Transesophageal echocardiography (TEE) is one of the most significant developments in cardiology and cardiac imaging in the last decade. While monoplane TEE clearly showed the advantages of imaging from the esophagus, biplane TEE was the next important step forward. The combination of transverse and longitudinal axis images served to provide incremental information about various cardiac pathologies. Multiplane TEE is a further advancement that allows continuous visualization of cardiac anatomy by electronic or manual steering of the ultrasound beam through 180 degrees. The intermediate views obtained by beam steering provides an unlimited perspective of normal and abnormal cardiac anatomy. This ability to view cardiac structures in multiple planes aids the understanding of the spatial arrangement of normal cardiac structures and complex disorders of cardiac anatomy. Multiplane TEE technology also eases the examination by reducing the need for probe manipulation. The ability to obtain multiplane images in a sequential manner lays the foundation for three-dimensional imaging of the heart. Ongoing developments in transducer technology should further strengthen the clinical role of TEE.
经食管超声心动图（TEE）是过去十年中心脏病学和心脏成像领域最重要的进展之一。虽然单平面TEE清楚地显示了从食管成像的优势，但双平面TEE是向前迈出的下一个重要步骤。横轴和纵轴图像的结合有助于提供有关各种心脏病变的更多信息。多平面TEE是进一步的进步，它允许通过超声束的电子或手动操纵在180度范围内连续观察心脏解剖结构。通过波束控制获得的中间视图提供了正常和异常心脏解剖结构的无限视角。这种在多个平面上观察心脏结构的能力有助于理解正常心脏结构的空间排列以及心脏解剖结构的复杂紊乱。多平面TEE技术还通过减少探头操作的需要简化了检查。以连续方式获取多平面图像的能力为心脏的三维成像奠定了基础。换能器技术的不断发展应进一步加强TEE的临床作用。
