[Giant left ventricle cardiac hydatid cyst : report of a challenging case].

Hydatidosis is a potentially fatal parasitic disease where humans are an accidental host. The cardiac location is due to the development in the heart of the larval form of Taenia Echinococcus granulosus. We present the case of a patient with a history of pulmonary hydatid cysts who presented with atypical chest pain with a huge hydatid cyst of the anterior and lateral wall of the left ventricle of 80/66 mm in diameter responsible of a thinning of the wall of the left ventricle and close relationship with the anterior descending artery and the circumflex artery. The surgery under extracorporeal circulation reconstructed the wall of the left ventricle with a double patch.
