Summary
Cardiac rhabdomyomas in a newborn with tuberous sclerosis mimicked severe heart defects. These tumors obstructed blood flow, making surgical correction unlikely.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Medical Genetics
Background:
- Tuberous sclerosis is a genetic disorder that can cause benign tumors (hamartomas) to grow in various organs, including the heart.
- Cardiac rhabdomyomas are the most common primary cardiac tumors in infants and children, often associated with tuberous sclerosis.
Observation:
- A newborn presented with clinical signs suggestive of mitral atresia and hypoplastic left-heart syndrome.
- Diagnostic imaging and catheterization revealed multiple cardiac rhabdomyomas causing significant obstruction.
Findings:
- A left atrial rhabdomyoma completely obstructed the mitral valve orifice.
- Left ventricular rhabdomyomas caused severe subvalvular aortic stenosis, deemed unresectable.
Implications:
- This case highlights that cardiac rhabdomyomas can present as a diagnostic challenge, mimicking congenital heart defects.
- Early recognition of rhabdomyomas is crucial for appropriate management, even when surgical options are limited.
