  Background: In patients with atrial septal defect (ASD) and severe pulmonary arterial hypertension (PAH), diastolic pulmonary arterial pressure (DPAP) correlates closely with pulmonary vascular resistance (PVR) and can reflect the severity of pulmonary vascular disease. However, it is unclear whether DPAP has potential to become a prognostic indicator for closure of ASD with severe PAH. Objectives: This study was performed to investigate the prognostic implication of DPAP in patients with ASD and severe PAH. Methods: Among 232 patients with ASD and severe PAH (systolic pulmonary arterial pressure (SPAP)≥70 mm Hg measured with right heart catheterization), 85 patients (21M/64F) undergoing closure of ASD were followed up. Doppler-calculated SPAP was recorded to identify the normalized post-operative PAP (SPAP<40 mm Hg). According to the cut-off value of DPAP from a ROC curve, two .. Read More»
