Catheter Ablation (Radiofrequency/Cryoballoon)

Catheter ablation can be considered when atrial fibrillation recurs and causes symptoms, or when drug control is insufficient or not tolerated. The decision is based on the type of atrial fibrillation (paroxysmal/persistent), left atrial structure and comorbidities, previous drug or electrical cardioversion responses, and the availability of appropriate equipment and perioperative anticoagulation conditions. The final decision is made by a cardiac electrophysiology specialist through comprehensive evaluation.
