Hydatid disease is a zoonotic infection caused by the metacestode stage of Echinococcus granulosus, E. multilocularis, or E. vogeli (Taeniadae family). Dogs and cats are the primary carriers of this parasite. Humans can be infected as intermediary carriers after ingestion of the parasite eggs in unwashed or uncooked vegetables [1, 2]. Solitary cysts occur in almost 60% of the cases [3].

Cardiac involvement is seen in only 0.5 to 2% of patients with hydatid disease [4, 5, 6], and the location of a hydatid cyst in the interventricular septum is just 4% of cardiac cases [4, 5, 6].

The diagnosis is by clinical suspicion, relevant serological tests, and cardiac imaging by various modalities like echocardiography which is highly sensitive and specific in the diagnosis of hydatid cysts [1].

Herein, we report a case of a giant cardiac hydatid cyst involving the interventricular septum and its surgical management.
