INTRODUCTION Ozaki et al.1 reported in 2011 their first institutional report about a surgical technique with which they replaced all three aortic valve leaflets using glutaraldehyde-treated autologous pericardium. Since this procedure is not widely spread among cardiac surgeons, but it has been gaining some ground, we aimed to assess the current practice of state-of-the-art aortic valve neocuspidization (AVNeo) and its results. Search Strategy The search strategy using MEDLINE, from 1950 to June 2019, and the PubMed interface was: ("Aortic Valve"Mesh OR "Aortic Valve Stenosis"Mesh OR "Aortic Valve Prolapse"Mesh OR "Aortic Valve Insufficiency"Mesh OR "Bicuspid Aortic Valve" Supplementary Concept OR "Aortic Valve Disease" Supplementary Concept OR "Aortic Valve, Calcification of" Supplementary Concept OR "Heart Valve Diseases"Mesh OR "Heart Valve Prolapse"Mesh OR "Heart Valves"Mesh) AND ("Cardiac Valve Annuloplasty"Mesh OR "Transplantation, Autologous"Mesh OR "Pericardium"Mesh OR “Glutaraldehyde-Treated Autologous Pericardium” OR “aortic valve reconstruction” OR “neocuspidization” OR “Ozaki procedure” OR “Ozaki technique” OR “Ozaki method”). Preoperative echocardiography revealed a peak pressure gradient average of 68.9±36.3 mmHg with aortic stenosis that decreased to 19.5±10.3 mmHg one week after surgery and to 15.2±6.3 mmHg eight years after surgery. Every Like Is Not the Same, But One May Give an Idea of the Other Among the various repair techniques for aortic valve diseases, the leaflet extension technique for AR has been used in cases of severe cusp retraction that cannot be corrected by means of other techniques12-14.
