Transcatheter Aortic Valve Implantation In Patients With Severe Aortic Stenosis Hospitalized

This study was attempted to evaluate the effect of transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis hospitalized with acute heart failure. Researchers assembled a consecutive cohort including a total of 1,547 patients with severe aortic stenosis undergoing TAVI, where the acute heart failure (AHF) status at admission was collected; patients were divided into AHF and elective TAVI groups. Early TAVI was defined as TAVI performed ≤ 60 hours after emergency room arrival in the AHF group. All-cause mortality at 30 days and 2 years after TAVI was the primary outcome. The results indicated that in patients with AHF, TAVI was correlated with worse short and long-term outcomes. Early TAVI did not significantly lower all-cause mortality at 30 days in the AHF setting; nevertheless, it exhibited a strong trend for lower all-cause mortality at 2-year.
