GONZALEZ L., Roberto et al. Cardiac hydatid disease: surgical treatment for recurrent hydatid cyst in the left ventricle. Rev. cir. [online]. 2019, vol.71, n.3, pp.266-269. ISSN 2452-4557.


Cardiac hydatid cyst is a rare disease caused by Echinococcus granulosus arrival of the coronary circulation.

Materials and Method:

52 years old man with a history of cardiac hydatid cyst operated 27 years ago, heart failure and coronary artery disease. He presented with a history of one year of progressive dyspnoea. Study with chest radiography, echocardiography and computed tomography showed an image compatible with cardiac hydatid disease recurrence in relation to the left ventricle, pulmonary artery and anterior descending artery. Ejection fraction of the left ventricle was approximately 30%. No evidence of extracardiac hydatid disease was found and surgical treatment was decided. Addressed by median sternotomy and extracorporeal circulation, a multiloculated myocardial hydatid cyst, with hundreds of daughter vesicles of different size was found. Pericystectomy of the hydatid cyst was performed without incident. The patient presented postoperative bleeding which required early reoperation. Posteriorly, was discharged without complications.


Hydatid disease is an endemic zoonosis in Chile. Heart location is infrecuent and correspond to 0.5 to 2% of the cases, usually associated with the presence of extracardiac cysts. The most common location is the free wall of the left ventricle at intramyocardial level. Medical treatment is often inadequate and surgical resection is recommended.
