Cystic hydatid disease is responsible for the loss of 1 to 3 million disability-adjusted life years every year. Infestation of the heart, though rare, can result in serious complications if left untreated. We retrospectively collected information on 19 patients with cardiac hydatid cyst admitted at the Center for Cardiac Surgery of Ibn Al-Bitar Hospital in Baghdad from July 2007 to July 2011 who were either in need of a cardiac surgery for treating hydatid cysts or presented with emergency conditions. Nine (47%) patients presented with left-sided heart failure and mitral valve dysfunction, 5 (26%) patients had hydatid cysts in the pericardium, 3 (16%) patients had hydatid cyst in the right ventricle and presented with right-sided heart failure, and 2 (11%) patients who presented with cardiac arrhythmias had infestation in the interventricular septum. Removal of cysts following open-heart surgery was successful and was followed by the use of mebendazole or albendazole for 5 years. We conclude that cardiac hydatid cyst that leads to various cardiac symptoms can be successfully managed and should be considered as a diagnostic possibility in patients with cardiac symptoms in endemic areas.
