Catheter ablation surgery involves scarring the affected cardiac tissue using radio waves generated from electrode-fitted catheter, notes Healthline. This hinders the passage of electrical impulses through the tissue, hence restoring a normal heartbeat. Though useful, catheter ablation surgery may cause bleeding and bruising.

MAZE surgery is appropriate when a patient is undergoing another surgical procedure for another heart condition, explains Healthline. It involves cutting and sewing together various incisions in the heart to create a scar, which hinders the passage of the impulses. This procedure is risky as it may result in stroke and failure of important organs, such as the kidney.
