Normal TEE cardiac structures are described and compared with the corresponding anatomical specimens focusing on the fundamental as well as the details of the cardiac structures, providing a detailed understanding of the anatomy that has not previously been possible with either real-time transthoracic echocardiography (TTE) or reconstructed 3D TEE imaging technology. The atlas contains a large number of challenging cardiac pathology cases observed in clinical settings and based of the combined experience of five outstanding institutions in Europe and United States. Each case is accompanied by a brief presentation and discussion of the value of the imaging modality to effective diagnosis.

Available in PDF, EPUB and Kindle. Book excerpt: Basic Transesophageal and Critical Care Ultrasound provides an overview of transesophageal ultrasound of the heart, lung, and upper abdomen as well as basic ultrasound of the brain, lung, heart, abdomen, and vascular system. Ultrasound-guided procedures commonly used in critically ill patients are also covered. With more than 400 clinical images, this well-illustrated text and its accompanying videos demonstrate new developments and challenges for those interested in mastering basic transesophageal echocardiography (TEE) and bedside surface ultrasound. Each chapter is presented in an easy-to-read format that includes color diagrams and ultrasound images which optimize interactive learning for both novice and experienced clinicians. The book is divided into two parts. The first is dedicated to basic TEE while the second provides focused coverage of bedside ultrasound. The book also includes chapters on extra-cardiac TEE and ultrasound of the brain—unconventional areas that will become more important in the future as clinicians evaluate not only the etiology of hemodynamic instability but also the impact on multiple organs and systems such as the kidney, liver, splanchnic perfusion, and brain. This text is an invaluable resource to those preparing for the National Board of Echocardiography’s Examination of Special Competence in Basic Perioperative Transesophageal Echocardiography (PTEeXAM) and its equivalents outside the USA and Canada. In addition, it prepares physicians for the American College of Chest Physician’s critical care ultrasound certification. The contents follow the syllabus of the TEE basic echo exam to ensure complete coverage of a trainee's requirements. It also includes sample questions and two helpful mock exams. Written by a multidisciplinary team of experts in TEE, the book is a must-have for those in training and in practice.

Available in PDF, EPUB and Kindle. Book excerpt: Echocardiography Pocket Guide: The Transthoracic Examination was recently awarded with 4 Stars for Doody's Book Review! Developed for medical students, residents, cardiologists, and sonographers, Echocardiography Pocket Guide: The Transthoracic Examination presents a comprehensive, easy-to-understand, and practical guide to the performance and interpretation of the transthoracic examination. Key features include: Practical step-by-step approach to the transthoracic examination Accurate depictions of echocardiographic anatomy Basic principles of ultrasonography Illustrated charts summarizing normal and abnormal cardiac structure and function Foreword by Scott D. Solomon, MD Director, Noninvasive Cardiology at Brigham and Women’s Hospital Echocardiography is a manual skill. Unlike other imaging techniques, where a patient is positioned and a technician may press a series of buttons, echocardiography requires that a skilled operator apply a transducer manually to a patient’s thorax. Moreover, as echocardiography is not a tomographic technique, the images obtained are neither uniform nor guaranteed to be of a certain quality or even spatial location. Hence, the quality of the images obtained is directly dependent on that operator’s skill and experience; the success of the examination begins and ends at the hands of the person holding the transducer. Echocardiography Pocket Guide: The Transthoracic Examination by Bernard Bulwer and José Rivero, provides an introduction to cardiac imaging with echocardiography for anyone interested in learning this skill. It will appeal to sonographers in training and beyond. It will appeal to cardiology fellows, emergency physicians, and any physician or health professional interested in learning echocardiography from a hands-on perspective. In addition to providing an expert introduction to the process of performing an echocardiographic examination, this book is expertly illustrated and will guide users through the first steps of interpreting echocardiographic images. A good sonographer needs to know what to look for, and how to look for it. While a solid understanding of the kinds of pathology that are typically seen are essential in an echocardiographers training, the most important thing an echocardiographer can learn is to recognize normal, as only then can he or she appreciate and understand deviations from normality. As echocardiography transitions from a technology dominated by subspecialists to one that likely will be embraced by a growing number of practitioners, there will be a growing need for very practical instruction in this art, which has generally been taught by apprenticeship. This shift will likely be driven by the advent of smaller, more efficient and cheaper hand-held and portable echocardiographic devices that are beginning to transform cardiac imaging. This handbook has a central role in this transition, and will provide a wide range of clinicians with a foundation for the practice o
