Insights
Left ventricular myxoma is extremely rare in infants. This case highlights a successful surgical removal in a five-month-old, resolving severe outflow tract obstruction without recurrence.
Area of Science:
- Pediatric Cardiology
- Cardiac Surgery
- Pediatric Oncology
Background:
- Left ventricular (LV) myxomas are rare cardiac tumors.
- Myxomas in pediatric populations, especially infants, are exceptionally uncommon.
- Previous literature has not documented LV myxomas in infants.
Observation:
- A five-month-old infant presented with a large myxoma originating from the anterior, lateral, and superior aspects of the left ventricle.
- The tumor caused severe left ventricular outflow tract obstruction.
- Surgical access was achieved via the conal septum after right ventricular outflow tract opening.
Findings:
- The myxoma was successfully excised.
- The infant experienced transient complete heart block postoperatively.
- No tumor recurrence was observed at the nine-month follow-up.
Implications:
- This case demonstrates the feasibility of surgical intervention for LV myxomas in infants.
- Early diagnosis and surgical management are crucial for improving outcomes.
- Further research into the etiology and long-term prognosis of pediatric cardiac myxomas is warranted.
Abstract:
Left ventricular (LV) myxoma is particularly rare in children and has not been reported in infants. A five-month-old baby presented with a myxoma arising from the anterior, lateral, and superior aspect of the LV, causing severe left ventricular outflow tract obstruction. The LV was accessed through the conal septum after opening the right ventricular outflow. The child had transient complete heart block in the postoperative period. There was no recurrence of tumor at the nine-month follow-up.
