Tissue Doppler Velocity Imaging.
Echocardiographic assessment of Left Atrial Appendage function in patients with Mitral Stenosis by Tissue Doppler Velocity Imaging.
... Today Doppler transesophageal echocardiography is mostly used to assess the LAA function. LAAEV by PWD reflects the LAA function and the value of LAAEV < 25 cm is generally accepted as a LAA dysfunction. ...
