This case report documents a rare association between tricuspid hemangioma and hypoplastic left heart syndrome in an infant presenting with sudden infant death syndrome.
May warrant considering hemangioma in pediatric HLHS differentials; leaves open need for larger series on tumor associations.
Primary cardiac tumors are rare in children with a low incidence varying from 0.0017 to 0.28% in autopsy studies. Approximately 90% of the reported primary cardiac tumors in the pediatric population are benign and the most common subtype is rhabdomyomas accounting for approximately 60%, while hemangiomas are rare primary tumors with a 5% incidence. Hypoplastic left heart syndrome is abnormal development of the left-sided cardiac structures, leading to obstruction of blood flow from the left ventricle out-flow tract. Here we report a case of tricuspid hemangioma in association with hypoplastic left heart syndrome, a rare association not previously reported in the literature.
