Long-Term Prognostic Value of the Society of Thoracic Surgery Risk Score in Patients Undergoing Transcatheter Aortic Valve Implantation (From the OCEAN-TAVI Registry)

Abstract The Society of Thoracic Surgeons (STS) risk model, designed to predict operative mortality after cardiac surgery, is often used for the risk assessment of patients considered for transcatheter aortic valve implantation (TAVI). We investigated the long-term prognostic value of the STS score by utilizing the data of 2588 patients undergoing TAVI from the OCEAN (Optimized CathEter vAlvular iNtervention)—TAVI Japanese multicenter registry. The patients were divided into 3 groups according to their pre-procedural STS score as follows: low-risk (STS score
