Wearable Smartwatch Facilitated Remote Health Management for Patients Undergoing Transcatheter Aortic Valve Replacement

Abstract

Background In the recent decades, the development of novel digital health technologies enables doctors to monitor ECG and vital signs remotely. But the data on applying the noninvasive wearable smartwatch on patients with transcatheter aortic valve replacement (TAVR) are unknown. Methods and Results We performed a prospective, observational cohort study to evaluate the feasibility of a novel, virtual, and remote health care strategy for patients with TAVR discharged to home with smart wearable devices. A total of 100 consecutive patients with severe aortic stenosis who underwent elective transfemoral TAVR were enrolled and received the Huawei smartwatch at least 1 day before TAVR. Vital signs, including heart rate, rhythm, oxygen saturation, and activity, were continuously recorded. Single‐lead ECG was recorded twice per day in the week following TAVR discharge and at least 2 days a week for the subsequent month after TAVR discharge. A designated heart team member provided remote health care with the data from the smartwatch when the patient had a need. Thirty‐eight cardiac events were reported in 34 patients after discharge, with most of the events (76.0%) detected and confirmed by the smartwatch. Six patients were advised and readmitted to the hospital for arrhythmia events detected by the smartwatch, of whom 4 patients received pacemaker implantation. The remaining 28 (82.4%) patients received telemedicine monitoring instead of face‐to‐face clinical visits, and 3 of them received new medication treatment under the online guidance of doctors. New‐onset left branch bundle block was found in 48 patients, with transient characteristics, and recovered spontaneously in 30 patients, and new‐onset atrial fibrillation was detected in 4 patients. There were no significant differences in the average weekly heart rates or the ratio of abnormal or low oxygen saturation when compared with the baseline. The average daily steps increased over time significantly (baseline, 870±1353 steps; first week, 1986±2406 steps; second week, 2707±2716 steps; third week, 3059±3036 steps; fourth week, 3678±3485 steps, P <0.001). Conclusions Smartwatches can facilitate remote health care for patients discharged to home after undergoing TAVR and enable a novel remote follow‐up strategy. The majority of cardiac clinical events that occurred within 30‐day follow‐up were detected by the smartwatch, mainly because of the record of conduction abnormality.

Ambulatory Smartwatch ECG Monitoring among Patients Undergoing Transcatheter Aortic Valve Replacement Early after Discharge: An Observational Study

“…[36]. Smartwatches with similar functions of single-lead ECG collection have also been reported in other brands, such as Apple Watch and Huawei Smartwatch [10,23]. The telecare function of smartwatch might be especially demanded during the COVID-19 pandemic nowadays to overcome the difficulty in achieving in-site outpatient assessment.…”

Daily Physical Activity Measured by Wearable Smartwatch for Patients Undergoing Transcatheter Aortic Valve Replacement: Insights From the SMART TAVR Study

“…Our previously published data showed that the step count in patients after TAVR progressively increased within 1 month. 9 In this study, we have identified the median step of 3069 (IQR, 1830-5028) among 222 patients within the first month after TAVR. It was consistent with previous pilot studies monitoring PA in 10 patients after TAVR using wearable activity trackers, such as the Fitbit-Flex (Fitbit, Inc, San Francisco, CA).…”

“…Detailed information for the cohort has been published elsewhere. 9 Briefly, the registry started in July 2020 and consecutively recruited patients undergoing elective transfemoral TAVR. Participants were provided with a smartwatch (Huawei Watch GT 2 Pro ECG edition) to record their health information including daily activity, heart rate, pulse oxygen saturation, and single-lead ECG.…”

Telemedical management in patients waiting for transcatheter aortic valve implantation: the ResKriVer-TAVI study design

“…Few studies investigated TIM in AS patients undergoing TAVI. The studies focused mainly on the detection of conduction disturbances after TAVI and the need for pacemaker implantation ( 19 , 20 ). In the prospective cohort study Redirect TAVI, continuous pocket electrocardiograms were used to detect conduction disturbances in 192 AS patients without pacemakers 14 days before and after TAVI ( 19 ).…”
