New World's old disease: cardiac hydatid disease and surgical principles.
Cardiovascular Journal of Africa 2017 September
BACKGROUND: Hydatid cyst is a parasitic disease caused by infection with the Echinococcus granulosus tapeworm larva. It is a major public health problem in endemic regions. Cardiac involvement of the disease is rare.
METHODS: Between 1985 and 2015, 12 patients were admitted to our clinic with a possible diagnosis of cardiac hydatid disease. Of these patients, six (50%) were male and six (50%) were female. Mean age of the patients was 42.6 years.
RESULTS: The most common location of cardiac hydatid disease was left sided (six patients, 50%). Five (41.7%) patients had cysts located in the right heart, whereas one (8.3%) had a cyst in the interventricular septum. Eleven (91.7%) of the patients were operated on via median sternotomy and the remaining one was operated on via a left anterolateral thoracotomy. Ten (83.3%) of the patients were operated on using cardiopulmonary bypass under moderate hypothermia, whereas the remaining two (16.7%) had off-pump surgery. There was no surgical mortality in our series. All patients were discharged with medical therapy (mebendazole or albendazole) for the duration of six months. No recurrences were observed in their follow ups.
CONCLUSION: Although cardiac hydatid disease is rare, its prevalence seems to have increased in the last decade. Any patient with suspected cardiac symptoms suggesting mass lesions should be considered for a differential diagnosis of cardiac hydatid disease, especially in developing countries. Definitive treatment is removal of the cyst, combined with medical therapy.
