Obstructive neonatal atrial myxoma.

Area of Science:

• Pediatric Cardiology
• Cardiac Oncology

Background:

• Cardiac myxoma is the most common primary cardiac tumor in adults, but rare in neonates.
• Myxomas are endocardial masses, often attached to the interatrial septum, commonly in the left atrium.
• Understanding pediatric cardiac tumors is crucial as their types and epidemiology differ from adults.

Purpose of the Study:

• To report a rare case of neonatal cardiac myxoma.
• To highlight the successful surgical management of this rare condition.

Main Methods:

• Case report of a neonatal cardiac myxoma.
• Surgical excision of the tumor.

Main Results:

• A rare neonatal cardiac myxoma arising from the interatrial septum was identified.
• The myxoma caused significant mechanical obstruction of blood flow through the tricuspid valve.
• Successful surgical excision resulted in an uneventful recovery.

Conclusions:

• Large neonatal myxoma is exceptionally rare.
• Surgical excision in the first day of life is infrequent.
• Early recognition and management of pediatric cardiac tumors are vital.
