Left ear occlusion is a minimally invasive interventional procedure for the treatment of atrial fibrillation that seals the site of thrombus production in the left heart ear. After the procedure, patients with atrial fibrillation do not need to take long-term oral anticoagulant drugs, and it also reduces the number of thromboembolic events caused by atrial fibrillation. However, the price of left ear blocking is not cheap and varies according to the hospitals in each region, but it is around 70,000-80,000 RMB, and in some regions it may reach 100,000 RMB due to the different materials used. Reimbursement policies vary from region to region, and the scope of reimbursement varies. However, because patients with atrial fibrillation need to take long-term oral anticoagulant drugs, and the cost of anticoagulant drugs is relatively expensive for one year, compared to the higher success rate of left-ear occlusion, patients with atrial fibrillation can undergo both radiofrequency ablation of atrial fibrillation and left-ear occlusion surgery to improve their quality of life, and the cost is still appropriate compared to long-term oral anticoagulant drugs.
