A Large Cardiac Papillary Fibroelastoma Arising from the Coumadin Ridge: Unusual Location and Presentation

Abstract

HighlightsThe coumadin ridge is a very unusual location for a cardiac PFE.Although benign, large, mobile cardiac PFEs can pose a significant embolic risk.Multimodality CV imaging can differentiate cardiac PFE from other cardiac tumors.

Prominent para‐cardiac fat mimicking left atrial appendage thrombus on echocardiography: Utility of cardiac computed tomography

“…[4][5][6] Mimics of LAA thrombus are uncommon, with the most frequent being artefact (generally from a prominent Coumadin ridge). [7][8][9][10][11] Less common mimics include tumors, such as papillary fibroelastoma, 6 and anatomic variants such as prominent, thickened pectinate muscles, and transverse sinus pericardial reflections. [8][9][10] However, in this case, this focal echodensity represents an unusual prominent fat deposit below the limbus mimicking thrombus.…”

“…3 TEE is considered the primary imaging modality for exclusion of LAA thrombus. [4][5][6] Mimics of LAA thrombus are uncommon, with the most frequent being artefact (generally from a prominent Coumadin ridge). [7][8][9][10][11] Less common mimics include tumors, such as papillary fibroelastoma, 6 and anatomic variants such as prominent, thickened pectinate muscles, and transverse sinus pericardial reflections.…”

“…In patients with nonvalvular AF, LAA is the most common site for intra‐cardiac thrombus formation due to blood flow stasis and contractile dysfunction 3 . TEE is considered the primary imaging modality for exclusion of LAA thrombus 4–6 . Mimics of LAA thrombus are uncommon, with the most frequent being artefact (generally from a prominent Coumadin ridge) 7‐11 .…”
