===Benign Tumors of the Heart===
About 80% of primary tumors of the heart are benign.  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>.
===Malignant Tumors of the Heart===
About 20% of primary tumors of the heart are malignant in nature. 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.
===Tumors of the Heart Valves===
A subset of the primary tumors of the heart are tumors that involve the four heart valves, with equal distribution among the four heart valves.<ref name="Edwards-1953134"/>  The vast majority of these are papillary [[fibroelastomas]].  Primary tumors of the heart valves predominate in males and are generally benign.  Heart valve tumors often have symptoms related to the valve, such as [[stroke]] and [[TIA]], and infrequently [[sudden cardiac death]].

Overview

The primary tumors of the heart are tumors 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 from another part of the body, or infiltrate the heart via direct extension from the surrounding tissues.
