[With permission of Shanewise et al. (3).]therefore, required in order to ensure a reliable assessmentof the LAA.Next, attention focuses on the aortic valve (AoV) alongwith the left ventricular outflow tract (LVOT) and proximalascending aorta. At 08 with either slight probe withdrawalor anteflexion, a long axis view of the LVOT andAoV is obtained (Fig. 4.6). This can also be obtainedfrom a four-chamber view at 08 while withdrawing theprobe to a higher esophageal position (as the AoV is asuperior structure in the heart anatomy), but care mustthen be taken to avoid leaving the optimal left transatrialimaging window. The orientation is gradually changed
