This trial is testing whether a smartwatch (a HUAWEI Watch) can safely help doctors monitor patients after they've had a catheter-based procedure to replace a damaged aortic valve in their heart. The watch will continuously track your heart rate, oxygen levels, and heart rhythm, sending the information to your doctor so they can catch any problems early and let you go home sooner after surgery.
Right now, patients typically stay in the hospital for several days after valve replacement surgery so doctors can monitor their recovery. This study wants to see if a smartwatch can provide the same safety monitoring at home, which could let patients recover in their own environment while still keeping doctors informed.

You will receive a smartwatch before your valve replacement surgery and wear it starting at least one day before the procedure. After you go home, you'll need to take heart rhythm and oxygen readings at least twice daily for the first week, then twice weekly for the next month, then once weekly after that. The watch sends your data to a special app that your heart care team can see. You'll also have follow-up visits at your doctor's clinic at 1, 6, 12, 24, and 36 months after surgery to check your progress.
