The incidence of cardiac hydatid disease, caused by Echinococcus granulosus, is 0.5% to 2% in the sheep grazing areas of developing and under-developed countries. The cyst can be present in the interventricular septum in 5% to 9% of the patients, along with conduction block or arrythmia. Intraoperative transesophageal echocardiography (TEE) can guide the surgeon in cyst localization and excision. This image review highlights the TEE findings in a young patient with multiple hydatid cysts of the interventricular septum, and the cyst membrane adhering to the septal tricuspid leaflet.
