Which is worse, surgical ablation or medical catheter ablation? This question is very intuitive, we answer from the following aspects: 1 look at the history, medical catheter ablation has more than 20 years of clinical application, surgery is only about 5 years; 2 look at the number: catheter ablation currently large domestic centers more than a thousand cases / year, more than 100 cases of hospitals abound, while surgery more than 100 cases / year almost no; 3 look at the mechanism: about 90% of the lesions of atrial fibrillation originated in the pulmonary veins, about 10 If the lesion originates from other parts, surgery can do nothing; 4 look at the trauma: internal medicine does not have any incision; 5 look at the patient: internal medicine ablation can be applied to all patients, surgery is only applicable to patients with paroxysmal atrial fibrillation; 6 look at the recovery: internal medicine ablation can live normally the next day; 7 look at the recurrence, internal medicine ablation can be repeated; 8 look at the process, internal medicine is only one hour.
