Summary
A large, unresectable right ventricular rhabdomyoma was surgically palliated with valve closure and atrial-pulmonary artery anastomosis. The patient remains asymptomatic seven years post-operation with no tumor growth.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Pediatric Oncology
Background:
- Right ventricular tumors are rare and can present significant surgical challenges.
- Intracavitary tumors involving critical structures like the interventricular septum and tricuspid valve are often deemed nonresectable.
Observation:
- A 24-year-old patient presented with a large intracavitary right ventricular tumor.
- The tumor involved the interventricular septum, free ventricular walls, and tricuspid valve, rendering it nonresectable.
Findings:
- Surgical palliation involved tricuspid and pulmonary valve closure.
- The right atrium was anastomosed to the pulmonary artery bifurcation.
- The patient has remained asymptomatic for seven years post-surgery.
Implications:
- This case demonstrates a successful palliative surgical approach for a nonresectable intracavitary right ventricular tumor.
- Long-term follow-up shows stability of the rhabdomyoma without progression.
- Palliative strategies can offer significant long-term benefits in complex cardiovascular tumor cases.
