Many people believe that the risk of catheter ablation of atrial fibrillation in the elderly is high, but this is due to a lack of understanding of the catheter ablation procedure. The so-called catheter ablation is actually a “minimally invasive” interventional procedure. It is performed under local anesthesia by puncturing a vein and providing a vascular access path, leaving only a skin incision the size of a needle eye. The catheter is fed into the heart to ablate the lesion causing atrial fibrillation. The procedure takes about 2 hours, and the puncture site only needs to be compressed with a sandbag for 6 hours after the procedure, which is well tolerated by the elderly. The incidence of atrial fibrillation is mainly concentrated in the elderly over 60 years of age, so atrial fibrillation in the elderly accounts for more than 80% of catheter ablation of atrial fibrillation in clinical work. From the practice of large electrophysiology centers at home and abroad, the safety of ablation is excellent, and the incidence of serious complications is actually less than 1%, indicating that catheter ablation can be safely and effectively performed in elderly people with atrial fibrillation.
