Left auricular occlusion is a minimally invasive interventional procedure for the treatment of atrial fibrillation, which seals the left auricle where blood clots are generated. After the procedure, patients with atrial fibrillation do not need to take oral anticoagulant medication for a long period of time, and it also reduces the number of thromboembolic events caused by atrial fibrillation. However, the price of left auricular occlusion is not cheap, and the cost varies according to the hospitals in each region, but it is around 70,000 to 80,000 yuan, and may reach 100,000 yuan in some regions due to the different materials used. The reimbursement policy varies from region to region and the scope of reimbursement also varies. However, since patients with atrial fibrillation need to take long-term oral anticoagulant drugs, and the cost of anticoagulant drugs for a year is also relatively expensive, compared with the higher success rate of left ear blockade, patients with atrial fibrillation can be performed at the same time atrial fibrillation radiofrequency ablation and left ear blockade surgery, to improve the quality of life, compared with the long-term oral anticoagulant drugs, the cost is still appropriate.
