Primary mitral valve sarcoma in infancy
1Department of Cardiovascular Surgery, National Kagawa Children's Hospital, Japan.
Insights
A rare primary mitral valve sarcoma in an infant was successfully treated with mitral valve replacement. The child remains disease-free 18 months post-operation without further therapy.
Area of Science:
- Pediatric oncology
- Cardiovascular surgery
- Rare tumors
Background:
- Primary cardiac sarcoma is exceptionally rare, particularly in pediatric patients.
- Left-sided heart tumors, especially sarcomas, pose significant diagnostic and therapeutic challenges.
Observation:
- A 7-month-old male infant presented with hemiparesis and a heart murmur.
- Diagnostic imaging revealed extensive primary mitral valve sarcoma.
- The infant underwent mitral valve replacement due to severe tumor invasion.
Findings:
- The infant tolerated mitral valve replacement well.
- Post-operative follow-up at 18 months shows no evidence of tumor recurrence.
- The patient remains free of cerebral metastasis and has not required adjuvant therapy.
Implications:
- This case highlights the feasibility of surgical intervention for primary mitral valve sarcoma in infants.
- Early diagnosis and aggressive surgical management can lead to favorable outcomes.
- Further research into pediatric cardiac sarcomas is warranted to optimize treatment strategies.
Abstract:
Primary cardiac sarcoma is a rare tumor, found especially in children, particularly in the left side of the heart. This report describes a rare case of primary mitral valve sarcoma in a 7-month-old male infant with hemiparesis and heart murmur who underwent mitral valve replacement because of excessive invasion of the mitral valve by the tumor. The patient remains well, free of recurrence and cerebral metastasis, and without adjuvant therapy 18 months after the operation.
