What happens when the fetal shunts dont close properly after birth?

When fetal shunts, such as the ductus arteriOSus and foramen ovale, do not close properly after birth, it can lead to abnormal blood flow patterns in the heart and lungs. This condition can cause complications like increased pulmonary blood flow, heart failure, or cyanosis, depending on the specific shunt involved. In some cases, medical intervention may be required to promote closure or manage symptoms. Persistent shunts can lead to long-term health issues if not addressed appropriately.
