In this study, we evaluated whether differences in care delivery between MA and fee-for-service (FFS) Medicare contribute to cardiovascular outcomes after transcatheter aortic valve replacement (TAVR).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>Medicare patients who underwent TAVR from January 1, 2018, to December 31, 2022, were eligible for cohort inclusion. TAVR utilization rates in MA and FFS were calculated as the age- and sex-standardized number of procedures per 10\u2009000 person-years. Patient characteristics were compared between MA and FFS using standardized mean differences (SMDs), with an SMD \u226510 considered meaningful. The association of MA versus FFS enrollment with 30-day and 1-year outcomes was assessed using logistic and Cox regression models, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      Among the 317\u2009630 patients (64.4% FFS, 35.6% MA) undergoing TAVR, the mean age was 80.6\u00b17.0 years, and 55.1% were male. TAVR utilization rates were similar between MA and FFS, with 11.2 TAVRs\/10\u2009000 person-years in FFS compared with 11.7 TAVRs\/10\u2009000 person-years in MA by the end of the study. Compared with FFS patients, MA patients were more likely to be Black (5.4% versus 3.0%; SMD, \u221211.9) and dual-enrolled in Medicaid (13.7% versus 8.6%; SMD, \u221216.3). Comorbidity profiles were similar (SMD,\n                      <jats:italic toggle=\"yes\">&lt;<\/jats:italic>\n                      10). In the comorbidity-adjusted model, MA patients had lower odds of 30-day death (adjusted odds ratio, 0.90 [95% CI, 0.86\u20130.95]). At 1 year, MA patients had a lower adjusted risk of death (hazard ratio, 0.94 [95% CI, 0.92\u20130.96]), all-cause readmission (hazard ratio, 0.86 [95% CI, 0.85\u20130.88]), stroke (hazard ratio, 0.90 [95% CI, 0.87\u20130.94]), and aortic valve reintervention (hazard ratio, 0.86 [95% CI, 0.76\u20130.96]).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>Despite similar clinical profiles and TAVR utilization, MA patients appeared to experience better 30-day and 1-year outcomes than FFS patients.
