Remote Acute Monitoring-based Same-day Discharge Strategy of Post Transcatheter Aortic Valve Implantation Patients Versus Standard Care at 30-Day Follow-up

Given the susceptibility of post-TAVI patients to bradyarrhythmias and extended hospitalisation is not economically plausible, a shift toward remote monitoring could be both justifiable and has the potential to enhance outcomes and able to predict deterioration following TAVI. Despite the well-characterized high safety and effectiveness profile of TAVI across various surgical risk groups, the adoption of same-day discharge remains limited. Addressing post-TAVI arrhythmias is crucial to minimising the total postprocedural length of stay. Therefore, by embracing a minimalist approach and leveraging the vastly grown operators experience, the current post-TAVI care could be further enhanced with the integration of remote monitoring. This strategic shift aligns with the objective of optimising care by the ability to predict deterioration that can be treated to avoid in-hospital care.

Technology-enabled patient care and monitoring has been steadily improving, and AI-enabled remote patient monitoring devices has brought a crucial advantage to an outside-of-hospital cardiac investigation. The potential to remotely detect any adverse effects that patients might develop after the procedure is promising. There is an increased uptake of ECG telemetry, which might serve as a valuable tool that may significantly reduce hospital LOS at 30 days and possibly could reduce 3 months' adverse outcomes. This approach may enhance patient care and optimise post-TAVI outcomes through an efficient patient-tailored approach. Several studies have utilised remote or ambulatory ECG for post-TAVI on different clinical outcomes - however, to date, no RCT has been conducted using this approach. The findings of remote ECG monitoring studies are inconsistent with various monitoring periods and patient selection criteria. Although such studies utilised ECG monitoring, they did not integrate a strategy or pathway for out-of-hospital monitoring and clinical decision algorithms during home monitoring. To date, the TELE-TAVI trial will be the first monitoring study to incorporate live event detection and alert notification system supported by the bespoke Smartcardia 7-lead continuous ECG patch monitor in an RCT.

In order to better understand the impact of remote patient monitoring after TAVI, this trial proposes the utilisation of a remote monitoring algorithm to provide essential clinical data for guiding management, with the primary aim of reducing postprocedural hospital length of stay and readmissions. This strategic technology integration aims to address the gaps identified in previous studies and enhance the effectiveness of post-TAVI patient care.

Thus, it has been hypothesised that:

1. A remote patient monitoring protocol-driven strategy for same-day discharge, post-TAVI, is superior to the current standard of care follow-up in reducing cumulative 30-day hospital length of stay (LOS).
2. The novel remote patient monitoring strategy, supported by a clinical decisions algorithm, is more effective at prioritising patient presentations and optimising outcomes through early identification of adverse events, such as the need for a pacemaker, when compared to the standard of care.
