Key result
Discharge SBP <90 mmHg shows no link to worse 1-year mortality or HF readmission post-TAVI.
Why the study?
Changes in systemic blood pressure after TAVI have been reported, but the prognostic significance of low systolic blood pressure at discharge remains unclear.
Does low systolic blood pressure at discharge affect 1-year outcomes in older adults after TAVI?
Cohort (n=941)
No

Background: Transcatheter aortic valve implantation (TAVI) is increasingly common in older adults with severe aortic stenosis. Changes in systemic blood pressure after TAVI have been reported, however, prognostic significance of low systolic blood pressure (sBP) at discharge remains unclear.

Utsugi et al. (2025) conducted a cohort in Severe aortic stenosis (n=941). Discharge systolic blood pressure <90 mmHg vs. Discharge systolic blood pressure ≥90 mmHg was evaluated on Composite of all-cause mortality and heart failure rehospitalization (adjusted OR 1.22, 95% CI 0.41-3.64, p=0.725). Discharge systolic blood pressure <90 mmHg was not associated with a worse 1-year composite outcome of mortality and heart failure rehospitalization after TAVI (adjusted OR 1.22).
