Device: Foresight ICE System The Foresight ICE System is composed of a sterile, single-use catheter intended to operate with a Foresight ICE PIM and Hummingbird console. The Foresight ICE system will be used in guiding the physician during the trans-septal puncture and provide physiological information during the course of the procedure.

Wide visualization of the the heart anatomy and additional devices used during atrial fibrillation ablation procedures.

The ability of the study device to identify the atrial septum during transseptal puncture will be evaluated by the physician on the day of the procedure and captured in the individual case report form. This will be based on the objective finding of whether the transseptal puncture was performed (Yes or No) under study device guidance. This information will be gathered for each patient in the individual case report form and presented qualitatively and as quantitative measures (percentage success).

The Conavi's Foresight System will be utilized to capture images of relevant human cardiac anatomical landmarks (e.g. crista terminalis, tricuspid valve, coronary sinus) while the catheter will be manipulated inside the heart during the procedure. The physician satisfaction survey will ask the physician to specifically tabulate structures that could be identified in a binary yes/no format.

This kind of information will be gathered for each patient in the individual physician satisfaction surveys and presented qualitatively.
