title: [Right intraventricular biopsy. Indications and results. 116 cases].
abstract: The indications for endomyocardial biopsy were evaluated from 116 consecutive cases. The diagnostic value of this invasive but well tolerated procedure was in agreement with data from the literature. An accurate diagnosis, unforseeable in 8% of the patients, was established in 12%. The diagnosis of apparently primary myocardiopathy with ventricular dilatation was confirmed in 45 out of 59 cases; there were 3 cases of myocarditis, 3 cases of restrictive cardiopathy (haemochromatosis, fibroplastic endocarditis) and 1 case of hypertrophic cardiopathy. No tissue abnormality was noted in 6 cases. An accurate diagnosis was obtained by biopsy in 1 case of "eosinophilic lung" without overt cardiac involvement. In malignant diseases treated with anthracyclines in doses reaching maximal theoretical total dosage (30 patients), severe tissue lesions were present in 10% of the cases, incipient haemochromatosis in 16.6% and subendocardial fibrosis in 3.3%. However, total doses of up to 600 mg/m2 could be administered to 90% of the patients. Myocardial lesions could be demonstrated in 1 of 2 patients with collagen disease. Endomyocardial biopsy therefore seems to be justified in myocardiopathies with ventricular dilatation, in some collagen diseases with a tendency to cardiac involvement and to monitor treatment with anthracyclines in total doses higher than the theoretical maximum dosage.
