A 48-year-old woman with episodic syncope has echocardiographic evidence of a mass in the left atrium. The following is/are true statement(s):

c. If this is a myxoma attached to the atrial septum, the adjacent septum should be removed with it

e. The most common primary malignant tumor of the heart is angiosarcoma

Primary cardiac tumors commonly arise in the left atrium and can present with dyspnea, syncope, congestive failure and systemic embolism. Transseptal puncture should not be used for diagnosis because of the risk of embolism. Most primary cardiac tumors are benign by a 3:1 ratio. The most common malignant tumor is the angiosarcoma. Myxoma is the most common benign tumor, but it can recur and the adjacent atrial septum should be resected with it. In infancy, the most common cardiac tumor is a rhabdomyoma.
