Ebstein's anomaly is a congenital heart defect in which the opening of the tricuspid valve is displaced towards the apex of the right ventricle of the heart. The International Statistical Classification of Diseases and Related Health Problems (most commonly known by the abbreviation ICD) provides codes to classify Diseases The International Statistical Classification of Diseases and Related Health Problems 10th Revision ( ICD -10) is a coding of diseases and signs symptoms abnormal findings Q00-Q89 - Congenital malformations and deformations (Q00-Q07 Nervous system ( Anencephaly and similar malformations The International Statistical Classification of Diseases and Related Health Problems (most commonly known by the abbreviation ICD) provides codes to classify Diseases The following is a list of codes for International Statistical Classification of Diseases and Related Health Problems.

Presentation
The annulus of the valve is still in the normal position. The valve leaflets, however, are to a varying degree, attached to the walls and septum of the right ventricle. There is subsequent atrialization of a portion of the morphologic right ventricle (which is then contiguous with the right atrium). This causes the right atrium to be large and the anatomic right ventricle to be small in size.
Risk factors
There may be an increased risk of this abnormality in infants of women taking lithium during the first trimester of pregnancy, and in those with Wolff-Parkinson-White syndrome. Lithium in pharmacology refers to use of the Lithium Ion, Li+ as a drug
History
Ebstein's anomaly was named after Wilhelm Ebstein. Wilhelm Ebstein ( November 27, 1836, Jauer, Prussian Silesia - October 22, 1912) was a German physician [1][2]
Related abnormalities
While Ebstein's anomaly is defined as the congenital displacement of the tricuspid valve towards the apex of the right ventricle, it is often associated with other abnormalities.
Anatomic abnormalities
Typically, there are anatomic abnormalities of the tricuspid valve, with enlargement of the anterior leaflet of the valve.
About 50% of individuals with Ebstein's anomaly have an associated shunt between the right and left atriums, either an atrial septal defect or a patent foramen ovale. Atrial septal defect ( ASD) is a form of congenital heart defect that enables blood flow between the left and right atria via the Interatrial septum. Atrial septal defect ( ASD) is a form of congenital heart defect that enables blood flow between the left and right atria via the Interatrial septum.
Electrophysiologic abnormalities
About 50% of individuals with Ebstein's anomaly have evidence of Wolff-Parkinson-White syndrome, secondary to the atrialized right ventricular tissue.
