  • Current or planned participation in an investigational or observational drug or device trial related to the treatment of atrial arrhythmias

Interventions

PROCEDURESurgical Ablation

In addition to the concomitant surgery, subjects are required to have amputation or closure (with sutures or ligation) of the left atrial appendage.The Cox Maze IV lesion set is required to be performed.

DEVICECardioblate and Cryoflex hand held devices

The Cardioblate hand held devices consist of the Cardioblate iRF and Cryo surgical ablation devices.
