Patent vessel in the fetal heart connects the pulmonary trunk to the descending aorta.
Shortly after birth, changes normally provoke contraction, closure, and fibrosis:
Isolated patent ductus arteriosus (PDA), an unanticipated event
PDA, as part of a larger congenital cardiac anomaly, may be diagnosed by US during pregnancy.
Small, asymptomatic shunts may not need closure.
Close follow-up with plans for early surgical closure
CHF may cause decrease in glomerular filtration rate and urinary output.
Indomethacin may cause GI bleeding.
