Overview
Pathophysiology
Papillary fibroelastoma
- Primary tumor of the heart that typically involves one of the valves of the heart
- Papillary fibroelastoma is generally considered benign, and represents 10% of all primary tumors of the heart
- Papillary fibroelastoma are the third most common type of primary tumor of the heart, behind cardiac myxomas and cardiac fibromas.[1]
- The pathogenesis of papillary fibroelastoma is characterised by the mechanical effects of the tumor and the transient occlusion of the left main coronary artery (by the tumor), while a heart attack or sudden cardiac death may be due to embolisation of a portion of the tumor into a coronary artery.[2]

-
HEART: Metastatic Tumor: Gross very unusual large metastatic carcinoid in right atrium
-
Cardiac Myxoma A gelatinous tumor is attached by a narrow pedicle to the atrial septum. The myxoma has an irregular surface and nearly fills the left atrium.
-
Cardiac Myxoma There was a calcified right atrial mass on the X ray of a 47-year-old man. Resection demonstrated a smooth-surfaced tumor. The gritty material seen microscopically on cut section was calcified and ossified myxoma.
-
Cardiac Fibroma Cut surface of the tumor shown in figure 6-2. The left ventricular (LV) cavity is present behind the mass. The patient was a 4-month-old child who died suddenly without a previous medical history.
-
This tumor was resected from the right atrium of a 1-year-old boy with pericardial effusions. Note areas of hemorrhage and dilated vessels. The patient was well 49 months postoperatively.
-
Papillary fibroelastomas are often on the arterial surface and may project into the coronary ostium, causing ostial occlusion. This tumor is in the noncoronary sinus.
