The vast majority of cardiac rehabilitation eligible individuals do not participate in center based cardiac rehabilitation (CBCR). While steps to encourage participation in CBCR are important, many individuals will still not participate for a variety of reasons. This randomized controlled trial is evaluating a home-based cardiac rehabilitation (HBCR) intervention delivered using a custom app and digital tools in patients undergoing transcatheter heart valve interventions (THVIs). After a brief roll-in period, participants not intending to participate in CBCR are randomized to one of three groups: (1) control, (2) HBCR mobile health intervention with hands-off delivery, and (3) HBCR mobile health intervention with interactive delivery. Participants in the intervention groups (hands-off/interactive delivery) will also be randomized to continue the intervention for 12 weeks or 24 weeks. The intervention targets key health behaviors and includes traditional cardiac rehabilitation components. The study will assess the effect of the intervention on clinical events, physical activity, quality of life, and other outcomes. Those who intend to participate in CBCR will be followed in a registry.

| Measure | Description | Time Frame |

| Probability of the hierarchical clinical event composite | The hierarchical clinical event composite includes (in order of hierarchy): (1) all-cause death; (2) all-cause hospitalization; and (3) skilled nursing facility visits. To examine whether the intervention improves mortality, hospitalization, and SNF rates after THVIs, we will conduct Bayesian Markov longitudinal proportional odds model on weekly outcome measures. The pooled active treatment vs. control group comparison (primary comparison for the trial) will be estimated by contrasting the average of posterior probability that Y≥y of the two active treatment groups (hands-off HBCR and interactive HBCR) to the control group. | Over the entire available follow-up period for randomized participants (minimum of 6 months, maximum approximately 24-30 months). |
| Average daily total activity counts | Daily total activity counts are determined by a triaxial actigraphy device. | The actigraphy device will be worn for approximately one week and, using data from days when the device was worn >10 hours, the average daily total activity counts determined. The primary comparison will be at 12 weeks after randomization. |
| Measure | Description | Time Frame |
|---|---|---|
| Average daily total activity counts | Daily total activity counts are determined by a triaxial actigraphy device. | The actigraphy device will be worn for approximately one week and, using data from days when the device was worn >10 hours, the average daily total activity counts determined. The secondary comparisons will be at 24 and 52 weeks after randomization. |
