Hydatid disease remains endemic in some parts of the world. Cardiac
hydatidosis with multivisceral involvement is uncommon but potentially fatal. We report the case of a 36-year-old Tunisian woman admitted with
chest pain and T-wave inversion in the inferior leads on her electrocardiogram. Transthoracic echocardiography revealed a large
hydatid cyst in the epicardium throughout the left ventricle. Thoraco-abdominal computerized tomography (CT) scan showed several
hydatid cysts in the left lung, the liver, and in both breasts. After one week of
albendazole treatment, surgical excision of the cardiac
cyst on
cardiopulmonary bypass was carried out as well as excision of the pulmonary and
breast cysts. The postoperative course was uneventful and
albendazole treatment was continued for six months. Though hydatid cardiac involvement is very rare, it should be considered in the differential diagnosis of atypical
chest pain in young patients, especially those living in regions where
hydatid disease is endemic.
