Foresight Intracardiac Echocardiography System (ICE)

Visualization of Human Cardiovascular Anatomy With Foresight Intracardiac Echocardiography (ICE) System

This study will evaluate the efficacy of the Foresight Intracardiac Echocardiography system ,with improved image quality, in guiding trans-septal punctures during atrial fibrillation ablation procedures.

The study will recruit 10 patients at a single center.

Inclusion Criteria:

• Patient is at least 18 years old.
• Patient is undergoing an atrial fibrillation ablation procedure.
• Patient has a transesophageal echocardiogram (TEE) within the 48 hours prior to ablation procedure to rule out left atrial thrombus.
• Patient provides informed, written consent for participation in the study.

Exclusion Criteria:

• Patients in whom placement of an ICE catheter in the right atrium for adequate atrial visualization is not technically feasible (as evaluated and determined by the physician/study investigator performing the procedure).
• Patients in whom transseptal puncture is relatively contraindicated.
• Patients in whom left atrial clot or dense spontaneous contrast is identified on TEE, which would increase thromboembolic risk.
• Women of child bearing potential, in whom pregnancy cannot be excluded.
• Patients unable to grant informed, written consent for participation in the study.
