We assessed the costs of index hospitalization and subsequent healthcare utilization, categorizing the cohort into 6 age subgroups: <70, 70-74, 75-79, 80-84, 85-89, and ≥90 years. The median follow-up periods were 2.5 and 3.0 years in the TAVI and SAVR groups, respectively.<h4>Results</h4>The index hospitalization costs were 41.0 million Korean won (KRW) (interquartile range [IQR], 39.1-4Journal of chest surgeryCosts Associated with Transcatheter Aortic Valve Implantation and Surgical Aortic Valve Replacement in Korea.PMC11538586HC21C0180010021Lim CShinn SHLee SHSohn SHKim KHChoi JWKang YYoo JSfalseCosts Associated with Transcatheter Aortic Valve Implantation and Surgical Aortic Valve Replacement in Korea.<h4>Background</h4>This study compared the costs associated with transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) in Korea by utilizing the National Health Insurance Service database.<h4>Methods</h4>Between June 2015 and May 2019, 1,468 patients underwent primary isolated transfemoral TAVI, while 2,835 patients received primary isolated SAVR with a bioprosthesis.
