How many hours does a radiofrequency ablation of atrial fibrillation usually take?

Atrial fibrillation radiofrequency ablation procedure time is related to the severity of the disease and the skillfulness of the doctor, and it takes from 1 to 4 hours.
Atrial fibrillation radiofrequency ablation surgery is performed by peripheral vascular puncture, moving the electrodes into the atria, destroying the lesion area through radiofrequency currents at the contact area between the local catheter and the heart, and effectively eliminating the diseased tissues that induced atrial fibrillation.
The radiofrequency ablation procedure for atrial fibrillation requires experienced physicians to carefully search for each ectopic pacing site and interrupt each abnormal pacing site in order to completely eliminate atrial fibrillation. Therefore, the procedure is relatively complex.
Experienced doctors, who are skillful in the operation, use a relatively shorter time. In general, the procedure takes about 3-4 hours for patients with severe disease, and about 1-2 hours for patients with relatively mild atrial fibrillation and experienced doctors.
There are different degrees of damage to the heart muscle during RF treatment, and it takes about 2-3 months for this damage to be slowly replaced by scar tissue. Therefore, after radiofrequency ablation of atrial fibrillation, it is recommended that the patient be discharged from the hospital and maintained on oral amiodarone 200 mg/d for 6 months, while the patient takes aspirin l00 mg/d and clopidogrel 75 mg/d for 6 months after the procedure.
