Methords Through the right subclavian vein or jugular vein, floating catheter is inserted into pulmonary artery and monitor hemodynamics of right heart. Hemodynamics and acute pulmonary vasoreactivity testing are used to guide treatment of the patients with CHD. Results There were 85 cases with bidirectional shunt and severe PH. There were floating catheter retention of 4 to 13 days (average 7.5 days). Mean systolic pulmonary artery pressure(PAP) / mean systolic body artery blood pressure (BP) and mPAP / mBP were equal to 1.22 ± 0.35 and 1.07±0.11 respectively. The patients presented total pulmonary vascular resistance of 17.6±4.3 Wood units. Acute pulmonary vasoreactivity testing was positive in 67 cases. 14 cases with Eisenmengers syndrome underwent medical treatment. 71 cases underwent surgical treatment. With compared to preope
