A cardiac hydatid cyst involving the basal interventricular septum causingbiventricular outflow tract obstruction

We report a case of a 37-year-old sheep-raising man with a cardiac hydatid cyst involving the basal interventricular septum causing biventricular outf low obstruction. He suffered from multi-organ hydatidosis and underwent cer ebral hydatid cyst extirpation and right nephrectomy for renal echinococcos is. The diagnosis of the cyst was obtained by echocardiography and magnetic resonance imaging. The diagnosis was confirmed by positive hemagglutinatio n test. He was operated on for cardiac hydatid cyst using enucleation and c apitonnage procedure under extracorporeal circulation. The morbidity was co mplete atrioventricular block, necessitating VDD pacemaker implantation. Th is was followed by medical treatment with albendazole (400 mg/day).
