Surveillance Trial of the Apple Watch in Reliable Burden Assessment in Unseen Recurrence of Surgically Treated AF

Summary

This is a prospective multicenter clinical study comparing the efficacy of the Apple Watch AFib History tool to the iRhythm Zio Patch monitoring device in quantifying atrial fibrillation (AF) burden after surgical ablation. Patients with AF and mitral valve (MV) disease who undergo a Cox-Maze IV procedure concomitant to MV surgery will be evaluated at serial timepoints for up to 1 year postoperatively. The trial will be conducted in the United States at the Cleveland Clinic in Cleveland, OH and at the Washington University School of Medicine in St. Louis, MO.

* Use or access to Apple iPhone
* Willing and able to provide informed consent and wear both the Apple Watch and Zio Patch at pre-specified intervals for the duration of the study period
* Willing and able to participate in long-term follow up including study visits and surveys

Exclusion Criteria:

* Presence of a cardiac pacemaker
* Heart failure with reduced ejection fraction (\<40%)
* Concomitant aortic valve replacement or coronary artery bypass graft
