Intracardiac myxomas are most commonly found in the left atrium. The tumor is
typically pedunculated. The most common point of attachment is at the
atrial septum in the region of the fossa ovalis. Once the diagnosis is
made, the tumor is removed surgically. Follow up echocardiograms are
performed to rule out recurrence. The references below reflect the
different opinions on rate of recurrence.
The biplane image below displays the stalk and the
tissue characteristics of the myxoma.
