Abstract
OBJECTIVES: Cardiac cystic echinococcosis (CE), or hydatid cyst is exceptionally uncommon. We review the experience of surgical treatment of cardiac CE. METHODS: Twenty-six patients (11 females; mean age, 28.9 ± 7.6 years) with cardiac CE undergoing surgical treatment from February 1978 to April 2013 were reviewed. The operative methods mainly included puncture-aspiration cystectomy, intact endocyst enucleation and total cyst resection. RESULTS: Cardiac CE was located in the myocardium in 16 cases, pericardium in 8 and both myocardium and pericardium in 2. There were 21 cases with solitary hydatid cyst including at the left ventricle in 7, right ventricle in 5, right atrium in 2, interventricular septum in 1 and at the pericardium in 6; 5 cases were with multiple cysts. There was no operative mortality. All patients received albendazole postoperatively. The mean follow-up time was 68 ± 21 months (range 7-195 months) except for 4 who were lost to follow-up. There were three recurrences and one late death. CONCLUSIONS: Cardiac cystic echinococcosis (CE) remains a very infrequent zoonotic infection. Presenting symptoms of cardiac hydatid disease are variable depending on the size, number and location of the cyst. Echocardiography, corroborated with computed tomography or magnetic resonance imaging, affords the best diagnostic and follow-up confirmation. Surgical treatment is associated with a low morbidity and mortality, and the selection of proper technique is very important to completely remove the hydatid cyst and prevent recurrence. Postoperative oral antiparasitic therapy is necessary for a definitive cure.
