BACKGROUND: Waitlists for transcatheter aortic valve replacement (TAVR) are increasingly growing, universal criteria for prioritizing candidates are lacking, and some patients experience adverse events while awaiting the procedure. Aortic stenosis (AS)-related cardiac damage (CD) staging provides an echocardiographic framework for assessing structural CD in AS patients. We aimed to assess the correlation between CD staging and AS-related adverse events in patients awaiting TAVR.
METHODS: Waiting time for TAVR was assessed among patients with symptomatic severe AS, who were enrolled on our institutions' TAVR program during 2018-2022. The primary outcome was wait-list failure (WF), defined as AS-related hospitalizations or mortality during the waiting time for TAVR. Binary logistic regression multivariable analyses were performed to identify factors associated with WF before TAVR.
RESULTS: We included 904 AS patients (46.0% female; mean age 80.6 ± 6.8 years, mean Society of Thoracic Surgeons score 4.5 ± 2.7%). WF occurred in 72 patients (8.0%). Median waiting times were 53 (interquartile range, 35-79) days for TAVR, and 33 (interquartile range, 21-56) days until WF outcomes. Patients who experienced WF were older, with higher rates of frailty and comorbidities. On echocardiography, WF correlated with a higher CD stage. Multivariable analysis identified CD staging as an independent predictor of WF, as a continuous (hazard ratio, 1.66; 95% confidence interval, 1.15-2.42; P = 0.01) and a categorical variable (CD stage ≥ 3: hazard ratio, 2.24; 95% confidence interval, 1.07-4.71; P = 0.03). Additional predictors of WF were frailty and hypoalbuminemia.
CONCLUSIONS: Advanced CD stage is independently associated with unexpected hospitalizations and increased mortality during the waiting period for TAVR, underscoring its value in guiding candidate prioritization.
