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 ...

Around day 15 of development, the cells that will become the heart exist in two horseshoe shaped bands of the middle tissue layer , [27] and some cells migrate from a portion of the outer layer , the neural crest, which is the source of a variety of cells found throughout the body. On day 19 of development, a pair of vascular elements, the ...
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 ventricle affected becomes "atrialized" with thinner walls.
The majority of cases can be diagnosed prenatally during a routine anomaly scan. If evidence of a congenital heart disease is found, the diagnosis can be confirmed by a foetal echocardiogram . If it is not diagnosed prenatally, it may be diagnosed shortly after birth with physical examination, which would reveal cyanosis and murmur.
Ebstein's anomaly [31] – about 50% of individuals with Ebstein anomaly have an associated shunt between the right and left atria, either an atrial septal defect or a patent foramen ovale. [32] Fetal alcohol syndrome – about one in four patients with fetal alcohol syndrome has either an ASD or a ventricular septal defect. [33]
Those affected by arrhythmogenic cardiomyopathy may not have any symptoms at all despite having significant abnormalities in the structure of their hearts. [6] If symptoms do occur, the initial presentation is often due to abnormal heart rhythms (arrhythmias) which in arrhythmogenic cardiomyopathy may take the form of palpitations, or blackouts. [7]
