Why the study?

Does 5-m gait speed predict 30-day mortality in patients undergoing transcatheter aortic valve replacement?

Structured PICO

Does 5-m gait speed predict 30-day mortality in patients undergoing transcatheter aortic valve replacement?

Population

8,039 patients who underwent transcatheter aortic valve replacement (November 2011-June 2014) included in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry

Intervention

5-m gait speed assessment (evaluated as continuous and categorical: slowest <0.5 m/s, slow 0.5-0.83 m/s, normal >0.83 m/s)

Comparator

Normal walkers (>0.83 m/s) or continuous comparison

Outcome

30-day all-cause mortalityhard clinical

Slower gait speed is independently associated with increased 30-day mortality after transcatheter aortic valve replacement, highlighting the importance of frailty assessment in preprocedural evaluation.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Slower gait speed may aid pre-TAVR risk stratification; extends frailty evidence but leaves practice change open pending trials.
