Key result
A large calcified right atrial myxoma obstructing the tricuspid valve caused severe cyanosis, congestive cardiac failure, and death in a newborn within 10 hours of birth.
Right atrial myxoma is a rare but potential cause of severe cyanosis, heart failure, and neonatal death.
Right atrial myxoma warrants consideration in neonatal cyanosis and heart failure differentials; hypothesis-generating.
A newborn baby girl presented at birth with severe cyanosis, congestive cardiac failure, and an ischaemic leg ulcer, and died within 10 hours of birth. Necropsy disclosed a large haemor- rhagic, calcified right atrial myxoma obstructing the tricuspid valve.
