The authors report two new cases of cardiac disease associated with distomatosis: one case of biventricular fibroblastic parietal endocarditis affecting mainly the left side in a young female of 26 years, and one case of cardiomyopathy with atrial endocardial fibrosis, affecting especially the left ventricle in a man of 47. Bearing in mind the five cases reported in the literature, the authors propose a classification of cardiac disorders supposed to be due to distomatosis using three groups (endocardial fibrosis, cardiomyopathy, myocarditis) and relate them to a common pathogenesis based on immuno-allergic theory.
