Official Title
SMART TAVR: SMART Watch Facilitated Early Discharge in Patients Undergoing Transcatheter Aortic Valve Replacement
Brief Summary
The purpose of this study is to observe conduction disturbance, daily activity level, heart rates, oxygen saturation in patients who underwent Transcatheter Aortic Valve Replacement (TAVR) and to evaluate the utility of the HUAWEI Watch (HUAWEI Technologies Co., Ltd., Shenzhen, China) for the potential early warning sign of changes in multiple biometric parameters including heart rate, rhythm, oxygen saturation, activity, and sleep in patients following TAVR. This will be evaluated in the context of a recently implemented early discharge protocol.
Detailed Description
This is a prospective observational cohort study including patients undergoing TAVR procedure in Second Affiliated Hospital of Zhejiang University, School of Medicine. HUAWEI Watch will be assigned to patients within 24 hours before TAVR. HUAWEI Watch GT series can continuously monitor and record multiple biometric parameters heart rate, step counts, sleep cycles and can detect and record the pulse oxygen saturation, as well as analyze QRS complexes and P waves after triggering. The patients will be followed in outpatient clinic visits at 1, 6, 12, 24, and 36 months after TAVR and will commence monitoring with the HUAWEI Watch protocol at least 1 day before the scheduled TAVR procedure to allow familiarity with the device. Patients will be required to activate SMART watch readings (including pulse oxygen saturation and ECG) at least once prior to TAVR and twice per day in the week following TAVR discharge (morning and late afternoon/early evening), at least two days a week for the subsequent month after TAVR discharge and at least once weekly for the remainder of the study. Patients will also be required to activate SMART watch readings at times of any cardiovascular symptoms including dyspnea, chest pain, palpitations, dizziness or presyncope. The health data recorded by HUAWEI Watch will be transmitted to HUAWEI phone application. The Heart Health App (developed by Second Affiliated Hospital, School of Medicine, Zhejiang University) will receive, process and store the data, and transfer it to remote database after approval by patients. A designated heart team member would access the data via a cloud database, contact the patient further investigation or management was deemed necessary.
