Key result
Post-TAVR digital health tools show early functional promise but lack hard clinical endpoint evidence.
Why the study?
Digital health interventions have been increasingly applied in cardiac surgery, but evidence specifically for TAVR home self-management remains fragmented and implementation barriers are not well mapped.
What are the application forms, functions, outcomes, and implementation barriers of digital health interventions in home self-management for patients undergoing transcatheter aortic valve replacement?
What are the application forms, functions, outcomes, and implementation barriers of digital health interventions in home self-management for patients undergoing transcatheter aortic valve replacement?
Digital health interventions offer promising support for post-TAVR home management by improving functional outcomes and reducing readmissions, though overcoming the digital divide and device connectivity barriers is essential for widespread implementation.
AIM: To systematically map the application forms, functions, outcomes, and implementation barriers of digital health interventions (DHIs) in home self-management for patients undergoing transcatheter aortic valve replacement (TAVR). DESIGN: Scoping review following the Joanna Briggs Institute methodology with a published a priori protocol. DATA SOURCES: A systematic search was conducted in PubMed, Cochrane Library, Embase, Web of Science, CINAHL, CNKI and Wanfang Databases from inception to 26 August 2026. METHODS: This scoping review was conducted in accordance with the Joanna Briggs Institute (JBI) methodology and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). A protocol was prospectively registered on the Open Science Framework. RESULTS: 19 studies were included. DHIs for post-TAVR home self-management covered seven application forms: wearable devices, mobile applications, remote monitoring platforms, AI-powered voice virtual assistants, remote video training platforms, social media platforms and integrated management platforms. Their core functions included remote ECG monitoring, home-based exercise rehabilitation, multi-parameter physiological monitoring, health education and AI-driven follow-up. Current evidence suggests potential positive effects of DHIs on improving exercise capacity, reducing readmission rates, enhancing intervention adherence and increasing patient satisfaction. CONCLUSION: DHIs for post-TAVR home self-management feature diverse forms and integrated functions, with preliminary evidence suggesting positive effects on multiple outcomes. However, evidence for hard clinical endpoints remains limited, and dedicated health economic evaluations are largely absent. The digital divide remains a key barrier to clinical implementation. Future efforts should optimize technology combinations, improve age-friendly design, promote stratified care and advance reimbursement policies. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: DHIs offer promising support for post-TAVR home management. Addressing accessibility and usability barriers is essential to translate these benefits into routine care. Nurses play a pivotal role in patient education, digital literacy support and remote monitoring coordination. IMPACT: What is already known? ○ Digital health interventions have been increasingly applied in cardiac surgery, but evidence specifically for TAVR home self-management remains fragmented. What this paper adds? ○ This scoping review systematically maps the application forms, functional modules, outcomes, and implementation barriers of DHIs in post-TAVR home self-management, identifying evidence gaps and highlighting the digital divide as a key implementation challenge. IMPLICATIONS FOR PRACTICE: Nurses and healthcare providers can leverage DHIs to support post-TAVR patient education, remote monitoring and rehabilitation, but must consider patients' digital literacy and accessibility needs when implementing these technologies. NO PATIENT OR PUBLIC CONTRIBUTION: This is a scoping review study. TRIAL REGISTRATION: Open Science Framework (OSF): https://osf.io/kuz7b/overview.

Chen et al. (2026) conducted a review in Post-transcatheter aortic valve replacement (TAVR). Digital health interventions (DHIs) vs. Usual care or non-users (in included studies) was evaluated on Application forms, functions, outcomes, and implementation barriers of DHIs in post-TAVR home self-management. Digital health interventions for post-TAVR home self-management encompass diverse forms with preliminary evidence of positive functional outcomes, but widespread implementation is hindered by the digital divide and a lack of hard clinical endpoint evidence.
