| Explanation | [[Explanation:: Ebstein’s anomaly is a congenital heart disease characterized by abnormalities of the tricuspid valve, the right atrium, and the right ventricle. Apical displacement of the tricuspid valve leaflets leads to an atrialized right ventricle that is often too small to circulate sufficient blood. Ebstein's anomaly is relatively rare with an incidence of 1 in 200,000. Patients with severe forms present with cyanosis, dyspnea, and failure to thrive. The majority of these patients have early manifestation of the disease following close of the PDA and may be dependent on the PDA for pulmonary blood flow. Nonetheless, it is not uncommon that manifestations be delayed until childhood, adolescence, and even early adulthood. The development of Ebstein's anomaly has been associated with lithium administration during pregnancy particularly in the first trimester. Lithium is a mood stabilizer indicated for bipolar disorder, which is characterized by alternating symptoms of depression and episodes of mania. Manic episodes are usually described as significant distractibility, irresponsibility, hedonistic behavior, grandiosity, racing thoughts, psychomotor agitation, insomnia, and talkativeness or pressured speech. |
