RESUMO
Cardiac hydatid cyst is a rare parasitic disease. The purpose of this study was to describe the clinical, pathological features and the outcome of the surgical treatment of cardiac hydatid disease in our unit over a twenty-year period. METHODS: Between May 1994 and May 2014, seventeen cases of cardiac hydatid cysts were operated at our unit. Overall, twelve patients were male (mean age 25±13years). All patients were complaining of dyspnea and 71% presented with chest pain. The diagnosis, based on histological examination, was suspected on echocardiography and computed tomography of chest. RESULTS: Our study revealed five possible locations, which were in decreasing order of frequency: left ventricle, interventricular septum, right ventricle, left atrium and pulmonary artery. The surgical procedure was a controlled puncture and aspiration of the cyst content, with cystectomy (69%), or pericystectomy (31%). The resulting cavity left open in 6 cases (37.5%) or carefully closed in 10 (62.5%). Hospital mortality was 11.8% (n=2). Morbidity was marked by conduction abnormalities (n=2), bleeding and hematoma of the residual cavity that required surgical treatment (n=3). Eleven patients were followed with a mean period of 40.5±19.4 months. At follow-up, neither late deaths nor recurrence have occurred. CONCLUSION: Cardiac hydatid cyst is a serious disease whose treatment is surgical. Cystectomy and pericystectomy remain the two surgical techniques able to offer good chance of cure with acceptable morbidity and mortality.
