GW25-e2288 Changes in the pulmonary artery pressure before and after transcatheter occlusion of congenital heart disease with left to right shunt: comparative evaluation using invasive and non-invasive approach

Conclusions The ultrasound estimation of pulmonary artery pressure is highly correlated with the measured value of cardiac catheterization , and therefore ultrasonic pulmonary arterial flow spectrum method can accurately estimate pulmonary artery pressure ;Transcatheter treatment of transcatheter closure of left to right shunt congenital heart disease could more effectively lowe pulmonary arterial pressure in patients with moderate to severe pulmonary hypertension.
