This anesthesia surgery is performed typically after the patient has already unsuccessfully attempted medical/pharmaceutical management of atrial fibrillation.<br><br>A bipolar radiofrequency ablator is inserted into the femoral vein. The femoral vein is utilized as a track to run the ablator to the chambers of the heart. Once there, access to the left atrium may be accessed through the foramen ovale

CARDIAC ABLATION – ATRIAL FIBRILLATION
Cancellation These cases may be cancelled if the TEE at the beginning of the procedure shows a thrombus in the atrium (these are usually found in the left atrial appendage).
Arterial Line standard for these cases to monitor for tamponade/hemodynamic instability. Hemodynamics can be very labile due to intermittent pacing and the general condition of the typical afib patient. Art lines can be difficult to place. If proving to be impossible, the anesthesia surgery may place an arterial line in the femoral artery. ACTs will be routinely taken via the arterial line.
Bite block A strong suggestion is to place a soft bite block after induction to protect against tongue/lip/tooth injuries during cardio versions.
Esophageal temperature monitor these are standard for these cases. Because the esophagus can be very close to where ablation will be taking place, the doctor is going to want to know if there are sudden changes in the esophageal temperature.
