RecruitingBehavioural interventionCardioHeartConnect: Commercially Available Fitness for Cardiac RehabilitationThis trial evaluates the effectiveness of CardioHeartConnect, an eight-week mobile cardiac rehabilitation intervention using Peloton fitness modules, compared to educational control among patients recovering from transcatheter aortic valve replacement (TAVR). The study aims to improve physical activity, functional capacity, quality of life, and cardiovascular health using wearable devices and a digital engagement platform. A total of 200 patients will be recruited from the UCHealth Structural Heart and Valve Clinic and randomized to either CardioHeartConnect or CardioHeartEd. Participants will be assessed at baseline, 8 weeks, and 12 months using surveys, smartwatch data, and electronic health records.
