TTE showed left atrium with a linear, mobile, membrane-like structure (arrow) across left atrial appendage (asterisk) (A, B). TEE demonstrated a linear, mobile, membrane-like structure traversing the body of left atrial appendage without a turbulent Doppler color flow across the membrane with Color Doppler (C, D). (LA, left atrium; LV, left ventricle; LAA, left atrial appendage).

TTE on the parasternal long axis and apical 2 chamber views showed left atrium (LA) with a linear, mobile, membrane-like structure across the left atrial appendage (LAA) (Fig. 1A, B). Trans-esophageal echocardiogram (TEE) demonstrated a linear, mobile, membrane-like structure traversing the body of the LAA (Fig. 1C). A turbulent Doppler color flow jet with a mosaic pattern was not seen through a linear, mobile, membrane-like structure (Fig. 1D) and velocity step-up across the membrane was not observed in Pulsed-wave Doppler.
