Atrial fibrillation is a disorganized rhythm originating in the upper chambers of the heart that can contribute to palpitations (fast heart rates), worsening of heart failure or stroke. While medical therapy offers some relief, therapy fails many patients eventually or they cannot tolerate it because of side effects. Recent advances have allowed physicians to perform ablations to eliminate atrial fibrillation.

Atrial fibrillation ablation is a specialized technique that requires expertise, specialized technology, careful patient selection and close follow-up.

Prior to the procedure, the physicians utilize the Department of Cardiology’s specialized cardiac MR (magnetic resonance) scanner to visualize the left atrium and pulmonary veins. This is where much of this rhythm disturbance originates. The physician uses these images to more precisely plan and guide the placement of catheters and ablation lesions during the procedure. In addition, an intra-cardiac echo provides real-time visualization of the ablation procedure to maximize safety.

Both Dr. Chun and Dr. Narayan are present during the entire procedure, along with a team of experienced nurses and technicians who provide detailed care during all aspects of the procedure. The procedure is performed under general anesthesia to maximize the patient’s comfort. Patients can expect to spend one night in the hospital after the procedure. Most patients resume their normal activities within a few days. The physicians use extensive outpatient event monitoring before and after the procedure to document all symptomatic episodes and as a surveillance measure to document possible asymptomatic episodes.

An in-depth consultation can be arranged to see if ablation therapy is suitable for you.
