In recent years, the incidence of atrial fibrillation (AF) is increasing year by year. Data show that the incidence of atrial fibrillation is as high as 10% or more among people over 60 years of age. Atrial fibrillation can lead to the heart can not work normally, the harm is serious. The hazards of atrial fibrillation are mainly in the following three aspects: 1, easy to form the left ear thrombus, thrombus dislodgement leads to stroke, heart and kidney and other important organs infarction. The incidence of stroke in patients with atrial fibrillation is 6-8 times higher than that in the normal population. 2.When atrial fibrillation attacks, the heart rate is too fast or too slow and serious arrhythmia, which can reduce the heart function by about 30%, and thus the mobility of the patient is also significantly reduced, and can even induce heart failure. 3.The sudden death rate of patients with atrial fibrillation is 2-4 times higher than those without atrial fibrillation. It is well known that patients with AF are prone to thrombosis and stroke, so it is important to not only treat AF, but also to prevent serious complications such as stroke, embolism, or heart failure, and to treat both the symptoms and the root cause of the problem. Numerous studies have shown that 90% of the blood clots in patients with AF are formed in the left atrium, so removing the left atrium can prevent blood clots from forming as well as avoiding the adverse effects of long-term anticoagulants. For patients with atrial fibrillation, the primary treatment goal is to convert them to normal sinus rhythm and remove the left auricle at the same time in order to eliminate the occurrence of thrombus and stroke. As a national key clinical specialty leader, I invented the May Minimally Invasive Atrial Fibrillation Procedure, which surgically treats atrial fibrillation completely and removes the left auricle at the same time. For atrial fibrillation caused by valvular disease or coronary artery disease, it is also possible to treat valvular disease or coronary artery disease and remove the left auricle at the same time as treating atrial fibrillation, which can also achieve good results. In clinical treatment, Mui’s minimally invasive atrial fibrillation treatment has the following five advantages: 1, the therapeutic effect of atrial fibrillation depends on whether the ablation line is precise, transmural, and intact, and the ablation lines used in Mui’s minimally invasive treatment are completed under endoscopy using ablation forceps, which completely ensures that the above requirements are met. 2.During the procedure, the left auricle, which is most prone to thrombus formation, is removed at the same time, which greatly reduces the risk of thrombus formation and embolism due to atrial fibrillation. 3.During the operation, the main factors affecting the onset of atrial fibrillation, such as the autonomic ganglia, can be removed from the epicardium. 4, only need to make two small holes of 1 to 2 centimeters in diameter on the left side of the chest and back can be completed, the operation is very traumatic, almost no scar. 5. The patient does not need to be exposed to X-rays during the operation, so the safety is high.
