Abstract

Introduction: This case report aims to describe an aortic root enlargement in combination with the replacement of the ascending aorta in a patient presenting with severe aortic valve stenosis.

Case report: A 68-year-old woman with severe aortic stenosis due to a type 0 bicuspid aortic valve and an aortic aneurysm underwent surgery for treatment. The annulus was preoperatively measured with 19 mm. Enlargement was performed by using a tissue patch to create a neo-noncoronary sinus and enlarge the root.

Discussion: Patients with a small aortic root face an increased risk of patient prosthesis mismatch. Enlarging the aortic root can mitigate this, but it extends cross-clamp and overall operative times. This case shows the need for carefully planned surgical interventions to optimize outcomes in complex anatomies.

Conclusions: Each step of the performed surgery is well-established, however the combination and the creation of a neo-noncoronary sinus is not described so far.

0 型主动脉瓣狭窄的主动脉根部扩大和升主动脉置换术。

导言：本病例报告旨在描述一名主动脉瓣重度狭窄患者的主动脉根部扩大术和升主动脉置换术：一位 68 岁的女性因 0 型双尖瓣主动脉瓣和主动脉瘤导致主动脉瓣重度狭窄，接受了手术治疗。术前测量瓣环为 19 毫米。通过使用组织补片创建一个新非冠状动脉窦并扩大主动脉根部：讨论：主动脉根部较小的患者面临着假体与患者不匹配的更大风险。扩大主动脉根部可减轻这种风险，但会延长交叉钳夹和整个手术时间。本病例表明，在复杂解剖情况下，需要精心策划手术干预，以优化手术效果：结论：所实施手术的每个步骤都是成熟的，但迄今为止，还没有人描述过新非冠状动脉窦的组合和创建。
