| Popis: | Aims To assess gender differences in in-hospital mortality and 90-day readmission rates among patients undergoing transcatheter aortic valve replacement (TAVR) in the USA. Methods and results Hospitalizations for TAVR were retrospectively identified in the National readmissions database (NRD) from 2012 to 2017. Gender based differences in in-hospital mortality and 90-day readmissions were explored using multivariable logistic regression models. During the study period, an estimated 171 361 hospitalizations for TAVR were identified, including 79 722 (46.5%) procedures in women and 91 639 (53.5%) in men. Unadjusted in-hospital mortality and 90-day all-cause readmissions were significantly higher for women compared with men (2.7% vs. 2.3%, P = 0.002; 25.1% vs. 24.1%, P = 0.012, respectively). After adjusting for baseline characteristics, women had 13% greater adjusted odds of in-hospital mortality [adjusted odds ratio (aOR): 1.13, 95% confidence interval (CI): 1.02–1.26, P = 0.017], and 9% greater adjusted odds of 90-day readmission compared with men (aOR: 1.09, 95% CI: 1.05–1.14, P < 0.001). During the study period, there was a steady decrease in-hospital mortality (5.3% in 2012 to 1.6% in 2017; Ptrend < 0.001) and 90-day (29.9% in 2012 to 21.7% in 2017; Ptrend < 0.001) readmission rate in both genders. Conclusion In-hospital mortality and readmission rates for TAVR hospitalizations have decreased over time across both genders. Despite these improvements, women undergoing TAVR continue to have a modestly higher in-hospital mortality, and 90-day readmission rates compared with men. Given the expanding indications and use of TAVR, further research is necessary to identify the reasons for this persistent gap and design appropriate interventions. |
