Key result
Each 1-minute increase in travel time by car increased the odds of dropping out of outpatient cardiac rehabilitation by 10% in patients after transcatheter aortic valve implantation.
Why the study?
Postoperative cardiac rehabilitation improves functional outcomes after TAVI, but outpatient attendance rates in Japan remain low, limiting its benefits.
Do geographic factors affect outpatient cardiac rehabilitation adherence in patients who underwent TAVI?
Cohort (n=95)

Consider travel time when referring for outpatient CR after TAVI; extends adherence barrier evidence and supports targeted access interventions.
Background: Transcatheter aortic valve implantation (TAVI) results in shorter hospital stays and earlier discharge than conventional aortic valve replacement. Postoperative cardiac rehabilitation (CR) can improve the 6-min walk distance, activities of daily living, and mental function; however, the outpatient CR (OCR) attendance rate in Japan remains low, which limits its benefits. In this study, we investigated the effect of geographic factors on OCR adherence in patients who underwent TAVI.
Tashiro et al. (2026) conducted a cohort in Aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) (n=95). Outpatient Cardiac Rehabilitation (OCR) vs. Non-participation or dropout was evaluated on OCR dropout associated with travel time by car (per 1-min increase) (OR 1.10, 95% CI 1.01-1.20, p=0.03). Each 1-minute increase in travel time by car increased the odds of dropping out of outpatient cardiac rehabilitation by 10% in patients after transcatheter aortic valve implantation.
