Surgical experience with thrombotic and fibrotic forms of non-tropical eosinophilic endomyocardial disease

Surgical treatment in 8 cases of non-tropical eosinophilic endomyocardial diseases with (4 patients) and without (4 patients) eosinophilia is reported. Follow-up results (1 to 4 years) in the 6 survivors, including hemodynamic re-study, were excellent even in patients operated on in the thrombotic stage (3) or with hypereosinophilia (2), or with dominant right ventricular involvement (3). Two-dimensional echocardiography gave the correct description of the pathologic stage and ventricular involvement in 6 of the 8 cases before catheterization.
