Pulmonary hypertension in congenital heart disease requires firstly control of pulmonary artery pressure, secondly medication and finally surgery. When pulmonary hypertension occurs in patients with congenital heart disease, symptoms such as dyspnea, angina and even fainting may occur, requiring long-term continuous treatment. 1. Control of pulmonary artery pressure includes maintaining normal oxygen saturation by administering oxygen, preventing infections, and avoiding low-oxygen environments. 2. Control and relieve pulmonary hypertension through medication, such as digoxin, warfarin and dobutamine. 3. Surgery is needed for patients with serious conditions. Early surgery is the most effective treatment for pulmonary arterial hypertension, and if the indications for surgery are met, surgery should be performed as much as possible. Medications should be used under the guidance of a doctor, and should not be used without authorization.
