Achievement of optimal valve geometry in valve-sparing aortic root repairs is a prerequisite for favorable valve function and, therefore, the simplification of these procedures is of utmost importance. The aim of the study was to determine the feasibility of the new vascular graft for aortic valve reimplantation technique and evaluate the early and intermediate functional results. Five patients with different aortic root and valve pathologies (1 acute aortic dissection, 4 chronic aneurysms, and 1 bicuspid valve) of whom two patients suffered from severe (4+) aortic regurgitation, underwent valve-sparing aortic root repair using the reimplantation technique with the new graft. Three patients required, in addition to the aortic root repair, other procedures on the valve cusps. In all patients, optimal root restoration with no or slight valve insufficiency could be achieved, and these results remained unchanged over the follow-up time of up to two years. The new aortic root graft simplifies aortic root repair using the valve reimplantation technique, and despite its straight form, allows easy restoration of the aortic root, which fits perfectly with patients' anatomy.
在保留瓣膜的主动脉根部修复术中实现最佳瓣膜几何形态是获得良好瓣膜功能的前提，因此简化这些手术至关重要。本研究的目的是确定新型血管移植物用于主动脉瓣再植入技术的可行性，并评估早期和中期的功能结果。五例患有不同主动脉根部和瓣膜病变的患者（1例急性主动脉夹层、4例慢性动脉瘤和1例二叶式主动脉瓣），其中两例患者患有严重（4+）主动脉瓣反流，接受了使用新型移植物的再植入技术进行保留瓣膜的主动脉根部修复。除主动脉根部修复外，三例患者还需要对瓣膜叶进行其他手术。在所有患者中，均可实现无或轻度瓣膜关闭不全的最佳根部修复，并且在长达两年的随访期内这些结果保持不变。新型主动脉根部移植物简化了使用瓣膜再植入技术的主动脉根部修复，尽管其形状笔直，但仍可轻松恢复主动脉根部，与患者的解剖结构完美契合。
