We use radiofrequency ablation of atrial fibrillation: low X-ray, no contrast agent, no general anesthesia

Atrial fibrillation (AF) is one of the most common clinical arrhythmias. Now more and more patients want to use catheter ablation to cure atrial fibrillation. A brief explanation of the problem, I hope it can help.


First: Radiation problems during atrial fibrillation ablation surgery:


Because atrial fibrillation is a disease that involves the entire atrium and causes fibrosis and abnormal electrical activity, in the process of radiofrequency ablation, in order to be able to more clearly find the focus of treatment, radiological X-ray guidance is required for surgical treatment. In this way, X-rays may need to be repeated. Although the X-ray perspective in this range is not too harmful to the human body, it is still beneficial if the radioactive damage can be reduced as much as possible. Therefore, the treatment team has taken the lead in adopting the low-ray treatment mode in China since 2007, and the use of three-dimensional system navigation can greatly reduce the patient's X-ray exposure and also increase the success rate of surgery.


Second: Contrast agent problem:


Because the focus of atrial fibrillation surgery is due to the abnormal electrical activity of the left atrium and the connected large blood vessels at the junction site, it is necessary to determine the location of this junction site during the operation, and it is necessary to use a contrast agent to display under X-ray fluoroscopy. The contrast agent needs to be excreted from the kidneys, which naturally increases the burden on the kidneys. In the same way, our team also took this problem into consideration. Using 3D navigation can accurately locate this junction, and almost no contrast agent is needed during the operation.


Third: Anesthesia:


Due to the complexity of the atrial fibrillation surgery process, in order to ensure the smooth operation of the surgery, some centers need to allow patients to undergo general anesthesia before surgery. However, after years of research and taking into account the disadvantages of general anesthesia, our team innovatively proposed a method of performing atrial fibrillation aspiration and radiofrequency ablation under local anesthesia, which is relatively simple and economical. On the other hand, the surgical procedures are all performed under local anesthesia. No endotracheal intubation and mechanical ventilation are required, which not only reduces the damage of the endotracheal intubation to the patient, but also prevents the elderly patient from being able to leave the ventilator and transferring to the intensive care unit after surgery The necessity of using local anesthesia surgery has shortened the operation time significantly, and can be returned directly to the general ward after the operation to significantly reduce the burden on patients, which has obvious advantages.
