This study illustrated 10 cases of sarcoidosis symptomatic cardiomyopathy. All sarcoidosis were confirmed by histology. One was revealed by cardiological signs. Extra-cardiologic manifestations were non specific, as well cardiological and electrical signs. ECG were abnormal in only 70% of cases. Echocardiography and thallium scintigraphy with dipyramidole test were always abnormal. No sudden death appeared in our series. As opposed to all cases in literature, all patients, but one, responded positively to corticotherapy. These results can be explained by high doses of prednisolone associated, when non effective, to another immunosuppressive agent.
