Abstract: The term isomerism refers to symetrical development of organs that are normally asymetrical. These characterize the heterotaxy syndromes. In heterotaxy syndromes the position of the organs are different from situs solitus. We present two cases of atrial isomerism which is a complex anomaly and rather difficult to diagnose in utero. For both cases, the death of the fetuses were achieved at 24 weeks of gestation. We concluded that survival of children with left atrial isomerism is higher than those with right isomerism. In this respect, the second case shows to become more appropiate for surgery.
