The cost of rheumatic heart disease surgery varies depending on the type of surgery, the materials used, the function of the heart, the combination of underlying diseases, and the hospital in the region. A single valve replacement with a domestic valve costs about 70,000 yuan; an imported valve costs about 80,000 yuan; a double valve replacement with a domestic valve costs about 100,000 yuan; and an imported valve costs about 120,000 yuan. If there is a combination of atrial fibrillation at the same time, radiofrequency ablation is needed at the same time, and the cost may be around 140,000 yuan. If intraoperative left atrial thrombus removal, left atrial folding, and tricuspid valvuloplasty are performed at the same time, the cost may be higher. Combined with a major postoperative extracorporeal circulation complication, the cost may also increase a bit more.
