Three patients (75%) were male, one patient (25%) was female. Three cases (75%) had history of chest pain, 2 cases (50%) had palpitation, and one case (25%) had nausea, vomiting and fever. Echocardiography was the initial diagnostic test in 2 cases (50%), final diagnostic test in two cases (50%). In 3 cases (75%) the cyst was found in the left ventricle and one case (25%) in right ventricle. Median sternotomy was performed for all cases.ConclusionCardiac Hydatid cyst is a very rare disease.
