ICE imaging from the LA
Insertion of Carto Soundstar® into the LA and imaging the LAPW and esophagus were done in all patients without any complications. All of the present 73 study patients showed the esophagus location in the left side (i.e., posterior to the left PV antrum,Figure 1 ). The 3D ICE esophagus image showed a good overlap with the contrast esophagus image in all patients (Figure 3 ).
