Key result
Aortic valve neocuspidization using autologous pericardium has evolved over decades into a reproducible technique that avoids lifelong anticoagulation and provides excellent hemodynamics.
Why the study?
To examine the historical aspects and evolution of aortic valve neocuspidalization using autologous pericardium and assess prior contributions preceding the Ozaki technique.
This historical review highlights that aortic valve neocuspidalization using autologous pericardium is a technique that has evolved over many decades, building upon the foundational work of numerous early cardiac surgeons.
Questions novelty of Ozaki autologous AVR; challenges attribution and leaves open template utility in current practice.
Highlights. The article describes the contribution of foreign and Russian surgeons to the development of aortic valve replacement using autologous tissue, and presents the evolution of the technique. The authors tried to answer the question whether the Japanese professor S. Ozaki actually developed something new or the discovery was already made 40 years ago. At the end of the article, the technique developed by a Russian cardiac surgeon is presented, casting doubt on the use of templates in this procedure. Abstract. Aortic valve replacement using autologous pericardium (neocuspidalization) is becoming an increasingly attractive option that can be applied to a wide range of aortic valve diseases. This technique avoids the need for lifelong administration of anticoagulant drugs, and provides the maximum effective orifice area, resulting in a low transvalvular gradient. The new technique, introduced by Shigeyuki Ozaki, has made the procedure more reproducible with promising medium- and longterm results. But is Ozaki the predecessor of this technique or is “all new is well forgotten old”? This review focuses on the historical aspects of the development of neocuspidalization of the aortic valve using autologous pericardium, the first interventions for valve reconstruction are mentioned, the evolution in the technique of preparation and fixation of the leaflets is reflected.

Комаров et al. (2023) conducted a review in Aortic valve disease. Aortic valve neocuspidization using autologous pericardium was evaluated. Aortic valve neocuspidization using autologous pericardium has evolved over decades into a reproducible technique that avoids lifelong anticoagulation and provides excellent hemodynamics.
