Insights
A rare cardiac myxoma in the right ventricle of an 11-year-old child caused pulmonary obstruction. Surgical removal was successful, with no recurrence after 18 months.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Cardiac Surgery
Background:
- Cardiac myxomas are typically found in the left atrium.
- Right ventricular myxomas are rare and can lead to pulmonary embolism or obstruction.
- Tumors obstructing the pulmonary orifice pose a significant risk, especially in children.
Abstract:
The right ventricle is an uncommon location for cardiac myxoma. Its most common complications are pulmonary embolism and obstruction due to pulmonary valve tumor. We report the case of a 11-year old child with repetitive syncopes admitted to Cardiology ward. Echocardiography showed a right ventricular myxoma of 2cm obstructing the pulmonary orifice. Emergency surgical excision was performed under cardiopulmonary bypasss with favorable postoperative course. Anatomo-pathological examination of the surgical specimen confirmed the diagnosis of myxoma. At 18 months follow-up, there was no evidence of tumor recurrence.
