Effects on pulmonary arterial systolic pressure after surgical closure of ventricular septal defect
Background: Pulmonary arterial hypertension (PAH) is a common complication of ventricular septal defect (VSD) caused by chronic left-to-right shunting and increased pulmonary blood flow. This study evaluated the effect of surgical VSD closure on pulmonary arterial systolic pressure (PASP) in patients with varying degre...
