Abstract :
We describe the clinical and echocardiographic features in 12 patients with hydatid cyst of the heart who were screened between 1985 and 2001. Presenting symptoms have a wide variability but the main symptom was precordial pain. The electrocardiogram was always abnormal and showed T wave inversion in 8 cases, ST depression in 5 cases, incomplete right bundle-branch block in one case and atrial fibrillation in one case. Transthoracic echocardiography and transoesophageal echocardiography constitute the imaging procedure of choice for the diagnosis of cardiac hydatid cyst with a high sensibility, specificity. Computed tomography (CT) was performed in all patients and confirmed the echocardiographic data. MRI was performed in one patient with right atrium hydatid cyst location and confirmed the echocardiographic data.

Conclusion — In the presence of atypical symptomatology in a patient coming from an endemic area of hydatid cyst, the diagnosis of cardiac echinococcosis is possible. TTE and TEE are the imaging procedure of choice and sufficient for the diagnosis of cardiac hydatid cyst. CT and/or MRI provide more information about the extension of echinococcus disease in other intra- or extrathoracic locations.
