cardiac papillary fibroelastoma
Pathology:
- fibroelastoma attached to the endocardium of a cardiac valve generally left-sided (case presentation [1] attachment to mitral valve)
- embolization may occur
- most are small (1.2 cm x 0.9 cm average)
Special laboratory:
- echocardiogram (may be incidental finding)
Differential diagnosis:
- atrial myxoma
- larger than papillary fibroelastoma
- generally associated with obstructive features
- 75% arise from fossa ovalis of left atrium, not a cardiac valve
- fever, weight loss may be noted [1]
- a tumor 'plop' may be heard on auscultation
