Objective  To find out the best orientations and sections in diagnosing tetralogy of Fallot using multiplane transesophageal echocardiography (TEE).   Methods  The visible heart was compared with the images of multiplane TEE to determine the best orientations and sections in the multiplane TEE for tetralogy of Fallot.   Results  The best orientation and section of pulmonary artery and its branches in multiplane TEE was the pulmonary artery viewed at 0° from the upper part of esophagus; that of ventricular septal defect and aortic overriding were five chambers viewed at 0° from the middle part of esophagus or the left ventricle long-axis view at 135° from the middle and end parts of the esophagus; that of the right ventricular outflow tract stenosis and the right ventricular hypertrophy was the right ventricular outflow tract long-axis viewed at 45° from the middle part of esophagus.  Conclusion  The best orientations and sections in TEE based on the visible heart are helpful to simplify the operation procedure of multiplane TEE and to shorten the examination time.
