Purpose: To determine through conventional radiology the type of ventricular involvement in endomyocardial fibrosis (EMF).
Methods: We analyzed 56 cases with EMF confirmed by angiocardiography and 9 by postmortem study, aged between 16 and 56 years (mean 32); there were 42 females. Only one radiologist analyzed X-rays without any knowledge of the cineangiography findings.
Results: The right side of the heart was primarily involved in 9 patients and the cardiac silhouette was characteristically globular and had oligemic pulmonary fields (66.66%). The cardiothoracic ratio was 0.62 +/- 0.11. Out of 9 patients, 8 were female. The left side of the heart was established as being primarily involved in 11 cases and simulated rheumatic mitral disease. The cardiothoracic ratio was 0.51 +/- 0.09 and there were increased pulmonary fields in 63.6%. The biventricular disease occurred in 36 cases. There were radiologic findings of right and left side. The cardiothoracic ratio was 0.63 +/- 0.06 and there was oligemic pulmonary fields in 38.8%, increased pulmonary fields in 33.3% and was normal in 27.7%. There were 4:1 females.
Conclusion: The radiological study is fundamental in the initial diagnosis of EMF. The type of involvement could be done in 66.07% of all cases by chest X-ray.
