a·tri·al myx·o·ma

a primary cardiac neoplasm arising most commonly in the left atrium as a soft polypoid mucinous mass attached by a stalk to the atrial septum; it may resemble an organized mural thrombus. The symptoms may include cardiac murmurs, which change with alteration of body position and signs of mitral stenosis or insufficiency, with continuous danger of embolism by fragments of the tumor or its entire mass.

atrial myxoma

a benign, pedunculated, gelatinous tumor that originates in the interatrial septum of the heart. The tumor is characterized by palpitations, disseminated neuritis, nausea, weight loss, fatigue, dyspnea, fever, and occasional sudden loss of consciousness. It is treated by surgical removal of the tumor.
