Background: Aortic valve neocuspidization (AV Neo) using glutaraldehyde‐treated autologous pericardium was first reported by Ozaki et al. in 2007. This technique has become an alternative to tissue and mechanical valve in selected patients as long‐term anticoagulation is not required and shows promising midterm results and durability. Method: A comprehensive search was performed on the major database using the search terms "Ozaki technique" AND "Aortic Valve Neocuspidization" AND "AV Neocuspidization" AND "Autologous pericardium" AND "glutaraldehyde‐treated autologous pericardium." Articles up to August 1st, 2021 were included in this study. Results: A total of nine studies with a total of 1342 patients were included. The mean age was 67.36 and 54.23% were male. 66.32% and 23.92% of patients had aortic stenosis and aortic regurgitation, respectively. 66% of patients had a native tricuspid aortic valve (AV) and 31.37% of patients' native AV was bicuspid. Three studies reported their experience performing AV Neo via ministernotomy. Conclusion: AV Neo can be a suitable alternative to surgical AV replacement in selected patients. The short‐ and midterm outcomes are comparable without the need for long‐term oral anticoagulation. Long‐term follow‐up data are required for this novel approach to be widely adopted.
