Many factors can influence post\u2010procedure outcomes. Traditional surgical scoring systems do not discriminate effectively. Medical parameters and functional indices can characterize mortality risk. Mobility is an important predictive functional index but is largely defined using subjective criteria.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aim<\/jats:title><jats:p>To describe the relationship between mobility, objectively defined by the requirement for gait aids to ambulate, and all\u2010cause 30\u2010day and long\u2010term mortality in patients undergoing TAVI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Mobility aid use was assessed in 1444 consecutive patients undergoing TAVI in a single center. Patients were categorized into \u201cunaided,\u201d \u201c1\u2010stick,\u201d and \u201chigher aid\u201d groups based on the Brighton Mobility Index. Mortality tracking was obtained via the NHS Spine Portal in February 2021.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Patients were aged 82 (IQR 78\u201386). 66% of patients walked unaided, 26% walked with 1 stick, and 8% required more assistance (e.g., 2 sticks, a Rollator, a Zimmer frame, or a wheelchair). Overall 30\u2010day mortality for the whole cohort was 3.5%; 1\u2010year mortality was 12.2%. Mobility was a significant predictor of 30\u2010day mortality (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.025). Use of a higher aid was associated with a mortality odds ratio of 2.83 (95% CI: 1.39\u20135.74). Mobility was also a significant predictor of long\u2010term mortality (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Odds ratios for 1\u2010stick and higher aid groups were 1.45 (95% CI: 1.21\u20131.72) and 2.01 (95% CI: 1.55\u20132.60), respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Objective assessment of mobility by gait aid use predicts both short and long\u2010term survival in patients undergoing TAVI.
