Insights
A rare heart hydatid cyst caused severe breathing problems in a 35-year-old woman. The cyst, located in the pericardial oblique sinus, blocked pulmonary veins, leading to significant shortness of breath.
Area of Science:
- Cardiology
- Parasitology
- Radiology
Background:
- Hydatidosis is a parasitic infection caused by Echinococcus granulosus.
- Cardiac involvement in hydatidosis is rare, with most cases occurring in the liver or lungs.
- Pericardial hydatid cysts are exceptionally uncommon.
Observation:
- A 35-year-old female presented with progressive dyspnea and severe orthopnea.
- Imaging revealed a pericardial hydatid cyst in the oblique sinus.
- The cyst extended to the left atrium's posterior wall, obstructing all pulmonary vein ostia.
Findings:
- The case highlights an unusual cardiac manifestation of hydatidosis.
- The cyst's location and extension caused significant pulmonary venous obstruction.
- Surgical intervention was necessary to manage the life-threatening condition.
Implications:
- This case underscores the importance of considering rare diagnoses in patients with unexplained cardiorespiratory symptoms.
- Early diagnosis and prompt surgical management are crucial for favorable outcomes in cardiac hydatidosis.
- Further research into the prevalence and management of cardiac hydatid cysts is warranted.
Abstract:
Hydatid cyst of the heart is an uncommon presentation of hydatidosis. We present a case of pericardial hydatid cyst in pericardial oblique sinus with extension to posterior wall of left atrium (LA), occluding all pulmonary vein ostia in a 35 year-old female with progressive dyspnea and severe orthopnea.

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
