Summary
A rare cardiac myxoma in a teenager caused chest pain and palpitations. Surgical removal led to a full recovery with no signs of recurrence after 16 months.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Cardiac Surgery
Background:
- Cardiac myxomas are rare primary heart tumors, often presenting with obstructive or embolic symptoms.
- Teenage presentation of cardiac myxoma is uncommon, necessitating thorough diagnostic evaluation.
- Right ventricular outflow tract myxomas can mimic other conditions, requiring advanced imaging.
Observation:
- A 17-year-old female presented with palpitations and chest pain.
- Physical exam revealed a significant pulmonary systolic murmur.
- Diagnostic imaging showed pulmonary trunk dilatation, heart block, and a mobile mass in the right ventricular outflow tract.
Findings:
- Echocardiogram and cardiac catheterization confirmed a myxoma in the right ventricular outflow tract.
- Surgical resection was performed using extracorporeal circulation via right atrial access.
- Histopathological confirmation of myxoma post-excision.
Implications:
- Complete surgical excision of cardiac myxoma provides excellent long-term outcomes in adolescents.
- Early diagnosis and intervention are crucial for preventing complications.
- This case highlights the importance of considering cardiac tumors in young patients with cardiac symptoms.
