Clinical Manual and Review of Transesophageal Echocardiography, Second Edition  is a comprehensive text with multiple images and in-depth discussions of the application of transesophageal echocardiography (TEE) in a variety of clinical scenarios inside and outside the operating room. This book's intended audience is not limited to the field of anesthesia. As mentioned in the preface, this book is also an excellent source of information for the cardiologist, cardiac surgeon, intensivist, and the emergency department physician.
The first section of the book addresses the basics of TEE. The topics range from the physics of ultrasound to the basic TEE examination, and to more commonly encountered anatomic variants and artifacts. The chapter that describes the controls on the ultrasound machine has many TEE images representative of how manipulation of a certain control changes the picture and is most helpful in understanding how to optimize the image acquired. The chapter entitled Quantitative Echocardiography, which includes applications of Doppler technology in the assessment of stenotic versus  regurgitant lesions (specifically the proximal isovelocity surface area, or PISA, method) and equations necessary for intracardiac pressure measurements, is a detailed yet compact introduction to subsequent sections in which various pathologies are addressed individually.
The second section reviews all of the valvular disorders and prosthetic valves along with left ventricular diastolic dysfunction, right ventricular function, and cardiomyopathies in great detail. Although a separate chapter on mitral valve repair, focusing on different surgical techniques and concerns, is particularly useful in understanding the surgeon's perspective, there is repetition of inconsistent information regarding the anatomy of the mitral valve. For example, chapter 7 on the mitral valve mainly classifies chordae tendineae as primary, secondary, and tertiary, whereas chapter 8 on mitral valve repair draws attention to the difference between commissural chordae and leaflet chordae, further dividing them into three groups: paramedial, central, and paracommissural. This causes confusion as these two consecutive chapters are reviewed.
The third section covers miscellaneous scenarios, such as aortic surgery, heart failure surgery, congenital heart disease, and cardiac masses. The chapter on heart failure surgery, which explains concerns and considerations regarding heart transplantation and ventricular assist devices, is particularly thorough and well organized. The chapter on epicardial and epiaortic echocardiography, with multiple pictures representing every imaging plane described in the text, is very informative. This section concludes with a chapter that discusses TEE as a diagnostic and a monitoring tool during noncardiac surgery.
The fourth section consists of two chapters discussing TEE's role outside the operating room, specifically in the critical care unit and in the emergency department. They focus on the causes of hemodynamic instability, along with chest trauma, aortic dissection, and aortic disruption.
Advances in echocardiography are discussed in the fifth section. The newer technologies included are three-dimensional echocardiography, contrast-enhanced ultrasonography, strain rate, tissue strain rate, and two-dimensional speckle tracking echocardiography. This chapter is the most difficult to read due to the highly technical information about these emerging modalities. The authors acknowledge that more research is needed before some of these technologies are routinely applicable to the clinical setting. This last section also includes information regarding training and certification in TEE.
Appendices provide easy access to many tables that include information regarding normal chamber dimensions and several parameters used in determination of the severity of certain disorders. This section also summarizes the methods and equations used in quantitative echocardiography. Normal Doppler values of prosthetic valves are also grouped under this section.
The educational component of this book must be mentioned. There are multiple questions at the end of each chapter, with answers (some with lengthy explanations) at the end of the book. In addition, there is a CD attached with 150 questions, 50 of which are video based.
The numerous echocardiographic images that complement the text are impressive in their clarity. These images make the text much easier to read and understand. For example, chapter 12 uses these pictures in abundance when demonstrating the grading of left ventricular diastolic dysfunction. Chapter 5, while reviewing the recommended tomographic planes, uses not only echocardiographic images but also anatomic representations illustrating how an imaging plane cuts through the heart, for better three-dimensional understanding of the particular view obtained.
The text gives useful tips regarding the manipulation of the TEE probe for better image acquisition and also technical recommendations for more accurate Doppler imaging. As the text focuses on technical aspects of TEE examination of cardiac pathologies, the physiology, pathophysiology, and treatment options are integrated into its content as appropriate. This approach provides a thorough understanding of the pathology being discussed in that particular chapter.
This book is by no means a quick read for a sonographer who might be looking for brief guidance in his or her clinical practice. However, it is a comprehensive review book for those who want to be certified in TEE and invaluable educational material for teaching through the many questions provided both in the book and in the accompanying CD. Aiming to enhance not only the skill but also the knowledge level for more accurate decision-making in the surgical and nonsurgical setting, this book is an invaluable reference text for the practitioner who routinely performs advanced TEE.
