Book excerpt: This book offers readers a comprehensive introduction to the techniques and application of 3D printing in cardiovascular medicine. To do so, it addresses the history, concepts, and methods of 3D printing, choice of printing materials for clinical purposes, personalized planning of cardiac surgery and transcatheter interventions with patient-specific models, enhancement of patient-physician communication, simulation of endovascular procedures, and advances in 3D bio-printing. The book particularly focuses on the application of 3D printing to improve the efficacy and safety of cardiac interventions, and to promote the realization of precision medical care. The book gathers contributions by an international team of experts in the field of cardiovascular medicine, who combine the latest findings with their own practical experience in using 3D printing to support the diagnosis and treatment of a wide range of cardiovascular diseases. They present in-depth discussions in the fields of congenital heart disease, valvular disease, coronary artery disease, cardiomyopathy, left atrial appendage occlusion, cardiac tumors and vascular diseases.
