New Ozaki Procedure Overview

Seventeen years have passed since the Ozaki procedure started in 2007.In the first series we reported in 2010, we used the first generation template and sizer, and we had already achieved excellent outcomes with them.Many surgeons worldwide have started using the Ozaki procedure, and their reports are now being published from all over the world.However, with the conventional templates, actual points to suture on the new cusp could vary depending on the surgeons because the dots on the template were not the actual suture points.We also experienced 3 cases in which coronary artery occlusion by the valve cusps occurred after releasing the aortic cross-clamp.The previous sizer also had some issues because of the position of the handle and the top corner height.And it might cause inaccurate measurements of each cusp size.Based on the above experience, we have gradually upgraded the template and sizer to improve the outcomes and standardize the procedure.The current ones are the third generation, and each shape is completely different from the previous ones.With this new template and sizer, the tips for actual procedures have also changed.Here, we will once again describe the Ozaki procedure using the third generation sizer and template as the "New Ozaki Procedure."Operative Techniques in Thoracic and Cardiovasculary Surgery 30:246À274
