AIM: To evaluate gender differences and mortality trends in a population undergoing transcatheter aortic valve implantation (TAVI) and to analyze the correlates to all-cause mortality at follow-up. METHODS: The study comprises a prospective cohort of 592 TAVI patients (53.4% female) treated between 2008 and 2018. Mortality differences between genders at different timepoints were assessed according to log rank test. Predictors of all-cause mortality at follow-up were identified using a univariate model and were then analyzed through multivariate Cox proportional hazard models. RESULTS: Compared with female patients, males were younger (81 ± 7.5 years vs 84.3 ± 5.3 years) and presented more comorbidities. Twelve female and 8 male patients (3.5%) died in the first 30 days after TAVI. Despite a higher Society of Thoracic Surgeons (STS) score in women, all-cause mortality rates at 30 days and 1 year were comparable. At long-term follow-up, female patients demonstrated better survival rates, despite a higher number of periprocedural complications. Correlates identified in men were the presence of diabetes and previous history of coronary artery bypass grafting, New York Heart Association class III/IV, pulmonary artery systolic pressure, and non-transfemoral access. None of these variables remained significant in the multivariable analysis. In females, only peripheral artery disease was associated with mortality. Shock and need for renal replacement were predictors of mortality in both genders, as was heart failure readmission after discharge. STS score was also shown to correlate with long-term mortality in both genders. CONCLUSION: Despite a higher STS score in women, 30-day mortality was not significantly different from men, while women present better clinical outcomes at long-term follow-up.
