Giant right atrial myxoma leading to cardiac arrest in an infant.

Abstract：

:We present the case of a three-month-old infant with a giant right atrial myxoma obstructing the tricuspid valve, who following haemodynamic deterioration and cardiac arrest, was operated upon as an emergency. On echocardiogram, there was a mass attached to the tricuspid annulus, in close proximity to the septal leaflet, with dimensions of 16.6 × 12.5 mm. The mass was prolapsing through the tricuspid valve into the right ventricle and obstructing the inflow. While preparing for surgery, cardiac arrest occurred, so the patient underwent an emergency operation under cardiopulmonary resuscitation. The mass was excised without damaging the tricuspid valve and the conduction system. Histologically, the mass consisted of a myxoid matrix with scatted globoid and star-shaped myxoma cells. The patient stayed 15 days in the intensive care unit and was discharged home on the 20th day postoperatively. Although accepted as a benign tumour, a myxoma can display an aggressive clinical course in infants. In centres where cardiac operations cannot be performed, these patients need to be transferred to cardiac centres as soon as possible. Whatever the clinical presentation, we advocate immediate surgical extirpation of the tumour in order to avoid any unpredictable consequences in its clinical course.
