ABSTRACT
AIMS: Access to transcatheter aortic valve replacement (TAVR) is generally prioritized for symptomatic patients presenting with severe heart failure, syncope, angina, and decrease in left ventricular ejection fraction <40%. However, a substantial number of patients die while awaiting TAVR. In response to rising demand driven by an ageing population, it is essential to stratify interventions, as proposed by Généreux's Aortic Stenosis staging.
METHODS AND RESULTS: We conducted a retrospective, single-center, longitudinal study in patients referred for TAVR. We specifically analysed the characteristics of 98 patients who died while on the TAVR waiting list. The primary outcome was all-cause mortality from the time of a patient's inclusion on the TAVR waiting list or non-proceeding to TAVR. The overall proportion of deceased patients was 8.4% [95% confidence interval (CI), 6.9-10.1] and 4% when excluding deaths occurring after 2019. By 3 months, 61.2% of patients had undergone TAVR, and this increased to 85.4% at 6 months. Deaths occurred in 6.3% of patients by 3 months and 7.8% by 6 months. We notice that 90% of deaths took place within the first 3 months. Multivariable analysis identified several variables independently associated with mortality on the TAVR waiting list: prior myocardial infarction [subdistribution hazard ratio (sHR), 1.87 (95% CI, 1.12-3.13); P = 0.017] and pulmonary artery systolic pressure > 60 mmHg [sHR, 2.37 (95% CI, 1.36-4.12); P = 0.002]. Généreux stages 3 and 4 showed a strong association with waiting-list mortality, more than doubling the risk of death [sHR, 2.12 (95% CI, 1.33-3.38); P = 0.002].
CONCLUSION: These findings suggest that TAVR candidates at Généreux stages 3 and 4 should receive higher priority on the waiting list.
