Preface

The first transesophageal echocardiogram (TOE/TEE) was performed in 1976 (M-mode only) and there were some who doubted that it would find a place in mainstream cardiac imaging. Over the last 30 years the technological advances in TEE have been exponential and have been reflected by its increasing utilization. Currently, almost all echocardiography labs will undertake TEE and the vast majority of valve operations are performed with TEE guidance. Those readers who have been exposed to TEE and other cardiac imaging modalities will know that the spatial and temporal resolution of transesophageal echocardiography is unsurpassed and that it is relatively easy to get good images with minimal training. The same readers will also be aware that, for these reasons, there are practitioners who bypass the appropriate training and use TEE as a very blunt diagnostic tool. The fact that transesophageal echocardiography can be used by such individuals is a travesty; I believe that performing a TEE study should be considered a privilege and with that privilege comes the responsibility of learning. The purpose of this book is to give practical guidance to those undertaking training in the art of transesophageal echocardiography. It is not an exhaustive text to be u
