[Cardiac hydatidosis: Report of one case].

Hydatidosis is an endemic zoonosis in Chile. We report a 48-year-old former slaughterman, with a previous history of pulmonary hydatidosis, who presented a stroke without associated cardiovascular symptoms. An echocardiogram revealed a tumor mass with cystic features in the left ventricle. The patient was operated and the cyst was successfully excised. During the follow up, the patient remains asymptomatic.
