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]
Myxoma is a rare, benign stromal tumor of mesenchymal origin often confused with other conjunctival stromal tumors. Conjunctival myxomas are thought to originate in Tenon's capsule and can masquerade as conjunctival lymphoma, lymphangioma, ocular surface squamous neoplasia (OSSN), or amelanotic melanoma.

The tumor may break apart and can embolize. Embolization can be systemic or pulmonic. Tumors with the highest anatomic risk for embolization are located in the left atrium or aortic valve. Some tumors produce no symptoms and are incidentally found. [7] Systemic symptoms [8] Primary cardiac tumors may secrete factors including interleukin-6 and ...
The LAMB acronym refers to lentigines, atrial myxomas, and blue nevi. [1] NAME refers to nevi, atrial myxoma, myxoid neurofibromas, and ephelides. [1] Testicular cancer, particularly Sertoli cell type, is associated with Carney syndrome. [7] Thyroid and pancreas cancer may also occur. [8] [9]
Isolated TS are often associated with carcinoid disease and right atrial myxoma. Mid-diastolic Atrial myxoma: Atrial myxomas are benign tumors of the heart. Left myxomas are far more common than right myxomas and those may cause obstruction of the mitral valve producing a mid-diastolic murmur similar to that of mitral stenosis. Mid-diastolic
Turbulent flow causes dephasing and signal loss allowing valvular disease to be qualitatively appreciated. The left ventricular short axis cines are acquired from base to apex and are used for quantifying end-diastolic and end-systolic volumes, as well as myocardial mass. Tagging sequences excite a grid pattern that deforms with cardiac ...

Left atrial enlargement can be mild, moderate or severe depending on the extent of the underlying condition. Although other factors may contribute, left atrium size has been found to be a predictor of mortality due to both cardiovascular issues as well as all-cause mortality.
