Cardiac Hydatid Cyst: A Rare Presentation of Echinococcal Infection.

ABSTRACT:

Background

Cardiac hydatid disease is rare, comprising only 0.5% to 2% of all hydatid disease cases. Symptoms depend on the cyst's location, size, and impact on surrounding structures.

Case summary

We report a case of a middle-aged man with recurrent palpitations and shortness of breath. Electrocardiogram, during palpitation episodes, showed ventricular tachycardia. Further investigations confirmed a large hydatid cyst attached to the free wall of the left ventricle. Surgical excision led to an excellent clinical outcome.

Discussion

Hydatid disease, caused by Echinococcus granulosus, most commonly affects the liver or lungs. Cardiac involvement is rare (0.5%-2%), typically affecting the left ventricular wall. Arrhythmias and heart block may be uncommon presentations.
