The study will recruit and follow up patients for five years patients newly diagnosed with congenital heart disease associated pulmonary arterial hypertension(CHD-PAH) from the investigator's hospital.

baseline include: An echocardiogram to assess the size, shape, pumping action and the extent of any damage to the heart. Lung function tests which include blowing measurements to assess gas volumes within the lungs as well as assessment of how the lungs exchange gases. Right heart catheterisation (RHC) to diagnose PAH Optional Cardiac Magnetic Resonance tests. 6 minute walk distance (6MWD). To measure exercise capacity Electrocardiogram (ECG), a test that measures the electrical activity of the heart Blood tests main outcome measure include: death heart/lung transplantation atrial septostomy hospitalization due to worsening of PAH start of new specific PAH treatment persistent decrease of \>15% from baseline in 6MWD (or \>30% compared with last study-related measurement) persistent worsening of World Health Organization (WHO) Functional Class (FC）
