[Ebstein's anomaly in adult patients: diagnostic and prognostic profile with regard to two cases (author's transl)].

Two cases of Ebstein's anomaly in apparently asymptomatic adult patients are described. The chances of non invasive recognition of the malformation by means of electro-vectorcardiography and echocardiography are discussed. Unlike their useful diagnostic contribution, their prognostic valve seems to be negligible. For this purpose clinical course of malformation would remain very important, even if some unusual electrocardiographic and radiological features can provide interesting informations.
