Heart ablation surgery, specifically catheter ablation for atrial fibrillation (AF), is generally considered a serious but routine procedure with some risks. The overall risk of any complication ranges from about 4% to 6%, while the risk of major or serious complications is approximately 1% to 2%. Major complications include stroke (0.5% to 1%), cardiac tamponade (damage to the heart wall requiring urgent care), pulmonary vein stenosis, infections, blood clots, and rare but serious damage to the esophagus or nerves. The risk of death from the procedure is very low, around 1 in 1000. Most complications are infrequent, and cardiac ablation is often recommended when the benefits outweigh these risks, especially for those with significant symptoms or persistent arrhythmias. Recovery typically involves a short hospital stay and mild discomfort, with follow-up monitoring to ensure success and manage any recurring symptoms.
