[Myocardial biopsy in suspected myocardial sarcoidosis].

24 patients with pulmonary sarcoidosis stage I or II, who above all on account of changes of the ECG roused the suspicion of the presence of a sarcoidosis of the myocardium, finally underwent an invasive examination with laevocardiography, coronarography and biopsy of the endomyocardium. While the unaimed taking of tissue from the left ventricle did not result light-microscopically in a reference to granulomas or other inflammatory changes, the biopsy in a female patient, on purpose taken from a hypokinetic area of the left ventricle, showed epitheloid-cellular granulomas with giant-cells. Evaluating these results and reports in literatur, we came to the conclusion that findings typical for sarcoidosis are promising success only when taken from cardiographically suspicious areas of the myocardium.
