Clinical and pathological abnormalities of the heart that may have major functional significance in those conditions were studied in collagen disease (total 242 cases). 1. atypical verrucous endocarditis (Libmann-Sacks) were found in 2 cases with loupus erythematosus (25 cases) and in 1 case with scleroderma (3 cases). 2. Rheumatoid nodules were not seen in the heart of rheumatoid arthritis patients (9 cases). 3. The most frequent findings in the heart with collagen diseases were pericarditis, fibrous scarring of the heart muscle, focal inflammation and vasculitis is similar to periarteritis nodosa or endoarteritis obliterans. 4. Morphological changes of the A-V node were found in patients who had A-V dissociation or A-V block before death. Heart muscle infarctions were found in 2 cases.

Specimens from 300 patients were studied using five to nine aerobic and anaerobic culture media, including five that were hypertonic, Groups studied included fever of unknown origin, suspected endocarditis, endocarditis during therapy, bacteremia during therapy, abscess and cellulitis, presumed infectious arthritis, renal transplantation during rejection, collagen disease, sarcoidosis, lymphoma, and colitis. Isolates in hypertonic media were reverted to parent form by agar passage. In only 5% of these selected cases were organisms found in hypertonic, but not conventional, media that appeared on the basis of repeated isolation and/or serological studies to come from the patient. Nine of the 16 appeared to be of major significance. The two groups in which use of highly enriched, hypertonic media seemed most helpful were suspected endocarditis and undefined meningitis with negative cultures using standard media. The most effective of the hypertonic media used was 0.3 M sucrose in brain heart infusion with 20% horse serum. In most instances, the organism grew only in the hypertonic sucrose, and in most cases it appeared in conventional rather than aberrant form. Hypertonic media, especially 0.3 M sucrose, are of substantial helpin a small number of carefully selected cases.

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.
