Patent foramen ovale (PFO) is a normal fetal communication. The opening closes after birth in the majority of people, but may remain in up to 20 % of adults. The embryology of the PFO shapes the anatomy of the communication. This influences the shape of the communication after birth, and the best method of transcatheter closure.
