Obstructive right ventricular outflow tract hemangioma in an adolescent

Area of Science:

• Cardiovascular Surgery
• Pediatric Oncology
• Diagnostic Imaging

Background:

• Cardiac tumors are uncommon in pediatric populations, with rhabdomyomas being most frequent.
• Cardiac hemangiomas represent a small fraction (2.8%) of primary cardiac tumors, with limited reported cases.
• Advancements in imaging enhance the diagnosis of pediatric cardiac masses.

Observation:

• A case of cardiac hemangioma in the right ventricular outflow tract of an adolescent patient is presented.
• The tumor caused moderate to severe obstruction of blood flow.
• This specific location and presentation are unusual for cardiac hemangiomas.

Findings:

• Successful surgical resection of the cardiac hemangioma was achieved.
• The adolescent patient experienced relief from the obstructive symptoms post-surgery.
• This case adds to the limited literature on cardiac hemangiomas, particularly in the pediatric age group.

Implications:

• Highlights the importance of considering rare cardiac tumors like hemangiomas in pediatric patients with obstructive symptoms.
• Demonstrates the feasibility and success of surgical intervention for right ventricular outflow tract hemangiomas.
• Emphasizes the role of accurate diagnostic imaging in identifying and characterizing these rare pediatric cardiac neoplasms.
