Radiofrequency ablation is not necessarily contraindicated in the elderly, it is just that they have a higher chance of post-procedure complications and should be more rigorously evaluated before the procedure. Cardiac radiofrequency ablation is a minimally invasive procedure that is mainly used to treat arrhythmias such as atrioventricular tachycardia, atrial flutter, and pre-excitation syndrome. Contraindications to cardiac radiofrequency ablation are uncontrolled local or systemic infection of the puncture, thrombosis of the cardiac chambers, and severe bleeding tendency. As the physiology and structure of the heart change in the elderly, and the recurrence rate and the chance of post-procedure complications are higher, it is necessary for the surgeon to carry out a more rigorous and comprehensive assessment of the patient’s condition to decide whether the patient is suitable for radiofrequency ablation. Complications of radiofrequency ablation mainly include peripheral vascular complications such as femoral arteriovenous fistula, pseudoaneurysm, peripheral arterial embolism, as well as catheter complications such as pericardial tamponade and myocardial perforation, and also venous thrombosis of the lower extremities, and in severe cases, pulmonary embolism. Therefore, whether elderly people can undergo radiofrequency ablation surgery needs to be decided after consulting with a specialized physician and balancing the pros and cons.
