Question Answer
What is the likelihood that cardiac neoplasm is metastatic?Metastases from other primary tumors are more common (75% of cardiac neoplasms) . Sites of these primary tumors include the lung, breast, skin, kidney, lymphomas, and Kaposi's sarcoma in patients with AIDS.
What is the most common cardiac neoplasm?An atrial myxoma is a benign gelatinous growth, usually pedunculated and usually
arising from the interatrial septum of the heart in the region of the fossa ovalis. It is
the most common primary cardiac neoplasm.
Are atrial myxomas malignant?Although benign, atrial myxomas can embolize, leading to metastatic disease, or can
cause relative valvular dysfunction.
What is the inheritance pattern of atrial myxoma?The majority of myxomas are sporadic, but autosomal-dominant transmission has
been noted.
What are the signs and symptoms of atrial myxoma?Prototypically present with fatigue, fever, syncope, palpitations, malaise, and a lowpitched
diastolic murmur that changes character with changing body positions (diastolic
plop)
