Subendocardial hydatid . cysts may rupture into the right or left chamber of the heart to produce pulmonary or systemic embolisation.' Few cases have been reported,2 and I believe that this case is the first to be reported in the United Kingdom in which a primary hydatid cyst in the interventricular septum caused multiple emboli in the pulmonary and systemic arterial circulation. The electrocardiographic changes may have been due to embolisation of the coronary vessels, but direct damage to the conducting pathway within the interventricular septum is more likely. In endemic areas hydatid disease should be considered as a possible cause of emboli, especially as subsequent signs of anaphylaxis may be misinterpreted and treated incorrectly. Echocardiography is the imaging technique of choice to detect intracardiac echinococcal cysts.3
