Just born 1 month baby patent foramen ovale normal

PFO is a physiological anatomical structure that exists in the fetal period. It can connect the two heart chambers and enable blood circulation. It is often not closed immediately after birth. Most infants close at about 2 months after birth, and no later than 1 year old.

Parents are advised to pay more attention to observation at ordinary times. Take the baby to the hospital regularly for cardiac ultrasound examination to monitor the closure of the PFO. If the baby still has PFO after 1 year old, surgery is needed as soon as possible.
