Using the HUAWEI Smart Watch to Support Early Discharge After Transcatheter Aortic Valve Replacement in Adults with Severe Aortic Stenosis

What this Trial Is About

Researchers are observing patients who have undergone Transcatheter Aortic Valve Replacement TAVR to study conduction disturbances, daily activity levels, heart rates, and oxygen saturation. The study aims to evaluate how well the HUAWEI Watch can provide early warnings of changes in heart rate, rhythm, oxygen levels, activity, and sleep patterns after TAVR, especially in the setting of a new early discharge protocol. Patients will receive a HUAWEI Watch within 24 hours before their TAVR procedure. This device continuously tracks heart rate, step counts, sleep cycles, oxygen saturation, and certain heart rhythm features like QRS complexes and P waves. After TAVR, patients will follow a schedule of outpatient visits at 1, 6, 12, 24, and 36 months. They will use the watch to record biometric readings at least twice daily for the week after discharge, a few times weekly during the following month, and at least weekly thereafter. They also record readings during any cardiovascular symptoms. The collected health data is transmitted to a phone app and then securely stored and reviewed by a heart team member. The team monitors for concerning changes that may require further action. The study measures include death and rehospitalization rates, days alive and out of hospital within 30 days, and long-term follow-up of heart function, arrhythmias, physical activity, oxygen levels, and cardiac events over three years.
