Six cases of Ebstein's malformation are reported. The notable clinical features seen in four patients were gross enlargement of the
heart, venous congestion and marked hepatosplenomegaly. There was complete heart block in one patient and auricular fibrillation in the remaining three. The unusual pathologic features in the four cases that came to necropsy were the large pericardial effusions associated with the cardiomegaly, the absence of an atrial septal defect or patent foramen ovale, the gross enlargement of liver with cirrhotic changes and the large spleen. Histologic examination of heart muscle revealed certain unusual features which are described.
The above survey based on a study of single stool specimens from 569 patients, drawn from a hospital population belonging to different ethnic groups and having different cultural backgrounds, failed to indicate an association between intestinal helminth infection and eosinophilic lung. The higher prevalence of eosinophilic lung in Indians than in the other ethnic groups, as reported previously, cannot be explained on a basis of differences in the prevalence of the intestinal helminths, Ascaris lumbricoides, hookworm, Trichuris trichiura and Strongyloides stercoralis.
