Biatrial Myxoma Resembling an Interatrial Clot in Transit on Echocardiogram

A rare case of atrial myxoma with biatrial extension

“…Thrombi on echocardiogram may mimic myxomas and are difficult to distinguish especially when they are sessile unpedunculated masses with fringe like projections [9]. Most myxomas are solid tumors unlike in this patient which had myxomatous fringe like projections which could be seen floating in the atria on echocardiogram.…”

Biatrial Myxoma: A Case Report and Review of the Literature

“…A review by Peachell in 1998 reported approximately 19 cases of this tumor in the literature at that time 2 . Our review of the English literature revealed ten other entries in the literature since 1998 8–17 . These entries describe a total of ten patients with biatrial myxomas.…”

“…In the past, most were diagnosed using cardiac catheterization 13 . More recently, transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) have become the primary imaging modalities used 10,13,15,19 . TTE can be used to determine the size, mobility, shape, and location of the tumor.…”

“…2 Our review of the English literature revealed ten other entries in the literature since 1998. [8][9][10][11][12][13][14][15][16][17] These entries describe a total of ten patients with biatrial myxomas. This includes large multiyear retrospective reviews of single-center experiences, with the largest experience at any single institution consisting of one biatrial myxoma (Table 1).…”

“…13 More recently, transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) have become the primary imaging modalities used. 10,13,15,19 TTE can be used to determine the size, mobility, shape, and location of the tumor. However, it is less effective at identifying the site of attachment of the tumor.…”
