Large calcified right atrial myxoma in a newborn. Rare cause of neonatal death.

Right atrial myxoma is a rare cause of heart failure in infancy and childhood. 1-4 Since its clinical diagnosis is elusive in this age group,4 it is usually not suspected in the differential diagnosis of cyanotic neonates with congestive cardiac failure. The implications, however, of making the diagnosis of this potentially curable tumour during life are obvious. We report a newborn baby with a calcified right atrial myxoma simulating cyanotic congenital heart disease.
