  2. Atrial septal defect - Wikipedia

    en.wikipedia.org/wiki/Atrial_septal_defect

    Atrial septal defect (ASD) is a congenital heart defect in which blood flows between the atria (upper chambers) of the heart.Some flow is a normal condition both pre-birth and immediately post-birth via the foramen ovale; however, when this does not naturally close after birth it is referred to as a patent (open) foramen ovale (PFO).

  3. Foramen ovale (heart) - Wikipedia

    en.wikipedia.org/wiki/Foramen_ovale_(heart)

    PFO has long been studied because of its role in paradoxical embolism (an embolism that travels from the venous side to the arterial side). This may lead to a stroke or transient ischemic attack. Transesophageal echocardiography is considered the most accurate investigation to demonstrate a patent foramen ovale. A patent foramen ovale may also ...

  4. Fossa ovalis (heart) - Wikipedia

    en.wikipedia.org/wiki/Fossa_ovalis_(heart)

    An unfused fossa ovalis is called a patent foramen ovale. Depending on the circumstances, a patent foramen ovale may be completely asymptomatic, or may require surgery. [ 1 ] The limbus of fossa ovalis ( annulus ovalis ) is the prominent oval margin of the fossa ovalis in the right atrium.

  5. Patent ductus arteriosus - Wikipedia

    en.wikipedia.org/wiki/Patent_ductus_arteriosus

    Patent ductus arteriosus (PDA) is a medical condition in which the ductus arteriosus fails to close after birth: this allows a portion of oxygenated blood from the left heart to flow back to the lungs from the aorta, which has a higher blood pressure, to the pulmonary artery, which has a lower blood pressure.

    Dan Kenny, 40, felt dizzy and tired at the end of his day. Doctors determined he was having a stroke — and found he had a PFO, an undiagnosed hole in his heart.

  7. Paradoxical embolism - Wikipedia

    en.wikipedia.org/wiki/Paradoxical_embolism

    Although closure of a patent foramen ovale or atrial septal defect theoretically removes the pathway for an arterial embolus to enter venous circulation and cause a paradoxical embolism, data suggests that closing intracardiac shunts is no more effective than medical management alone in preventing strokes. [2]

  8. Foramen secundum - Wikipedia

    en.wikipedia.org/wiki/Foramen_secundum

    Once a baby is born, blood should flow through the lungs, which now function to provide oxygen to the blood. The foramen secundum and foramen ovale act as a shunt where blood bypasses the lungs and does not become oxygenated. To provide proper blood flow as a newborn, the foramen secundum and foramen ovale must close at birth.
