|Prompt=A 1-year-old boy is brought by her mother to the ER because of difficulty breathing and cyanosis. The pediatrician on call orders an echocardiogram in order to confirm the diagnosis. The pediatrician on call is a professor at a prestigious university; therefore he uses his radiologic findings to create a picture of the pathophysiology behind the cardiologic malformation.  The picture is shown below. Upon interrogation the mother states that he consumed a medication during her pregnancy to treat a psychiatric condition. She states that she started receiving prenatal care during the third trimester of pregnancy. Which of the following clinical presentations in her mother made her take the drug associated with the child’s condition?

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.

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.
Educational Objective: Lithium is a mood stabilizer indicated for bipolar disorder. Lithium administration during pregnancy is associated with the development of Ebstein's anomaly, especially when administered during the first trimester. Bipolar disorder classically presents with alternating symptoms of depression and episodes of mania.
