Atrial fibrillation is associated with low-flow state and increased
thrombogenicity in the left atrium (LA). Multiple echocardiographic
presentations, including thrombosis, sludge, and smoke formation, have
been demonstrated in just one biplane transesophageal echocardiographic
view, along with normal structures, i.e., pectinate muscles and Coumadin
ridge, which are highly educational for cardiologists.
