Clinical Impact of Hypoattenuating Leaflet Thickening After Transcatheter Aortic Valve Replacement

Abstract

In a large, real-world cohort of patients receiving TAVR followed by systematic screening with CTA 30-days post-procedure, HALT was found in 12% of patients and independently associated with long-term mortality. Findings of this nonrandomized, observational cohort study require independent validation.
