title: Unusual location of hydatid cyst: the posterior leaflet of tricuspid valve.
abstract: Hydatid Cyst disease involves the heart in 0.02-2% of the cases. It can appear with symptoms very similar to coronary artery disease, cardiac valvular disease and pericarditis. We present a case of hydatid cyst that was located on the posterior tricuspid leaflet and that caused tricuspid regurgitation in 37 year old female patient who has gone through hydatid cyst excision from the bilateral lungs with median sternotomy 2 years ago. In addition to the right atrial and ventricular dilatation, second degree tricuspid regurgitation and significant pulmonary hypertension was found. The 2 x 2 cm smooth surfaced mass was resected from the posterior leaflet of the tricuspid valve and the defect was closed with suture with the aid of cardiopulmonary bypass. The patient followed with long term albendazole treatment. Cardiac echinococcosis should be kept in mind in some patients throughout their life with a history of previous hydatid cyst disease. Surgical excision without rupture is the treatment of choice for cardiac hydatid cyst, with following medical therapy in order to prevent recurrence.
