- Abstract
Background: Transcatheter aortic valve implantation (TAVI) is a well-established treatment for symptomatic patients with aortic stenosis. Yet, the impact of sex differences and public vs. private procedural setting on TAVI outcomes remain uncertain., Methods: The RIBAC-NT (Brazilian Registry for Evaluation of Transcatheter Aortic Valve Replacement Outcomes) dataset included 3194 TAVI patients from 2009 to 2021. This retrospective analysis explored disparities in baseline characteristics, procedural and in-hospital outcomes stratifying patients by sex and procedural setting. Temporal trends were also investigated., Results: We included 1551 (49 %) female and 1643 (51 %) male patients. Women were older (83 [78-87] vs. 81 [75-85] years; p < 0.01) but had a lower prevalence of diabetes mellitus (30.2 % vs. 36.3 %, p < 0.01) and coronary artery disease (39.0 % vs. 52.2 %, p < 0.01). However, women had a 3-fold higher higher risk of life-threatening bleeding (6.1 % vs. 2.4 %, p < 0.01). Women presented higher procedural and in-hospital mortality rates (4.4 % vs. 2.5 % and 7.7 % vs. 4.5 %, all p < 0.01, respectively). Although public hospitals presented ~2-fold higher procedural mortality rate compared with private settings (5.0 % vs. 2.7 %, p < 0.01), after multivariable analysis procedural setting was not independently associated with in-hospital mortality., Conclusions: Women had higher procedural and in-hospital mortality rates after TAVI as compared with men, while facing higher life-threatening bleeding and adverse events rates. Although public hospitals exhibited higher mortality rates than private centers, procedural setting was not independently associated with in-hospital mortality., Competing Interests: Declaration of competing interest Dr. de Brito has served as proctor for Edwards LifeSciences and Medtronic.
