The book is based primarily on real images in cardiac surgical anatomy with a focus on congenital heart defects. Anatomy is one of the most fundamental disciplines on which clinical practices in surgical departments are based, and it is of great significance ptuticularly for the understanding and treatment of congenital heart defects. In such disciplines, practical experiences are much more important than are theoretic knowledge and instruments. My hope is that this unique book, which analyzes different kinds of cardiac malformation specimens in depth, will inspire colleagues to further develop novel methods in the diagnosis and treatment of congenital heart defects.
