While it is the main viable option in the growing child and young adult, the Ross procedure has expanded its applicability to older patients, for whom long-term results are equivalent, if not superior, to prosthetic aortic valve replacement. Strategies aiming at mitigating long-term autograft failure from root enlargement and valve regurgitation have led some to advocate for root reinforcement with prosthetic graft material. On the contrary, we will discuss herein the rationale for a tailored approach to the Ross procedure; this strategy is aimed at maintaining the natural physiology and interplay between the various autograft components. Several technical maneuvers, including careful matching of aortic and autograft annuli and sino-tubular junction as well as external support by autologous aortic tissue maintain these physiologic relationships and the viability of the autograft, and could translate in a lower need for late reintervention because of dilation and/or valve regurgitation.
虽然在生长中的儿童和青少年中,Ross 手术是主要可行的选择,但该手术已经扩展到适用于老年患者,其长期结果与假体主动脉瓣置换术相当,如果不比后者差。旨在减轻因根部扩张和瓣膜反流导致的长期自体移植物失败的策略,促使一些人主张使用假体移植物材料来加强根部。相反,我们将在此讨论针对 Ross 手术的定制方法的基本原理;该策略旨在维持自然生理和各种自体移植物成分之间的相互作用。几种技术操作,包括仔细匹配主动脉和自体移植物瓣环以及窦管交界处,并通过自体主动脉组织提供外部支撑,维持这些生理关系和自体移植物的活力,并且可能因为扩张和/或瓣膜反流而降低晚期再次干预的需求。
