Biological prostheses for cardiovascular surgery – a half-century history and development prospects

HighlightsSurgical correction of cardiovascular deformities is inextricably linked with the use of prostheses. The development and clinical testing of biological prostheses has been conducted under the guidance of the Member of Russian Academy of Sciences Leonid Barbarash at the Kuzbass Cardiology Center for more than 50 years. The uniqueness of the developed products lies in the use of a new biological tissue preservative – ethylene glycol diglycidyl ether, and an integrated approach involving the development and manufacture of products, study of long-term replacement outcome, causes of prosthetic dysfunction and genetic aspects of the use of bioprostheses in patients. AbstractThis article highlights the main achievements in the development of biological prostheses for cardiovascular surgery under the leadership of the Member of Russian Academy of Sciences L.S. Barbarash since the 1980s. Throughout this period, Leonid Barbarash and his team have developed and mass-produced various designs of bioprosthetic heart valves and tissue preservation methods, arterial grafts, and patches. The article presents the results of developing next-generation vascular biodegradable grafts capable of complete remodeling and stimulating endothelialization after the implantation into the vascular bed. Moreover, we conducted a series of genetic studies evaluating the significance of gene polymorphisms of various pathogenetic pathways involved in the pathological calcification of native heart valves and their prostheses.
