Summary
This case study highlights a successful surgical resection of a cardiac rhabdomyoma in an infant. Echocardiography proved crucial for diagnosing this right ventricular tumor causing outlet obstruction.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Cardiac Surgery
Background:
- Rhabdomyomas are the most common primary cardiac tumors in infants and children.
- These benign tumors can lead to significant complications, including outflow tract obstruction.
Observation:
- A three-month-old infant presented with symptoms suggestive of cardiac obstruction.
- Echocardiography revealed a polypoid mass within the right ventricular cavity.
- The tumor prolapsed through the pulmonary valve during systole, causing significant outflow obstruction and a notable pressure gradient.
Findings:
- Diagnosis was confirmed via echocardiography, demonstrating a right ventricular rhabdomyoma causing pulmonary valve obstruction.
- Surgical resection of the cardiac rhabdomyoma was successfully performed.
- Microscopic examination confirmed the diagnosis of rhabdomyoma.
Implications:
- Echocardiography is essential for diagnosing cardiac rhabdomyomas, especially in infants with subtle cardiac murmurs.
- Early diagnosis and surgical intervention can lead to favorable outcomes.
- This case underscores the importance of advanced imaging in pediatric cardiac care.
