Insights
A rare cardiac hydatid cyst in the interventricular septum was surgically removed from a 54-year-old female. This exceptional case highlights successful treatment of a rare heart cyst compressing cardiac function.
Area of Science:
- Cardiology
- Parasitology
- Surgical Pathology
Background:
- Cardiac hydatid cyst is a rare parasitic infection caused by Echinococcus granulosus.
- Cysts in the interventricular septum are exceptionally uncommon, posing diagnostic and surgical challenges.
Observation:
- A 54-year-old female presented with chest pain, dyspnea, and malaise.
- Transthoracic echocardiography revealed a large cystic mass (50 × 59 mm) in the interventricular septum, compressing both ventricles and protruding to the right ventricular epicardium.
Findings:
- Surgical excision of the cardiac hydatid cyst was successfully performed.
- The patient recovered without symptoms and was discharged on the 8th postoperative day.
Implications:
- This case underscores the importance of considering rare parasitic infections in cardiac masses.
- Successful surgical management of interventricular septal hydatid cysts is feasible, even with significant cardiac compression.
Abstract:
Cardiac hydatid cyst is a rare condition, and the location of a hydatid cyst in the interventricular septum is exceptional. A 54-year-old female was admitted to our hospital with complaints of chest pain, shortness of breath and malaise. Transthoracic echocardiography defined a cystic mass lesion of 50 × 59 mm originating from apex of the heart protruding into and compressing the interventricular septum. The cyst was excised surgically and the patient was discharged on the 8th postoperative day without symptoms. In our case, localization of the cystic mass was within interventricular septum which is an uncommon site. It limited both ventricular volumes significantly. In addition, this cyst was extensively protruding to the right ventricular epicardium.
