[The finding of endocardial fibroelastosis in a 20-week-old fetus]

Endocardial fibroelastosis is a rare disease that only sporadically has been diagnosed prenatally. The cases reported so far were found after the second trimester of pregnancy. We report a case of endocardial fibroelastosis found in a 20-week fetus, in whom the diagnosis was performed by echocardiography and, after voluntary interruption of pregnancy, was confirmed by necroscopy and histology. Early intrauterine detection of endocardial fibroelastosis allows to plan pregnancy, modality of delivery and a possible therapy.
