Severity of and Recovery From Anemia After Transcatheter Aortic Valve Replacement: An Analysis of the PARTNER Trials and Registries.

ABSTRACT:

Background

Anemia is associated with increased mortality in patients undergoing transcatheter aortic valve replacement (TAVR); however, data on the effect of the severity of and recovery from anemia on clinical outcomes are limited. This study examined the impact of the severity of and recovery from anemia after TAVR.

Methods

Patients with symptomatic, severe aortic stenosis across all surgical risk groups from the Placement of Aortic Transcatheter Valves (PARTNER) I, II, and III trials and registries who underwent TAVR were analyzed. Baseline anemia was defined as mild (hemoglobin [Hb] level ≥11.0 g/dL and <13.0 g/dL for men and ≥11.0 g/dL and <12.0 g/dL for women) and moderate-to-severe anemia (Hb level <11.0 g/dL). Recovery from anemia was defined as an increase of ≥1 g/d
