed vs expected outcomes. The performance of risk models is traditionally assessed by determining the discrimination and calibration of the model.3-5 As noted by Dr Nezic, the various risk models for multiple valve with or without coronary artery bypass graft (CABG) operations2 have C-statistics ranging from 0.602 to 0.723 in different subsets of the validation sample.
