Midterm Results of Neocuspidization of the Aortic Valve with Ozaki Technique in Adults

ABSTRACT

The neocuspidization technique using autologous pericardium (AVNeo^®) is a recent alternative for aortic valve replacement in selected patients. Between 2019 and 2023, we applied it in 56 patients, evaluating surgical outcomes, survival, reintervention rates, and clinical and echocardiographic results. We analyzed its advantages, patient selection criteria, limitations, and management of bicuspid valves. We also assessed whether it is suitable for all patients and discussed the midterm outcomes observed. AVNeo^® may offer a promising option, especially for younger patients, by preserving native anatomy and avoiding prosthetic materials, though long-term data and further research are still needed.
