If it is a successful ablation procedure and there are no serious complications, there are no sequelae, but there may be sequelae in the following cases: 1. Intraoperative complications, ablation treatment damages the patient’s normal conduction system, such as damage to the atrioventricular node and the bundle of Hitchcock, if it causes irreversible third degree conduction block, the patient needs to implant a pacemaker for treatment; 2. The grasp of ablation energy during radiofrequency ablation is not too If the ablation energy is too large, it will cause myocardial damage, resulting in pericardial tamponade, which will require surgical open-heart treatment in serious cases; 3, if the ablation catheter operation damages the patient’s heart valves, resulting in serious incomplete closure or stenosis, which will require surgical valve replacement in serious cases; 4, other complications, such as local hematoma or bruising at the puncture site after ablation, which will gradually recover with time. These complications will gradually recover over time and will not leave sequelae. If radiofrequency ablation treatment is successful without complications, there will be no sequelae, but only when there are serious complications will there be complications. If treated in a timely and appropriate manner, it will not leave lifelong complications and will gradually recover without affecting the patient’s normal life and normal heart function.
