  2. Tetralogy of Fallot - Wikipedia

    en.wikipedia.org/wiki/Tetralogy_of_Fallot

    a bicuspid pulmonary valve, in 60%; right-sided aortic arch, in 25%; coronary artery anomalies, in 10%; a patent foramen ovale or atrial septal defect, in which case the syndrome is sometimes called a pentalogy of Fallot [46] an atrioventricular septal defect; partially or totally anomalous pulmonary venous return

  3. 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).

  4. Ventricular outflow tract obstruction - Wikipedia

    en.wikipedia.org/wiki/Ventricular_outflow_tract...

    The left side of the heart is more muscular than the right side of the heart. It pumps oxygenated blood from the lungs into the aorta to perfuse the rest of the body. [4] When the heart has to pump against increased resistance, or afterload, as in the case of a ventricular obstruction, it compensates by growing in size. This adaptation is ...

  5. 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.

  6. Pulmonary atresia with ventricular septal defect - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_atresia_with...

    Heart sounds of a ventricular septal defect patient. The condition consists of atresia affecting the pulmonary valve and a hypoplastic right ventricular outflow tract. The ventricular septal defect doesn't impede the in and outflowing of blood in the ventricular septum, which helps it form during fetal life.

  7. Lutembacher's syndrome - Wikipedia

    en.wikipedia.org/wiki/Lutembacher's_syndrome

    Lutembacher's syndrome is a very rare [1] form of congenital heart disease that affects one of the chambers of the heart (commonly the atria) as well as a valve (commonly the mitral valve). It is commonly known as both congenital atrial septal defect (ASD) and acquired mitral stenosis (MS) . [ 2 ]

  8. Persistent fetal circulation - Wikipedia

    en.wikipedia.org/wiki/Persistent_fetal_circulation

    Other echocardiographic findings in PPHN include right ventricular hypertrophy, deviation of the ventricular septum, tricuspid regurgitation, and shunting at the patent foramen ovale. [ 3 ] Other clinical signs that may signify PPHN are respiratory distress, partial pressure of oxygen greater than 100 mg and elevated partial pressure of carbon ...

  9. Eisenmenger syndrome - Wikipedia

    en.wikipedia.org/wiki/Eisenmenger_syndrome

    Eisenmenger syndrome or Eisenmenger's syndrome is defined as the process in which a long-standing left-to-right cardiac shunt caused by a congenital heart defect (typically by a ventricular septal defect, atrial septal defect, or less commonly, patent ductus arteriosus) causes pulmonary hypertension [1] [2] and eventual reversal of the shunt into a cyanotic right-to-left shunt.
