This book serves as a comprehensive guide to pediatric cardiac computed tomography (CT), particularly for patients with congenital heart disease. Congenital heart disease (CHD) is the leading cause of congenital abnormalities (8/1000 of live births). Over the past two decades, the diagnostic medical approach has significantly changed with a considerable increase in the number of CT studies in pediatric patients.  Preoperative surgical or interventional planning for children with CHD remains crucial and challenging, but despite this and the advancement in the development of new CT techniques and radiation dose reduction methods, there are limited books addressing pediatric cardiac CT. This work fills that gap by offering a complete look at the techniques and clinical utilization for pediatric cardiac CT with liberal use of images. The text begins with overarching themes of pediatric cardiac CT, like its advantages and techniques, and moves into covering differentareas of the heart and possible presentations, like atrioventricular connections and cardiac tumors. Each chapter begins with a short introduction section followed by preoperative and postoperative cardiac CT imaging, management approach, and short-term and long-term outcomes. This book also describes the novel technologies being used for three-dimensional modelling and three-dimensional printing in the surgical preparation of patients with complex congenital heart disease. This book is the first to address pediatric cardiac CT image fusion to fluoroscopy to guide cardiac catheterization in patients with complex congenital heart disease. Radiation dose reduction during cardiac catheterization is also an important part of diagnostic and interventional cardiac catheterization that is covered in detail. The book concludes with an overarching look of the role cardiac CT plays in the pre- and post-operative evaluation of congenital heart disease in children. This book is an ideal guide for pediatric radiologists, pediatric cardiologists, pediatric cardiothoracic surgeons, related trainees, and any physician interested in advanced cardiac imaging.
