Abstract：Objective To compare the changes of pulmonary artery pressure[systolic pulmonary pressure (PASP)and mean pulmo-nary pressure(PAMP)]before and after transcatheter occlusion in patients with ventricular septal defect (VSD).Methods Six hun-dred and fifty patients with VSD underwent transcatheter closure were involved in this study.The parameters of pulmonary artery pressure including PASP and PAMP were evaluated with cardiac catheter before and after procedures.transthoracic echocardio-graphy examination performed at 3 days after procedures and during fol ow up of next six months.Results There was significantly relationship between the pulmonary arterial pressure measured by Doppler echocardiography examination and cardiac catheter ex-amination before transcatheter occlusion in patients with VSD.In normal group,PASP had not significant changes.PAMP increased at 3 months from the operation.In mild pulmonary hypertension group,PASP and PAMP increased immediately after operation,which decreased apparently at 6 months(P<0.05).In moderate pulmonary hypertension group,PASP and PAMP decreased apparently immediately after the operation(P<0.05).The pulmonary pressure was decreased during the fol owing 6 months(P<0.05).Con-clusion Transcatheter closure of VSD with mild or moderate pulmonary hypertension is safe and effective.
