Abstract
We present the cases of three children with patent ductus arteriosus (PDA), pulmonary arterial
hypertension (PAH), and desaturation. One of them had desaturation associated with atrial
septal defect (ASD). His ASD, PAH, and desaturation improved after successful device closure
of the PDA. The other two had desaturation associated with Down syndrome. One had
desaturation only at room air oxygen (21% oxygen) but well saturated with 100% oxygen,
subsequently underwent successful device closure of the PDA. The other had experienced
desaturation at a younger age but spontaneously recovered when he was older, following
attempted device closure of the PDA, with late embolization of the device. (Cardiol J 2012; 19,
