Is patent foramen ovale hereditary

Patent foramen ovale (PFO) is not directly hereditary, but there can be a genetic predisposition to certain heart conditions that may include PFO. It is a common anatomical variant found in the general population, occurring in about 25% of adults. While it can run in families, the presence of a PFO itself is not strictly inherited. Other factors, such as environmental influences, may also play a role in its occurrence.
