The patient-prosthesis mismatch has been reported as an important cause of adverse outcome following aortic valve replacement. The relief of patient-prosthesis mismatch generally requires a reoperation of comprehensive nature, which necessitates an extensive aortic root enlargement. The Konno aortoventriculoplasty represents an efficient treatment option, as this technique provides both extreme root enlargement and relief of the frequently associated subvalvular obstruction. However, the application and conduct of the procedure may somewhat differ from the pediatric Konno procedures.

This article describes our surgical technique adaptation in Konno-aortoventriculoplasty for adult patient-prosthesis mismatch cases, highlighting the differing points from the pediatric-Konno.

据报道，患者与假体不匹配是主动脉瓣置换术后不良结果的一个重要原因。缓解患者假体不匹配通常需要进行全面的再次手术，这需要广泛的主动脉根部扩大。 Konno 主动脉心室成形术代表了一种有效的治疗选择，因为该技术既可以极大地扩大根部，又可以缓解经常相关的瓣膜下梗阻。然而，该手术的应用和实施可能与儿科绀野手术有所不同。

本文介绍了我们在成人患者假体不匹配病例中对 Konno 主动脉心室成形术的手术技术进行的调整，强调了与儿科 Konno 的不同点。
