BACKGROUNDPerfect heart valve prostheses have optimized hemodynamics, reduced surgical morbidity, long-lasting durability, and extended patient survival with greater quality of life. Mechanical valves are recommended; however, young children may need anticoagulant medication for life. In this study, we looked at the success rate and viability of aortic valve neocuspidization (AVNeo) surgery for a variety of aortic disorders.METHODSA methodical search strategy was used to fully evaluate the AVNeo results. Boolean operators were used to combine important words like 'Ozaki Procedure,' 'Aortic Valve Neocuspidization,' 'AVNeo,' and associated terms. Reputable databases such as PubMed, MEDLINE, Embase, Web of Science, and Scopus were the focus of our search. Study quality was assessed using a critical evaluation created with the Critical Appraisal Skills Programme tool.RESULTSThe findings are summarized in the 'Results' section that contains descriptive and critical analysis, ramifications, and explanations. According to research, AVNeo improved valve function and had few side effects. Aortic valve neocuspidization has a lower mean pressure gradient and a larger mean efficient orifice area than Trifecta. Aortic valve neocuspidization surgery reduces aortic valve regurgitation and pressure gradients. Postoperative echocardiograms indicated a decrease in peak and a rise in mean pressure gradient.CONCLUSIONThe Ozaki method restores a healthy laminar flow pattern while preventing bivalvular disease. Ozaki procedure should be explored for valve repair in infants with truncal valve and congenital aortic disease. Aortic valve tricuspidization with glutaraldehyde-treated autologous pericardium results in considerable effective orifice area, modest pressure gradients, and little regurgitation.
