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 that the ...
The tricuspid valve can be affected by rheumatic fever, which can cause tricuspid stenosis or tricuspid regurgitation. [8] Some individuals are born with congenital abnormalities of the tricuspid valve. Congenital apical displacement of the tricuspid valve is called Ebstein's anomaly and typically causes significant tricuspid regurgitation.
In The Framingham Heart Study, presence of tricuspid regurgitation of mild severity or greater, was present in about 14.8% of men and 18.4% of women. [20] Mild tricuspid regurgitation tends to be common and, in the presence of a structurally normal tricuspid valve apparatus, can be considered a normal variant. [21]
Ebstein's anomaly is an abnormality of the tricuspid valve, and its presence can lead to tricuspid valve regurgitation. [ 16 ] [ 18 ] A bicuspid aortic valve [ 16 ] is an aortic valve with only 2 cusps as opposed to the normal 3.
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 occurs during prenatal development, when the heart does not finish ...
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.
Mitral valve stenosis is an uncommon cardiac abnormality that can occur at birth (congenital) or develop later in life (acquired). [89] [12] The aberrant narrowing of the mitral valve's opening characterizes this condition. [89] [12] There are two versions of this condition known as congenital and acquired characterized by different symptoms. [12]
Tricuspid valve stenosis itself usually does not require treatment. If stenosis is mild, monitoring the condition closely suffices. However, severe stenosis, or damage to other valves in the heart, may require surgical repair or replacement. The treatment is usually by surgery (tricuspid valve replacement) or percutaneous balloon valvuloplasty ...
