Myocardial Cystic Hydatids Causing Cardiac Tamponade—Report of Cases

Abstract

Four patients with cystic hydatids located in pericardium and myocardium were admitted. Cardiac tamponade was determined in 1 of these cases. Surgical treatment was instituted for all cases. Transpericardial cardiac palpation was emphasized in cases where thoracotomy was necessary due to the lung cystic hydatids.

Hydatid Cyst on Right Ventricular Posterior Wall

“…Cardiac involvement in hydatidosis has been reported with a frequency in the range of 0.2% to 3%. [1][2][3][4][5] Cardiac hydatid cysts are more often seen in the left ventricle, presumably because blood flow is higher than in the right ventricle. [2][3][4][5] Signs and symptoms of such cysts are due to their location, growth, and rupture.…”

“…It has been suggested that anthelmintics (mebendazole or albendazole) should be given in the postoperative period because of the risks of vesicular implantation and embolization. [1][2][3][4] Although cardiac involvement of hydatid disease is rare even in endemic areas, this case study suggests that echocardiographic evaluation should be performed in patients with hydatid cysts elsewhere in the body. This useful workbook is dedicated to Bhagawan Sri Sathya Sai Baba who has been an inspiration in the treatment of patients in the Indian subcontinent.…”

“…1 –5 Cardiac hydatid cysts are more often seen in the left ventricle, presumably because blood flow is higher than in the right ventricle. 2 –5 Signs and symptoms of such cysts are due to their location, growth, and rupture. Disturbances of valvular function, ischemic events, and conduction anomalies may be caused by cystic pressure.…”

“…Cardiac involvement is seldom reported. 1 –5 A case is described of hydatid cyst located in the right ventricle, causing multiple pulmonary emboli.…”

Asymptomatic pericardial hydatid cyst

“…Hydatid cyst disease is endemic in sheep-raising countries, but cardiac involvement is rare, occurring in less than 2% of cases [1]. In Turkey, in a series of 600 pulmonary hydatid cysts, the heart was involved in only four patients [2]. When cardiac involvement occurs, it is mainly myocardial.…”
