Cardiac involvement in hydatid disease is more seldom than the involvement of the liver and the lungs. Cardiac cyst hydatid disease is diagnosed incidentally or by means of symptoms such as dyspnea and angina pectoris. Here, we present the case of a 45-year-old male patient who underwent open heart surgery for a randomly detected cardiac cyst hydatid during investigations carried out in a healthcare institution after accidentally falling from height. On the other hand, this patient did not have any complaints associated with hydatid disease before this event.
