  2. Transposition of the great vessels - Wikipedia

    The severity of symptoms depends on the type of TGV, and the type and size of other heart defects that may be present (ventricular septal defect, atrial septal defect, or patent ductus arteriosus). Most babies with TGA have blue skin color (cyanosis) in the first hours or days of their lives, since dextro-TGA is the more common type.

  3. Vein of Galen aneurysmal malformations - Wikipedia

    en.wikipedia.org/wiki/Vein_of_Galen_aneurysmal...

    The heart failure is due to the size of the arteriovenous shunt that can steal 80% or more of the cardiac output, with large volumes of blood under high pressure returning to the right heart and pulmonary circulation and sinus venosus atrial septal defects. [4] [5] It is also the most common cause of death in such patients. [6]

  4. 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).

    Examples of conditions in which CMR is often used include tetralogy of Fallot, transposition of the great arteries, coarctation of the aorta, single ventricle heart disease, abnormalities of the pulmonary veins, atrial septal defect, connective tissue diseases such as Marfan syndrome, vascular rings, abnormal origins of the coronary arteries ...

  6. Fossa ovalis (heart) - Wikipedia

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

    This pouch can protrude into the right atrium or the left atrium. The cause of this aneurysm is the result of abnormal, increased pressure within the heart. Even if the foramen ovale does seal shut, an aneurysm may occur, usually on the side of the right atrium. If the aneurysm stretches too far, it can narrow the opening of the inferior vena ...

  7. Interatrial septum - Wikipedia

    en.wikipedia.org/wiki/Interatrial_septum

    An Atrial septal defect is a relatively common heart malformation that occurs when the interatrial septum fails to develop properly. Persistence of the ostium secundum is the most common atrial septal defect. [3] Additionally, in a subset of the population, the foramen ovale is not overtly patent but the two septa have not fused.

  8. Ostium primum atrial septal defect - Wikipedia

    en.wikipedia.org/wiki/Ostium_primum_atrial...

    The ostium primum atrial septal defect is a defect in the atrial septum at the level of the tricuspid and mitral valves. This is sometimes known as an endocardial cushion defect because it often involves the endocardial cushion, which is the portion of the heart where the atrial septum meets the ventricular septum and the mitral valve meets the tricuspid valve.

  9. 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.
