The original Ozaki technique involves sizing and trimming the neovalve cusps during cross-clamp. It leads to prolongation of the ischaemic time, as compared to standard aortic valve replacement. We use preoperative computed tomography scanning of the patient's aortic root to develop personalized templates for each leaflet. With this method, autopericardial implants are prepared before the initiation of the bypass. It permits maximally adopting the procedure to the patient's individual anatomy and to shorten the cross-clamp time. We present a case of a computed tomography-guided aortic valve neocuspidization and concomitant coronary artery bypass grafting with excellent short-term results. We discuss the feasibility and technical details of the novel technique.
最初的小崎技术包括在主动脉阻断期间对新瓣膜瓣叶进行尺寸测量和修剪。与标准主动脉瓣置换术相比，这会导致缺血时间延长。我们利用患者主动脉根部的术前计算机断层扫描来为每个瓣叶制作个性化模板。通过这种方法，在体外循环开始前制备自体心包植入物。这使得该手术能够最大程度地适应患者的个体解剖结构，并缩短主动脉阻断时间。我们展示了一例计算机断层扫描引导下的主动脉瓣新瓣叶形成术及同期冠状动脉旁路移植术，短期效果良好。我们讨论了这项新技术的可行性和技术细节。
