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..
