Lithium and Ebstein's anomaly.

The article deals with Ebstein's anomaly, lithium and their relationship. Some studies suggest that lithium might be involved as a teratogen increasing the incidence of Ebstein's anomaly in the offspring of female patients with manio-depressive psychosis and lithium-administered during pregnancy. The second part of the article contains data on the incidence of Ebstein's anomaly in the Czech Socialist Republic between 1960 and 1985. The results indicate a steady rise in the incidence of this congenital malformation over the above period of time.
