    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. Tetralogy of Fallot - Wikipedia

    en.wikipedia.org/wiki/Tetralogy_of_Fallot

    Fallot was the first to elegantly describe the four key features that differentiate it from other cyanotic cardiac conditions, and was prominent in the disqualification of a patent foramen ovale as a fifth feature. Fallot initially referred to it as "La maladie bleue", which is French for "the blue disease" or "cyanose cardiaque", translating ...

  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. Balloon septostomy - Wikipedia

    en.wikipedia.org/wiki/Balloon_septostomy

    Balloon septostomy is the widening of a foramen ovale, patent foramen ovale (PFO), or atrial septal defect (ASD) via cardiac catheterization (heart cath) using a balloon catheter. This procedure allows a greater amount of oxygenated blood to enter the systemic circulation in some cases of cyanotic congenital heart defect ( CHD ).

  6. Paradoxical embolism - Wikipedia

    en.wikipedia.org/wiki/Paradoxical_embolism

    These routes include moving through a patent foramen ovale (a congenital hole connecting the right and left atria of the heart), a ventricular septal defect (a congenital hole connecting the ventricles), or a pulmonary arteriovenous fistula, where arteries in the lungs connect directly to veins without capillaries in between.

    The operation is performed under general anesthesia. The four pulmonary veins are reconnected to the left atrium, and any associated heart defects such as atrial septal defect, ventricular septal defect, patent foramen ovale, and/or patent ductus arteriosus are surgically closed. With obstruction, surgery should be undertaken urgently.

  8. dextro-Transposition of the great arteries - Wikipedia

    en.wikipedia.org/wiki/Dextro-Transposition_of...

    The foramen ovale is a hole in the atrial septum which allows blood from the right atrium to flow into the left atrium; after birth, the left atrium will be filled with blood returning from the lungs and the foramen ovale will close. The ductus arteriosus is a small, artery-like structure which allows blood to flow from the trunk of the ...

  9. Atrial septostomy - Wikipedia

    en.wikipedia.org/wiki/Atrial_septostomy

    Atrial septostomy is a surgical procedure in which a small hole is created between the upper two chambers of the heart, the atria.This procedure is primarily used to palliate dextro-Transposition of the great arteries or d-TGA (often imprecisely called transposition of the great arteries), a life-threatening cyanotic congenital heart defect seen in infants.
