After surgery, patients who undergo transcatheter aortic valve implantation (TAVI) are at risk of developing cardiac arrhythmias such as heart blocks and atrial fibrillation. Current practice is to monitor TAVI patients in hospital for 2-8 days post procedure using scarce and expensive hospital telemetry beds. This study will use a new monitoring service called mobile Cardiac Arrhythmia Diagnostics Service (m-CARDS) to risk stratify patient pre-TAVI and provide an added layer of monitoring that would support earlier discharge of suitably identified patients 24-hours post TAVI. The study will assess whether this strategy will significantly reduce the pressure on hospital resources while improving patient outcomes and experience.
