Recurrent Left Atrial Myxoma in a Young Patient: A Rare Entity

Abstract

Recurrence of atrial myxoma arising from the site other than inter-atrial septum is quite rare, which is more common in familial than sporadic cases. We here in present a case of 15-year-old young female who presented with recurrence of left atrial (LA) myxoma from unusual site - posterior LA wall after 3 years without any constitutional symptoms, which is the hallmark of recurrence. Complete removal of underlying atrial septum with atrial wall for recurrence prevention is the dictum in primary operation for tumour removal.
