The incidence of valvular heart disease (VHD) increases with age, and its principal therapy is valve replacement. However, in recent years, the emergence of transcatheter interventions has changed the traditional therapy, making high-risk patients of surgery see dawn of hope. 3D printing technology has developed rapidly since it was applied to the medical field in 1990. Moreover, it has been widely applied in many surgical majors via refined reduction technology. However, the application of 3D printing technology in cardiovascular surgery is still in the preliminary stage, especially in the field of VHD. This article aims to review basic principles of 3D printing technology, its advantages in the therapy of VHD, and its current status of clinical application. Furthermore, this article elaborates current problems and looks forward to the future development direction.
