This edition will offer the latest diagnostic techniques, case studies, and research findings that have reoriented one's understanding of fetal cardiology. The importance of early and accurate diagnosis cannot be overemphasized as it not only directly impacts the outcomes and quality of life for the patients but also gives insights about the unborn child to the parent. This book equips healthcare professionals with the necessary tools to make a profound difference in the lives of expectant mothers and their unborn children. I extend my appreciation to the authors, contributors, and the medical community for their unwavering commitment to advancing the field of fetal echocardiography.
