This book is not only a popular science book but also a history of surgery. It unfolds around individuals and events across different stages of cardiac surgery development. As stories progress, it presents the unique scientific journey of mankind’s challenge into the forbidden territory of the heart, which can be aptly described as “medical history as gripping as a novel.” Although this work is a recreation of the author’s The Legends of Cardiac Surgery published ten years ago, the author has added substantial new materials and fresh perspectives while also rectifying certain key historical facts and adding stories about the artificial heart.
