Surgical Management of Cardiac Hydatid Cyst and the Residual Intramural Ectocyst.

The cardiac hydatid cyst (HC) is a rare pathology and mostly is endemic in livestock raising countries. Patients do not have a specific presentation so it is mainly a diagnosis based on imaging. Finding HC anywhere in the body warrants looking for another hydatid in other organs. This is a case report of a young male who presented with nonspecific symptoms and during diagnostic workup, it happened that he has combined hepatic and cardiac HCs. The cardiac cyst was located intramurally in the interventricular septum and expanding down mostly to the left side of the diaphragmatic surface of the heart and partly crossing intramurally to the diaphragmatic surface of the right ventricle. Emergency open-heart surgery was performed; the endocyst was removed while intramural ectocyst was drained to prevent potential future residual space.
