Most heart tumors begin with myxomas, fibromas, rhabdomyomas, and hamartomas, although malignant sarcomas (such as angiosarcoma or cardiac sarcoma) have been known to occur. In a study of 12,487 autopsies performed in Hong Kong seven cardiac tumors were found, most of which were benign. [ 1 ]
A myxoma is a rare benign tumor of the heart. Myxomata are the most common primary cardiac tumor in adults, and are most commonly found within the left atrium near the valve of the fossa ovalis. Myxoma may also develop in the other heart chambers. [1] The tumor is derived from multipotent mesenchymal cells. [1]
Thromboembolic symptoms: lung and systemic thromboembolic condition resulting from the tumor. [5] Symptoms caused by primary cardiac tumors are usually dependent on size and location. Cardiac tumors can cause a variety of symptoms. The mass size can obstruct blood flow or interfere with cardiac valve function and produce symptoms of heart failure.
Signs and symptoms in cardiac fibroma are nonspecific, some individuals experience arrhythmias, dyspnea, cyanosis, chest-pain and sudden mortality. [1] In addition, the majority of individuals with cardiac fibroma are asymptomatic therefore leading to signs and symptoms that depend on the size and location of the tumor. [4]
