Abstract The authors present three cases of cardiac tumors: two primary ; one secondary to osteogenic sarcoma and a case of echinococcus granulosus. Three of the patients were examinated by mono and two dtmensional echocadiography; only one by mono-dimensional echocardiography. Echocardiography was diagnosticallv resolutiue in all the cases, so it allowed to prexise the clinical diagnosis and to direct the patients to the cardio surgeon, if it was the case, supplying with informations that could not have been obtained by other non inoasiue methods. It is clear how, suspecting an intracardiac tumor,: it is nexessary to extend the routine echocardiographic examination also to the four apical chambers, thus obtaining a wider source of informations.
