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 ...
English: 9-year-old girl with Ebstein's anomaly and Mahaim accessory pathway. ECGs recorded during sinus rhythm showing minimal pre-excitation, and during tachycardia (antedromic AVRT) showing maximal pre-excitation with LBBB morphology
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.
If a cardiac anomaly is suspected in a routine ultrasound during pregnancy, often a perinatologist (maternal-fetal specialist) will perform a fetal echocardiogram (noninvasive ultrasound of the fetus heart), which may be able to confirm a diagnosis of HRHS. This can help with possible options for treatment.

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 ().
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.
Ebstein's anomaly has an increased risk of accessory pathways as well. Non-cardiac causes [ 44 ] [ 47 ] Common non-cardiac causes include respiratory arrest , diabetes , certain medications , and blunt trauma (especially to the chest).
