Patent foramen ovale - Symptom

Alternative Names

PFO

Symptoms:

Infants with a patent foramen ovale and no other heart defects do not have symptoms.

Signs and tests:

An echocardiogram can be done to diagnose a PFO. If the PFO is not easily seen, a cardiologist can perform a "bubble test." Saline solution (salt water) is injected into the body. If a PFO exists, air bubbles will occur from the right to left side of the heart.
