Myxomas are the most common primary cardiac tumor. It is estimated that more than 75% of myxomas originate in the left atrium either at the mitral annulus or the fossa ovalis border of the interatrial septum; 20% arise from the right atrium while 5% stem from both atria and the ventricle. Atrial myxomas are associated with a triad of complications, including obstruction, emboli, and constitutional symptoms (such as fever, weight loss).
