==Overview==


The '''primary tumors of the heart''' are [[tumor]]s that arise from the normal tissues that make up the [[heart]].  This is in contrast to secondary tumors of the heart, which are typically either [[metastatic cancer|metastatic]] from another part of the body, or infiltrate the heart via direct extension from the surrounding tissues.

__NOTOC__


The most common primary tumor of the heart is the [[myxoma]].  In surgical series, the myxoma makes up as much as 77% of all primary tumors of the heart.<ref name="MolinaEdwards">{{cite journal | author=Molina JE, Edwards JE, Ward HB | title=Primary cardiac tumors: Experience at the University of Minnesota | journal=Thorac Cardiovasc Surg | year=1990 | pages=183-91 | volume=38 Suppl 2| id=PMID 2237900}}</ref>  Other benign tumors of the heart include [[rhabdomyoma]]s, [[fibroma]]s, [[hemangioma]]s, [[lipoma]]s, [[paraganglioma]]s, myocytic hamartomas, and [[papillary fibroelastoma]]s<ref name="Edwards-1953134">{{cite journal | author=Edwards FH, Hale D, Cohen A, Thompson L, Pezzella AT, Virmani R. | title=Primary cardiac valve tumors | journal=Ann Thorac Surg | year=1991 | volume=52 | issue=5 | pages=1127-31 | id=PMID 1953134}}</ref>.
==[[Cardiac tumors historical perspective|Historical Perspective]]==


About 20 percent of primary tumors of the heart are malignant in nature.<ref name="MolinaEdwards"/>  Malignant tumors of the heart include [[rhabdomyosarcoma]]s, [[angiosarcoma]]s, myxosarcomas, [[fibrosarcoma]]s, [[leiomyosarcoma]]s, reticulum cell sarcomas, and [[liposarcoma]]s.  The cardiac sarcomas may occur at any age, but are more commonly seen in individuals in their 20s to 40s.  They occur equally in males and females.

A subset of the primary tumors of the heart are tumors that are found on the valves of the heart.  Tumors that affect the valves of the heart are found in an equal distribution among the four heart valves.<ref name="Edwards-1953134"/>  The vast majority of these are papillary fibroelastomas.  Primary tumors of the valves of the heart are more likely to occur in males.  While most primary tumors of the valves of the heart are not malignant, they are more likely to have symptoms related to the valve, including neurologic symptoms and (in a few cases) [[sudden cardiac death]].

=== Secondary (metastatic) Malignant Tumors of the Heart===
 
*20 to 40x more common than primary cardiac tumors
*typically carcinomas, melanomas, and leukemias/lymphomas
*discrete tumors found in 10 to 12% of all autopsies
:*any involvement of heart by a malignancy found in 20% of all autopsies
'''Pericardium'''
:*frequently bloody effusion containing tumor cells
:*tamponade
:*may also cause constriction from tumor infiltration of pericardial sac
 
==Pathophysiology==
 
:*Emboli into coronary arteries
:*Retrograde flow through cardiac lymphatics
:*Direct extension from mediastinum
:*Emboli or spread via great veins => endocardial metastases
::*[[Hypernephroma]]
::*Testicular sarcoma
::*IVC [[leiomyosarcoma]]

Replacement of electrically active tissue by inert tissue such as a tumor or [[Chagas disease]] can result in Q waves. Pericardial [[metastases]] can result in [[atrial fibrillation]] or [[atrial flutter]].

== Prognosis ==
 
The vast majority of the tumors of the heart have a benign course and are not directly fatal.  However, even the benign tumors of the heart can be lethal due to either direct extension into the electrical conduction system of the heart (causing [[third degree AV block|complete heart block]] or a fatal dysrhythmia), or due to [[embolism|emboli]] from the tumor mass that may have lethal sequelae.
 
The malignant tumors of the heart have a worse prognosis.  Cardiac sarcomas generally lead to death within 2 years of diagnosis, due to rapid infiltration of the myocardium of the heart and obstruction of the normal flow of blood within the heart.<ref name="Burke-Sarcoma">{{cite journal | author=Burke AP, Cowan D, Virmani R | title=Primary sarcomas of the heart | journal=Cancer | year=1992 | volume=69 | issue=2 | pages=387-95 | id=PMID 1728367}}</ref><ref name="Burke-Osteosarcoma">{{cite journal | author=Burke AP, Virmani R | title=Osteosarcomas of the heart | journal=Am J Surg Pathol | year=1991 | volume=15 | issue=3 | pages=289-95 | id=PMID 1705103}}</ref>
