Hydatid Cyst of Heart and Mediastinum: Report of Three Cases

We describe three cases of hydatid cyst of the heart. The first patient was a 46-year-old man who was found to have a systolic murmur on routine physical examination and echocardiography showed an interventricular cyst. He was operated on and recovered uneventfully. The second patient was a 55-year-old woman with a hydatid cyst of the interventricular septum, which was diagnosed by echocardiography. The cyst was resected surgically. She developed complete heart block after surgery, which was managed by an epicardial pacemaker. The third patient was a 15-year-old girl who was diagnosed with a large hydatid cyst of the left ventricle by echocardiography, but during the operation in addition to the left ventricular cyst a mediastinal cyst was found in the left side of the inferior vena cava. Both cysts were resected surgically and the patient recovered without any complication (Iranian Heart Journal 2006; 7 (3):52-55).
