The Texas Children's Hospital Handbook of Congenital Heart Disease is authored by physicians, nurses, and allied staff across a wide variety of disciplines at the Heart Center at Texas Children's Hospital. The book is not intended as a comprehensive textbook in congenital heart disease but rather as a practical handbook to be used by students, residents, fellows, nurses, and congenital heart specialists for the day-to-day management of these complex patients. The Handbook describes the philosophy, protocols, and nuances of management of patients with congenital heart disease at Texas Children's Hospital.
