Signal Transfer of Atrial Fibrillation Data to Guide Human Treatment

Signal Transfer of Atrial Fibrillation Data to Guide Human Treatment

The purpose of the study is to gather electrophysiological data using a multi-electrode mapping catheter during a clinically indicated cardiac ablation procedure for the treatment of persistent atrial fibrillation.

Inclusion Criteria:

• Age 18 or above, or above legal age and willing and capable of giving informed consent specific to national law
• Scheduled for a clinically indicated cardiac ablation for the treatment of persistent atrial fibrillation
• Able to meet study requirements for follow-up visit

Exclusion Criteria:

• Permanent leads or presence of prosthetic or severely stenotic tricuspid or mitral valves
• Active systemic infection or sepsis
• Echocardiographically confirmed presence of thrombus
• Atrial thrombus, myxoma, inter-atrial baffle patch or occluder device for those subjects in whom a transseptal approach is required
• Subjects who cannot be anticoagulated or infused with heparinized saline
• Heparin induced thrombocytopenia
• Hemodynamic instability or shock
• Atrial anatomy contradictory to catheter labeling or size indices
• EF < 35%
• Subjects with an active heart failure decompensation
