Whether atrial fibrillation surgery is a major surgery needs to be judged according to the surgical method, the common maze surgery belongs to major surgery, radiofrequency ablation treatment belongs to minimally invasive surgery. 1. Maze surgery: Atrial fibrillation surgery can be treated by maze surgery, which can restore sinus rhythm, mainly through a series of incisions to interrupt the more common refractory loops, to rebuild the special conduction pathway, so that the atrial electrical activity to play the effect of synchronization to eliminate atrial fibrillation. 2. Radiofrequency ablation therapy: radiofrequency current is introduced into the heart through a catheter to create tiny scars in designated areas of the heart muscle, eliminating unstable signals in the heart and restoring normal rhythm. Patients are advised to actively cooperate with the treatment under the guidance of their doctors and according to their specific conditions.
