Background: Cardiac involvement is an uncommon presentation of hydatid disease. In this study, we aim to analyze the experience of surgical treatment of cardiac and great vessels echinococcosis in our cardiovascular and thoracic surgery department., Methods: Through a 16-year period, from 2000 to 2015, 27 patients underwent surgery for cardiac and great vessels hydatid disease. The clinical, operative, and postoperative data were analyzed through this retrospective and descriptive study., Results: Most of our patients came from a rural area. The most common symptom was chest pain. The diagnosis was mainly made by transthoracic echocardiography, which has shown the right ventricle as the most frequent location of the disease. All patients received surgical treatment under cardiopulmonary bypass, and only six surgeries were performed without cross-clamping the aorta. Inhospital mortality rate was 7.4%., Conclusions: Cardiac hydatidosis is a rare but potentially serious condition whose treatment is mainly surgical even for asymptomatic patients owing to its possible fatal complications. The surgery outcomes are usually satisfactory. Follow-up examinations are highly recommended to detect recurrences., (Copyright © 2020 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Cardiac hydatic cyst is a rare parasitic disease. We reported 45 patients with cardiac hydatid cysts; 33 of the 45 had a primitive, unique cardiac cyst. Altogether, 18 patients of our series were asymptomatic, and 27 patients complained of symptoms (dyspnea, chest pain, palpitations). In 11 cases the cyst was revealed by an acute complication; 3 of the 11 had pulmonary metastatic hydatidosis. The diagnosis was based on a series of test results in which hydatid serology and imaging (echocardiography, computed tomography, magnetic resonance imaging) played a predominant role. Cystopericystectomy is the gold standard procedure but is sometimes unsuitable for particular sites. In that case, a conservative approach (partial pericystectomy) is mandatory to preserve organ function. The operative mortality rate is 5.5%. Two pericardial recurrences were reported during follow-up.
