As a new rapid prototyping technology，three-dimensional（3D）printing technology can display the complex intracardiac anatomy intuitively and comprehensively.In recent years，3D printing technology is widely used in the diagnosis and treatment of cardiac diseases such as congenital heart disease，valvular disease and arrhythmia.By extracting different imaging data as CT，MRI or ultrasound images and image post-processing，a 3D model can be printed.This article aims to introduce the application and progresses of 3D printing technology derived from ultrasound images in the diagnosis and treatment of cardic diseases .
