SMART Watch Facilitated Early Discharge in Patients Undergoing Transcatheter Aortic Valve Replacement

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.
