Abstract
Congenital and acquired valvular heart diseases are a global problem of the healthcare system. A huge number of prosthetic heart valve surgeries are performed annually, but there is still no ideal artificial substitute for a heart valve. The development of new prosthetic heart valves continues continuously, and includes an assessment of the functioning of prosthetic valves and the study of their hydrodynamic characteristics. Hardware pulse duplication systems (pulse duplicators) have been developed and used for such studies. The article discusses the purpose and functions, mechanical components, the principle of operation of the device, software, analysis capabilities, advantages and disadvantages of such systems.
