Simultaneous hydatid cysts of both the right atrium and right ventricle

Area of Science:

• Cardiology
• Parasitology
• Surgical Innovation

Background:

• Hydatid disease, caused by Echinococcus granulosus, typically affects the liver but can manifest in cardiac chambers, a rare occurrence.
• Cardiac echinococcosis poses significant risks, including embolic events and sudden death, necessitating accurate diagnosis and timely intervention.

Observation:

• A 77-year-old male with a history of hepatic hydatid cyst surgery presented with a transient ischemic attack.
• Incidental diagnosis of mobile right atrial and right ventricular hydatid cysts during etiological workup.
• Transthoracic echocardiography proved highly effective for initial diagnosis.

Findings:

• Transesophageal echocardiography and computed tomography confirmed the presence of both right atrial and right ventricular hydatid cysts.
• Surgical excision of both cardiac hydatid cysts was successfully performed under cardiopulmonary bypass.

Implications:

• This case highlights the importance of considering cardiac involvement in hydatid disease, even after hepatic surgery.
• Successful surgical removal under cardiopulmonary bypass demonstrates a viable strategy to prevent severe complications from cardiac hydatidosis.
• Early and accurate diagnosis using advanced imaging modalities is crucial for managing this rare but dangerous condition.
