Improved visualization methods provide the necessary anatomical and spatial information in patients with complex cardiac anomalies. 2-dimensional imaging may be limited in its representation of true 3-dimensional relationships. The use of 3D printing has expanded the possibilities of creating physical models that overcome the limitations of the 2D screen. Many researchers have reported on the use of 3D printing for preoperative planning in patients with different causes of heart failure. This article aims to review the innovative uses of this technology in creating individualized models to improve the quality of treatment.
