From May 1991 to July 2003, 19 patients (9 men and 10 women), of 30 years average age were operated in our department service for surgical cure of cardio-pericardial hydatid cysts. The TEE constitutes the examination of choice in the cardio-pericardial diagnosis of hydatid cyst. The surgery under CPB is the technique of choice, we practiced used 15 times. The left ventricular localization is most frequent. We deplore only death into post-operative immediate. The post-operative was course simple at the majority of our patients. 17 patients could be controlled remotely of the intervention with 35.5 months an average passing. We deplore 2 late deaths. No relapse was observed.
