The clinical and autopsy data of nine cases of endomyocardial fibrosis encountered over a period of 11 years are presented. These account for nearly 24% of primary cardiomyopathies and 0.8% of cardiac diseases seen at autopsy. There were four cases with biventricular endomyocardial fibrosis, three with a predominantly left and two with a predominantly right ventricular affection. There was no correlation between the clinical data and the autopsy pattern of endomyocardial fibrosis; all of them presented as congestive cardiac failure.
