Primary Cardiac Hydatid Cyst

We report 3 patients with primary cardiac hydatid cysts, all of which were located on the wall of the right ventricle. In one case, an intramyocardial cyst protruded into the right ventricular chamber and in the other 2 cases, cysts protruded into the intrapericardial space. The diagnosis was confirmed by serologic tests, two-dimensional echocardiography, tomographic scanning and cardiac angiography. The patients underwent successful enucleation of the cysts with the aid of cardiopulmonary bypass. There was no morbidity or mortality and late results were satisfactory.
