 Cardiovascular diseases are the leading cause of morbidity and mortality in the United States. Cardiac tissue engineering is a direction in regenerative medicine that aims to repair various heart defects with the long-term goal of artificially rebuilding a full-scale organ that matches its native structure and function. Three-dimensional 3D bioprinting offers promising applications through its layer-by-layer biomaterial deposition using different techniques and bioinks. In this review, we will introduce cardiac tissue engineering, 3D bioprinting processes, bioprinting techniques, bio-ing materials, areas of limitation, and the latest applications of this technology, alongside its future directions for further innovation.
