Echocardiography for left atrial appendage structure and function
Color tissue velocity imaging (A) and strain imaging for the assessment of left atrial appendage (LAA) function. On tissue velocity imaging, positive waves (toward the transducer) corresponding to the LAA emptying are seen during diastole and negative wave (due to LAA filling) is seen …
