Discussion:
Various previous studies have demonstrated assessment of LAA area and
ejection fraction as well as transthoracic pulsed doppler
echocardiographic measurement of doppler flow velocities of the left
atrial appendage, a non-invasive method is useful for analysing LAA
function. Our study adds to this body of knowledge by demonstrating that
left atrial appendage wall velocity (LAAWV) obtained through TDE
echocardiography is a reliable and clinically relevant parameter for
analysing LAA functions..
