Despite its worldwide adoption, implementation in lower-middle-income countries such as the Brazilian public health system (SUS, acronym in Portuguese) is incipient.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Objectives:<\/jats:title>\n            <jats:p>This study aimed to evaluate TAVI exclusively within SUS patients.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods:<\/jats:title>\n            <jats:p>This was a prospective cohort study in a public tertiary hospital in southern Brazil. All patients who underwent TAVI between 2018 and 2024 were included. The cohort was divided into 2 temporal periods: from July 2018 to December 2022 (n = 60) and January 2023 to October 2024 (n = 65). The clinical and procedural characteristics and in-hospital, as well as 1 year of outcomes, were evaluated according to Valve Academic Research Consortium-2 (VARC-2) criteria.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>During the study period, 125 patients underwent TAVI. The average age was 80 years (\u00b1 10), and 49.6% were male. The mean aortic valve area was 0.76 cm\u00b2 and the mean gradient was 45 (\u00b113) mm Hg. The mean STS predicted risk of mortality (STS-PROM) score was 4.6% (\u00b13.6). Device success was achieved in 119 patients (95.2%). In-hospital mortality was 2 (1.6%). A new permanent pacemaker was required in 16 (12.8%). Demographic and clinical characteristics between the first and the second periods were similar.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n
