Key result
AVR reaches only ~48% of indicated patients, dropping significantly in low-gradient disease.
Why the study?
Despite the rapid growth of aortic valve replacement for aortic stenosis, limited data suggest that symptomatic severe aortic stenosis remains undertreated.
What are the temporal trends and predictors of aortic valve replacement utilization among patients with severe aortic stenosis?
Cohort (n=10,795)
Yes
What are the temporal trends and predictors of aortic valve replacement utilization among patients with severe aortic stenosis?
Despite the growth in AVR volumes, a substantial proportion of patients with severe aortic stenosis and a clinical indication for AVR remain untreated, particularly those with low-gradient subtypes.
No takes yet. Share an insight, caveat, or question.
AVR remains underused among indicated patients, especially low-gradient AS; this observational analysis leaves open whether targeted referral improves uptake.
Li et al. (2022) conducted a cohort in Severe aortic stenosis (n=10,795). Aortic valve replacement was evaluated on Utilization of AVR among patients with an indication or potential indication. Aortic valve replacement was utilized in only 48% of patients with an indication, with significant variation by subtype ranging from 70% in high-gradient to 32% in low-gradient disease (P<0.001).
