Atrial fibrillation (AF) is the most common persistent arrhythmia in humans. There are at least 8 million atrial fibrillation patients in China, and the number of patients will continue to increase with the aging of the population. the incidence of atrial fibrillation in people over 65 years old is 3-5%, and the incidence of atrial fibrillation in people over 80 years old is 9%. Atrial fibrillation can cause palpitations, chest tightness, fatigue and other discomforts, and in severe cases, it can cause ischemic stroke, heart failure and even death. Currently, atrial fibrillation is treated with medication, catheter-based interventional ablation therapy and surgery. Drug therapy is commonly used, but the efficacy is poor, as the interventional ablation therapy and surgical treatment of cardiac rhythm maintenance auxiliary method is more effective. Surgical radiofrequency ablation features: 1, good efficacy: the current surgical treatment of atrial fibrillation is the best efficacy, can reach more than 90%, the technical operation is more intuitive than the internal catheter ablation, simple and effective; 2, high accuracy: surgical ablation of atrial fibrillation is carried out under the condition of the operator to see the ablation treatment, the ablation of the line is clear, accurate, can effectively avoid many complications; 3, fewer complications: left atrial thrombus originates from 90% of the left atrium. 90% of thrombus originates from the left atrium (the part of the left atrium that protrudes from the front to the right is called the left atrium). Surgical treatment also removes the left atrium, eliminating thrombus formation due to atrial fibrillation and avoiding the occurrence of cerebral thrombosis to a large extent, while medical catheter ablation is unable to remove the left auricle; 4. No radiation: Surgical radiofrequency ablation patients do not need to go through the prolonged exposure to X-rays in medical catheter ablation, and there is absolutely no risk of radioactive damage. There is no risk of radioactive damage; 5, safe and rapid: because the surgical operation on the need for radiofrequency ablation of the region shows very clearly, so it can quickly complete the radiofrequency operation, the operation time of 10-15 minutes, far shorter than the time of the medical catheter ablation; 6, low cost: the cost of a domestic catheter ablation of about 70,000 yuan, while the surgical ablation treatment cost is low, about 40,000 yuan. However, its defects are also very obvious: the surgery is more traumatic, and the pain of the surgical incision is often the main reason for the patient’s concern. The current surgical treatment has three main categories: 1, the classic maze surgery (Maze surgery): Maze surgery is to cause a pathway that enables the impulse from the sinus node to reach the AV node in order to drive the ventricle, the surgery avoids atrial folding, preserves atrial synchronization and postoperative atrial transmission function, and at the same time eliminates the risk of thrombosis. The efficacy of labyrinthine surgery is very good, and it has been reported in the literature that sinus rhythm is maintained up to 98%, and the protection of right atrial function reaches 99%, and the protection of left atrial function reaches 93%. 2, radiofrequency ablation technology: radiofrequency ablation is the use of high temperature to produce myocardial tissue coagulation, the formation of scar, to eliminate the abnormal electrical conduction. With the improvement of technology, bipolar radiofrequency pen began to be used in clinical application. Bipolar radiofrequency pen ablation produces less damage to the surrounding tissue and better maintains atrial transmission function. It has been reported in the literature that bipolar radiofrequency ablation line of patients with simultaneous mitral valve surgery and coronary artery bypass grafting atrial fibrillation, follow-up for 6 months, 93.1% of the patients to maintain sinus rhythm. 3, surgical small incision atrial fibrillation ablation surgery: representative of the first technology for thoracoscopy-assisted WolfMini-maze surgery. With the progress of minimally invasive ablation technology, the application of advanced ablation equipment while using thoracoscopy or small incision, can be in the beating state of the heart for epicardial ablation, the advantages of its patients with little damage, fast and accurate operation, fewer complications, and good efficacy. Minimally invasive surgery avoids the traditional chest opening in the middle of the heart, which is less damaging, safer, does not require extracorporeal circulation, and has a clear and accurate ablation line; at the same time, it also avoids the radioactive damage caused by prolonged exposure to X-rays required for catheterized ablation in the internal medicine department Dr. Wolf reported that the cure rate of atrial fibrillation at 6 months could reach 91.3%, and it also exempts from taking antiarrhythmic drugs and anticoagulant medications. The overall cure rate at 2 years after surgery was 80%. The indications for surgical treatment of atrial fibrillation include: 1, patients with obvious symptoms of atrial fibrillation, such as heart valve disease, coronary artery disease, etc.; 2, patients who are ineffective in the treatment of antiarrhythmic drugs, or who are unable to tolerate the drug treatment; 3, patients with recurrence of atrial fibrillation after ablation; 4, patients who are unable to undergo catheterization due to the presence of thrombus in the left auricle, or patients who are highly suspected of having a thrombus. 5, patients who have combined with antiarrhythmic drugs, coronary artery disease or heart valve disease, Patients with atrial fibrillation who are also combined with valve disease and coronary artery disease.
