Interest of a Hybrid Connected Watch for Cardiac Rhythm Monitoring in Post-operative Cardiac Surgery

The objective of this single-center pilot study is, with the help of a connected watch, to show the absence of recurrence or maintenance of sinus rhythm in patients with a Post Operative Atrial Fibrillation (POAF) and to help treating cardiologists in the care of these patients.

Inclusion Criteria:Major with an indication for conventional cardiac surgery with de novo postoperative AF onset.Agreeing to participate in the study and having signed an informed consent.Agreeing to undergo 12 months of postoperative monitoring.Exclusion Criteria:Patient with pre-operative AFPatient who does not have a smartphone compatible with the connected watch.Patient unable to perform an ECG measurement independently.Patient with a physical constraint to the measurement (arteriovenous fistula...)MinorsPregnant or breast-feeding womenAdults under guardianship, under curatorshipPatients whose life expectancy is less than 1 yearPatients participating in another therapeutic trial likely to impact the evaluation criteria of the MONHYCARD studyContraindication to long-term anticoagulantsPatients implanted with a mechanical valve prosthesis pre-operatively or after surgery
