Cardiac rhabdomyoma simulating pulmonic stenosis
Catheterization and Cardiovascular Diagnosis
|January 1, 1979
Summary
A pedunculated rhabdomyoma in the right ventricle prolapsing through the pulmonic valve mimicked tetralogy of Fallot spells. Surgical excision resolved the tumor and associated symptoms.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Cardiac Surgery
Background:
- Right ventricular tumors are rare cardiac masses.
- Pedunculated rhabdomyomas can cause significant hemodynamic compromise.
- Mimicking congenital heart disease poses diagnostic challenges.
Observation:
- Echocardiography revealed a dense echo mass within the pulmonic valve during systole.
- Angiography confirmed a pedunculated mass originating from the right ventricle.
- The mass prolapsed through the pulmonic valve, simulating tetralogy of Fallot spells.
Findings:
- A right ventricular pedunculated rhabdomyoma was identified as the cause of the symptoms.
- The tumor's prolapse through the pulmonic valve led to the misdiagnosis.
- Surgical excision of the rhabdomyoma was successfully performed.
Implications:
- This case highlights the importance of comprehensive diagnostic evaluation for complex cardiac presentations.
- Early and accurate diagnosis of cardiac tumors is crucial for appropriate management.
- Surgical intervention can effectively treat symptomatic cardiac rhabdomyomas.
