We sought to determine whether CSC designation is nationally associated with reported stroke rates and the potential impact on hospital performance and Transcatheter Valve Therapy National Data Registry (TVTR) public reporting.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>Consecutive TVTR cases from January 2016 through June 2023 were included, excluding sites reporting to the TVTR &lt;1 year or performing &lt;20 total TAVR procedures. The primary outcome was in-hospital stroke rate. Secondary outcomes were disabling stroke and 30-day stroke. Major bleeding, death, acute renal failure, and a composite end point were falsification end points to determine whether CSC status was uniquely associated with stroke. Multivariable hierarchical models were created starting with patient covariates and sequentially adding hospital variables to account for determinants of stroke. The impact of CSC status on hospital performance was estimated by correcting CSC hospital stroke rates in the validated TVTR 30-day composite model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      A total of 525\u2009919 TAVRs at 800 sites were included, and 10\u2009963 strokes (2.1%) were reported within 30 days: 8284 (1.6%) in-hospital and 2679 (0.5%) after discharge. A total of 4733 (0.9%) were disabling strokes. Multivariate analysis showed that CSC status and participation in TAVR trials were independent predictors of in-hospital stroke rate (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =0.033 and 0.012) and disabling stroke (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =0.033 and 0.007), but not falsification end points (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =NS).
