A case of cardiac hydatid cyst located in the interventricular septum

Cardiac hydatid cyst is a rather rare disease. Although cardiac hydatid cysts are usually asymptomatic, serious complications such as atrioventricular block, syncope, pericarditis, stenosis in cardiac valve orifices, and sudden death may develop due to the localization and size of the cyst. Early diagnosis and treatment are of utmost importance. In this report, we present a case of interventricular septum localized hydatid cyst presenting with syncope as referral symptom.
