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 ...
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 ...
Tricuspid stenosis – Narrowing of the tricuspid valve opening that reduces blood flow through the valve. Ebstein's anomaly – A congenital heart defect that results in the tricuspid valve leaflets being deeper in the heart (toward the apex) than normal. The annulus of the valve is in the correct position, however, and the portion of the ...
Pulmonary valve defects resulting in tricuspid regurgitation, a common effect of pulmonary stenosis, can cause this increase in muscle mass. [5] Atrial septal defect An atrial septal defect is a hole in the septum that divides the right and left atria (the upper two chambers) of the heart. In the heart of a developing fetus, there are several ...
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 ...
3) Abnormalities of the mitral and/or tricuspid valves. [ 1 ] [ 2 ] AVCD is caused by an abnormal or inadequate fusion of the superior and inferior endocardial cushions with the mid portion of the atrial septum and the muscular portion of the ventricular septum . [ 3 ]
Atrioventricular septal defect (AVSD) is an uncommon congenital heart condition characterized by faulty development of the heart's septa and valves. [88] [12] Congestive heart failure is common in infants with the entire version of the condition. [88] [12] Fluid builds up in other parts of the body, particularly the lungs.
English: 12-lead ECG of a woman with Ebstein's anomaly (a congenital heart defect in which the opening of the tricuspid valve is displaced towards the apex of the right ventricle of the heart, resulting in a large right atrium). The ECG shows signs of right atrial enlargement, best seen in V1.
