Coronary angiographic features in endomyocardial fibrosis

Selective coronary cineangiography was performed in 24 patients with angiographic features suggestive of endomyocardial fibrosis (EMF). 8 patients had right ventricular disease, 2 had left ventricular disease and 14 had biventricular disease. The abnormal features found in the coronary arteries of these patients were: (a) vascular blush or neovascularity in 54.2% of patients and (b) localized ventricular filling from the region of the blush in 16.7%. Generalized tortuosity of the coronary arteries, considered to be a nonspecific change associated with ventricular enlargement and hypertrophy, was seen in 50%. This study lends support to one of the hypotheses which implies the role of mural thrombus in the evolution of the pathological lesion of EMF.
