  2. Hypoplastic right heart syndrome - Wikipedia

    en.wikipedia.org/wiki/Hypoplastic_right_heart...

    When the right side of the heart is more underdeveloped than the left side, this is known as hypoplastic right heart syndrome. HRHS is known for the pulmonary valve, the tricuspid valve, right ventricle, and the pulmonary artery all failing to form properly. HRHS also causes the right ventricle to be a fair amount smaller than the left side. [3]

  3. Ebstein's anomaly - Wikipedia

    en.wikipedia.org/wiki/Ebstein's_anomaly

    Cardiology. Ebstein's anomaly is a congenital heart defect in which the septal and posterior leaflets of the tricuspid valve are displaced downwards towards the apex of the right ventricle of the heart. [1] EA has great anatomical heterogeneity that generates a wide spectrum of clinical features at presentation and is complicated by the fact ...

  4. Tricuspid valve - Wikipedia

    en.wikipedia.org/wiki/Tricuspid_valve

    The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...

  5. Tricuspid regurgitation - Wikipedia

    en.wikipedia.org/wiki/Tricuspid_regurgitation

    Tricuspid regurgitation (TR), also called tricuspid insufficiency, is a type of valvular heart disease in which the tricuspid valve of the heart, located between the right atrium and right ventricle, does not close completely when the right ventricle contracts (systole). TR allows the blood to flow backwards from the right ventricle to the ...

  6. Tricuspid atresia - Wikipedia

    en.wikipedia.org/wiki/Tricuspid_atresia

    Medical genetics. Tricuspid atresia is a form of congenital heart disease whereby there is a complete absence of the tricuspid valve. [2] Therefore, there is an absence of right atrioventricular connection. [2] This leads to a hypoplastic (undersized) or absent right ventricle. This defect is contracted during prenatal development, when the ...

  7. Right ventricular hypertrophy - Wikipedia

    en.wikipedia.org/wiki/Right_ventricular_hypertrophy

    Right ventricular hypertrophy (RVH) is a condition defined by an abnormal enlargement of the cardiac muscle surrounding the right ventricle. The right ventricle is one of the four chambers of the heart. It is located towards the right lower chamber of the heart and it receives Deoxygenated blood from the right upper chamber (right atrium) and ...

  8. Bicuspid aortic valve - Wikipedia

    en.wikipedia.org/wiki/Bicuspid_aortic_valve

    Bicuspid aortic valve (BAV) is a form of heart disease in which two of the leaflets of the aortic valve fuse during development in the womb resulting in a two-leaflet (bicuspid) valve instead of the normal three-leaflet (tricuspid) valve. BAV is the most common cause of heart disease present at birth and affects approximately 1.3% of adults. [2]

  9. 3C syndrome - Wikipedia

    en.wikipedia.org/wiki/3c_syndrome

    CCC dysplasia, Craniocerebellocardiac dysplasia[1] or Ritscher–Schinzel syndrome, [2] Gene expression pattern of the KIAA0196 gene. Specialty. Medical genetics. 3C syndrome is a rare condition whose symptoms include heart defects, cerebellar hypoplasia, and cranial dysmorphism. It was first described in the medical literature in 1987 by ...
