Isolated cardiac hydatid cyst presented as myopericarditis: A case report

Abstract

Hydatidosis commonly affect the liver and lungs but in rare cases, it can involve heart tissue. A 42-year-old man from urban areas of Khorasan Razavi province, northeastern Iran, was referred to the cardiac clinic with palpitation, and atypical chest pain in 2018. Large pericardial effusion, reduced left ventricle systolic function was found. A cystic-like lesion was also seen in inter-ventricular septum in echocardiography and high-resolution computed tomography (HRCT). Urgent cardiac surgery was done because of echocardiographic evidence of tamponade. Although the serologic analysis was negative for hydatidosis, surgical excision of cyst and the subsequent histopathological findings revealed a hydatid cyst. In endemic areas, hydatidosis should be considered in differential diagnosis of any cystic-like lesions, even if the serological analysis is negative.

Isolated cardiac hydatid cyst of the right ventricle

“…Although several agents have been used intraoperatively for protoscolicidal effect, such as iodine solution, cetrimide, ethanol, hypertonic saline, chlorhexidine, and methylene blue, the gold standard agent has not been identified [1,7,9,10]. There are publications that do not mention scolicidal impact during the operation [11]. According to the recommendation of the thoracic surgery clinic, which has more experience in hydatid cysts, with the risk that it might have reached the ventricle -we preferred 3% hypertonic saline solution.…”

“…According to the recommendation of the thoracic surgery clinic, which has more experience in hydatid cysts, with the risk that it might have reached the ventricle -we preferred 3% hypertonic saline solution. The area around the cyst required 3% NaCl impregnated gauze for Vakilian et al [11], removing the cyst directly. We aspirated and irrigated it with hypertonic saline.…”
