Longitudinal transgastric echocardiographic views utilizing a single-plane probe: anatomic correlations and clinical applications.
In order to widen the diagnostic capability of single-plane transesophageal echocardiography, which has been so far confined to transverse imaging planes, we obtained four transgastric longitudinal echocardiographic views which have not been previously described. These views can image structures such as superior and inferior vena cava, the right ventricular inflow and outflow tract, the mitral apparatus and the ascending aorta, which are poorly visualized by transesophageal transverse single-plane echocardiography. Among 400 consecutive patients these scans gave relevant additional diagnostic information in 62 cases (15.5%) and provided the correct diagnosis in 37 (9.2%). There were no complications related to the longer gastric manipulation of the probe and the quality of the images was high. We conclude that longitudinal echotomographic scanning of the heart is not exclusively confined to the use of biplane or omniplane probes, but longitudinal views can be consistently obtained with a single-plane instrument.
