Currently, over 290,000 HV procedures are performed annually worldwide and that number is estimated to triple to over 850,000 by 2050. Thus, the demand for artificial HVs is expanding at a rate of 10-12% per year.  Additive manufacturing is playing a key role in all three main types of prosthetic heart valves.  This presentation will provide a brief summary of the major activities in this area of research, with specific focus on the work ongoing at Colorado State University in Colorado, USA.
