Coronary artery bypass in myocardial ischemia of the young due to hydatid cyst.

Cardiac hydatid cyst is an uncommon disease, especially in France. It is rarely responsible for myocardial ischemia, and even more rarely in the young. We report the clinical features and imaging of a 24-year-old Tunisian woman with hydatid cyst of the free wall of the left ventricle responsible for myocardial ischemia, associated with a hepatic hydatid cyst. Management consisted of a combination of surgery with cystopericystectomy and coronary artery bypass graft and prolonged medical treatment as for treatment of hepatic hydatid cyst. Three-year follow-up revealed no recurrence. This case illustrates two interesting points: the rare clinical presentation of cardiac hydatid cyst with a coronary syndrome in a young 24-year-old woman related to compression of the left anterior descending artery by the cyst with a need for coronary artery bypass graft after resection of the cyst, and the value of medical treatment of hydatid disease, even for cardiac localization.
