A case report of a 35-year old woman is presented who continued a coumarin therapy unconscious of an early pregnancy up to day 61. At term she delivered a baby with tetralogy of Fallot, up to now not mentioned in the symptom complex of malformations due to a coumarin therapy. In the case presented the typical symptoms of a warfarin embryopathy including a chondrodysplasia punctata and other morphological changes were lacking. Although some cases of cardiac malformations have been reported in literature following coumarin therapy in early pregnancy, a causal connection could not be confirmed.
