A prospective comparison of the multiplane probe with the biplane probe in structure visualization and Doppler examination during transesophageal echocardiography . To compare the imaging capability of the multiplane probe with that of the biplane probe , 317 consecutive patients were randomized to undergo transesophageal echocardiography with either probe . Images of 24 cardiac structures and nine Doppler signals were graded prospectively on a three-grade system . Both multiplane and biplane probes provided excellent visualization of cardiac structures and Doppler signals , but the multiplane probe was significantly superior to the biplane probe . There were no differences in the number of attempts at esophageal intubation , the amount of sedation used , and the examination time . The number of complications was similar , although all failed intubations occurred with the multiplane probe .
