Extensively revised from cover to cover, Kendig and Wilmott's Disorders of the Respiratory Tract in Children, 10th Edition, continues to be your #1 choice for reliable, up-to-date information on all aspects of pediatric respiratory disorders. This highly respected reference is accessible to specialists and primary care providers alike, with coverage of both common and less common respiratory problems found in the newborn and child. Detailed and thorough, this edition covers basic science and its relevance to today's clinical issues as well as treatment, management, and outcomes information, making it an ideal resource for day-to-day practice as well as certification or recertification review and other professional examinations such as pHERMES. - Offers an international perspective on the whole spectrum of the specialty, including a robust video library with demonstrations of key procedures and bronchoscopic views. - Uses a consistent format with succinct, bulleted text, and contains abundant tables and figures, chapter summaries, and more than 500 full-color images to convey key information in an easy-to-digest manner. - Contains eleven new chapters and discusses timely topics such as big data and -omics in respiratory disease, COVID-19, obesity and its consequences, and vaping and nicotine addiction among children and young people. - Provides up-to-date instruction on key procedures, such as bronchoscopy and pulmonary function testing. - Highlights the knowledge and expertise of nearly 90 new authors who are global experts in the fields of pediatrics, pulmonology, neurology, microbiology, cardiology, physiology, diagnostic imaging, critical care, otolaryngology, allergy, and surgery.

Right ventricular (RV) function has proven to be a prognostic factor in heart failure with reduced and preserved left ventricular ejection fraction or in pulmonary arterial hypertension. RV function is also a cornerstone in managing relatively novel clinical issues, such as mechanical circulatory support devices or grown-up congenital heart diseases. Despite the notable amount of circumferentially oriented myofibers in the subepicardial layer of the RV myocardium, the non-longitudinal motion directions are often neglected in the everyday assessment of RV function. The complex RV contraction pattern, however, incorporates distinct mechanical components. 3D imaging may enable capturing subtle RV dysfunction, which can be undetectable by conventional methods. Novel 3D-based parameters may allow an earlier diagnosis and better risk stratification of numerous cardiac and primarily non-cardiac diseases.
