Firstly, we will introduce the surgical treatments for pulmonary hypertension, one is interventional treatment. This is mostly seen in pulmonary hypertension associated with congenital heart disease, and then another is chronic thromboembolic pulmonary hypertension. Another interventional method is balloon atrial septal stoma, so the cost of these three cases is about 30,000 yuan for congenital heart disease, about 50,000 yuan for chronic thromboembolic pulmonary hypertension with stent implantation and balloon dilation, and about 30,000 yuan for simple balloon atrial septal stoma. Another surgical method is pulmonary artery thromboendarterectomy, which is indicated for chronic thromboembolic pulmonary hypertension, cardiac function is grade III or IV, the mean pulmonary artery pressure reaches 30 mmHg or more, and pulmonary vascular resistance is very high. The cost of this condition is relatively high and may be around $100,000. The other is lung transplantation, which can cost upwards of $300,000.
