Insights
A young girl with combined immunodeficiency syndrome underwent successful surgical repair for a left ventricular aneurysm. The procedure restored normal heart function and shape after bone marrow transplant engraftment.
Area of Science:
- Pediatric Cardiology
- Immunology
- Cardiovascular Surgery
Background:
- Combined immunodeficiency syndrome (CIS) can present with complex multisystemic manifestations.
- Left ventricular aneurysms are rare but serious cardiac complications, potentially leading to heart failure and thromboembolic events.
Observation:
- A 23-month-old girl with CIS developed a significant left ventricular aneurysm with an intramural thrombus.
- The patient's condition necessitated surgical intervention due to the aneurysm's size and thrombotic burden.
Findings:
- Surgical repair of the left ventricular aneurysm was successfully performed using endoventricular circular patch plasty (Dor procedure).
- The intervention was carried out post-bone marrow transplant engraftment, ensuring a stable immunological state.
- Postoperative assessment revealed excellent outcomes, with normalization of ventricular geometry and cardiac function.
Implications:
- This case highlights the feasibility and effectiveness of surgical correction for left ventricular aneurysms in pediatric patients with complex congenital conditions.
- The successful Dor procedure underscores the importance of a multidisciplinary approach in managing rare cardiovascular complications in immunocompromised children.
- Early detection and timely intervention can significantly improve long-term prognosis for pediatric patients with combined immunodeficiency syndrome and cardiac anomalies.
Abstract:
We describe the case of a 23-month-old girl with combined immunodeficiency syndrome and a left ventricular aneurysm. Due to the size of the aneurysm and development of an intramural thrombus, repair was performed after confirmation of bone marrow transplant engraftment. Endoventricular circular patch plasty (Dor procedure) was performed, with excellent outcome and normalization of ventricular geometry and function.
