Key result
Ozaki procedure offers superior hemodynamics to biological AVR without requiring lifelong anticoagulation.
Why the study?
Aortic valve neocuspidization with fixed autologous pericardium offers a versatile alternative to complex aortic valve repair with better hemodynamics and no lifelong anticoagulation compared to existing valve replacements.
The Ozaki procedure provides a versatile, reproducible surgical alternative for aortic valve disease with favorable hemodynamics and no need for lifelong anticoagulation.
May warrant selective use in anticoagulation-averse patients; leaves open need for randomized trials on durability.
Aortic valve neocuspidization with fixed autologous pericardium according to the Ozaki technique has been proven to be an effective therapy for the treatment of aortic valvulopathies of various entities (aortic stenosis, aortic regurgitation, aortic valve endocarditis) in both tricuspid and bicuspid aortic valves. Thus, aortic valve neocuspidization with fixed autologous pericardium represents a versatile alternative to complex aortic valve repair, with better hemodynamics compared to biological aortic valve replacement and without the need for lifelong anticoagulation, which characterizes mechanical aortic valve replacement. The authors meticulously describe all the technical steps of this highly reproducible, standardized procedure.

Krane et al. (2021) conducted a review in Aortic valvulopathies (aortic stenosis, aortic regurgitation, aortic valve endocarditis). Aortic valve neocuspidization (the Ozaki procedure) vs. Biological or mechanical aortic valve replacement was evaluated. Aortic valve neocuspidization (the Ozaki procedure) is a versatile alternative to aortic valve replacement, offering better hemodynamics than biological valves without requiring lifelong anticoagulation.
