Obstructive neonatal atrial myxoma

Introduction Cardiac myxoma is a benign neoplasm representing the most common primary cardiac tumor in adults, however it is unusual in neonates. It is represented by an endocardial mass that occupies the cardiac chamber. Although the majority of myxomas are attached to the fossa ovalis of the interatrial septum, they also attach to the walls of the cardiac chambers and to valve leaflets surfaces. Approximately 75% of myxomas are found in the left atrium, 20% are located in the right atrium, and rarely in the ventricles. Presentation of case We describe a rare case of neonatal cardiac myxoma arising from interatrial septum, causing significant mechanical obstruction to blood flow through tricuspid valve, in an otherwise normal newborn. The patient underwent successful excision of the myxoma with an uneventful recovery [1]. Discussion Cardiac tumors are rare in children, thus an understanding of the common types of benign and malignant paediatric cardiac tumors and their imaging features, is important because the epidemiology and tumor types differ from those encountered in adults. Conclusion Large neonatal myxoma is exceptionally rare and even more infrequent is the surgical excision in the first day of life.
