Effectiveness of Remote Cardiac Rehab After Surgery for Acquired Heart Valve Disease

The goal of this clinical trial is to learn if home-based cardiac rehabilitation using remote monitoring devices improves exercise capacity in patients after surgery for acquired heart valve diseases. It also aims to learn about factors affecting the outcomes of remote treatment. The main questions it seeks to answer are: * How does cardiac rehabilitation using remote monitoring devices improve exercise capacity in participants compared to those undergoing rehabilitation at medical facilities? * What factors influence the outcomes of participants undergoing cardiac rehabilitation with remote monitoring devices? The researchers compare the exercise capacity of the intervention group - receiving home-based cardiac rehabilitation using remote monitoring devices - with that of the control group receiving treatment at a rehabilitation facility during the recovery phase. All patients participating in the study receive inpatient cardiac rehabilitation during the acute phase (1 week) and the early recovery phase (1 week) at the hospital. The control group continues supervised outpatient rehabilitation at the hospital, three sessions per week for the following month. The intervention group undergoes home-based rehabilitation under the guidance of a therapist via the Open TeleRehab platform and self-monitors hemodynamic parameters using a personal blood pressure monitor and a handheld pulse oximeter. Both groups are assessed for exercise capacity at baseline (pre-surgery), after each phase of rehabilitation, and one month after hospital discharge.
