"This textbook was designed to be a resource on echocardiography in pediatric and congenital heart disease. When first published in 2009, this book filled a void of nearly 10 years between major textbooks in the field. In this textbook we strived to provide a comprehensive source of information for both beginners and advanced practitioners. At the time of the first edition, the "special" topics included 3D echocardiography and fetal echocardiography. When we updated the textbook in 2016, the newer topics were post-Fontan imaging and pregnancy with heart disease. In this updated third edition of our comprehensive textbook, we focused on consolidating recent advances in echocardiography into routine practice. We have incorporated the topics of speckle tracking echocardiography and 3D echocardiography into the chapters discussing ventricular function and cardiovascular lesions. To highlight the progress in our profession, we added new chapters on assessment of the right ventricle, the transitional neonatal circulation, and the role of multimodality imaging. In our "key elements" sections, we continued to emphasize echocardiographic predictors of important clinical outcomes. Many, if not most, of the images and videos have been replaced to give the readers up-to-date examples of essential clinical images"-- Provided by publisher.
