Summarize this article for a 10 year old
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 lesion is often accompanied by other congenital cardiac lesions.[2] It is classified as a critical congenital heart defect[3] accounting for less than 1% of all congenital heart defects presenting in around 1 per 200,000 live births.[4] Ebstein's anomaly usually presents with a systolic murmur (sometimes diastolic) and frequently with a gallop rhythm.[5]
