A rare case of intracardiac hydatid cyst in the interventricular septum of the heart

Hydatid disease, also known as cystic , occurs due to tapeworm. It is an endemic disease in certain livestock-raising countries. Cardiac involvement is seen rarely, in around 0.5% to 2% of patients with hydatid disease. Interventricular septum is involved in around 4% of cardiac cases. According to Yaman et al., cardiac is a rare condition with a prevalence ranging between 0.5 to 2 percent. Here we report a case of a hydatid cyst in the heart. A 57-year-old male patient came to Gowri Gopal hospital, Kurnool, Andhra Pradesh on 29 July 2023 with complaints of shortness of breath for 6 months. He also complained about pain in the chest region for 6 months.ECG findings include sinus tachycardia, probable left atrial enlargement, left ventricular hypertrophy, nonspecific T abnormalities and ST elevation. Chest X-ray PA View revealed left mild fibrosis. Echocardiography showed a hydatid cyst sized 3x2.8 cm., grade I diastolic dysfunction and trivial mitral regurgitation. The patient underwent surgical excision and mitral valve repair. He recovered and was discharged successfully. We conclude that surgical resection, washout of the cavity with saline solution, and albendazole treatment can produce excellent outcomes in interventricular cardiac hydatid cyst cases.
