Impact of Geographic Factors on Outpatient Cardiac Rehabilitation Adherence After Transcatheter Aortic Valve Implantation

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.
