Hydatid cyst is a zoonosis caused by echinococcos granulosis. Incidence of the disease varies between 5 to 20 in 100 000 in most countries. Cardiac hydatid cysts are rare and comprise 0,5 to 2 % of all hydatid cyst cases. The most frequent location is the free wall of left ventricle and interventriculer septum. A hydatid cyst localized at the apex of left ventricle is an extremely rare occasion. Most of the patients with cardiac hydati-dosis are asymptomatic. We present a case of cardiac hydatid cyst localized at the left ventriculer apex who presented
with atrial fibrillation (AF) and symptoms of heart failure(HF). Hydatid cyst must be considered absolutely in the differantial diagnosis of cardiac cysts.
