Hydatid disease of the heart.

A 27-year-old physical education teacher, from a rural sheep farming area of South Africa, was referred following an isolated episode of collapse. Transthoracic echocardiography and MRI showed a cystic lesion under the septal leaflet of the tricuspid valve attached to the right ventricular wall. A provisional diagnosis of hydatid cyst was made. Hydatid serology was negative and there was no evidence of hydatidosis elsewhere. Preoperatively, the patient was treated with praziquantel and albendazole. Surgery was performed using cardiopulmonary bypass. Cyst was excised without any spillage. The patient was weaned off bypass without any support and made an uneventful recovery. Cytology and microbiology of the specimen confirmed hydatid pathology. This case describes excision of a right ventricular hydatid with techniques used to avoid spillage. It also describes an up-to-date antihelminthic therapy used in the management of hydatid cysts.
