Introduction:
Hydatid cyst disease (HCD), a zoonotic parasitic infection caused by Echinococcus granulosus, E. multilocularis, or E. vogeli, is a significant health problem and has a worldwide distribution with a higher incidence in underdeveloped and developing countries. Humans become intermediary carriers from consuming food contaminated with parasite eggs. The parasite embryo can reach the systemic circulation through the intestine and then reach any organ with a different prevalence. Multiple organ involvement can be seen in cases.[1] Cardiac hydatid cyst (CHC) is extremely rare and represents 0.5-2% of all human cases.[2]However, it can lead to severe and life-threatening complications. Occurrence in children is infrequent since the cyst grows slowly by about 1 cm per year.[3] The primary recommended treatment is surgery.
Here, we present a rare case of a hydatid cyst (HC) in childhood with cardiac involvement and intracardiac rupture that caused a true ventricular aneurysm treated with the Dor procedure for minimizing the akinetic tissues and restoring natural ventricular geometry.
