Outcomes in patients with pulmonary hypertension undergoing percutaneous atrial septal defect closure

Abstract

Transcatheter closure in patients with secundum ASD and PAH can be successfully performed in selected subjects and is associated with good outcomes. Early improvements in RVSP are seen in patients with moderate or severe PAH undergoing transcatheter ASD closure. Continued improvement in RVSP occurs in late follow-up. Despite decreases in the mean RVSP in late follow-up, many patients do not have complete normalisation of pressures.
