The reimplantation technique for valve sparing aortic root replacement (David I) has improved management of patients with aortic root aneurysm and structurally normal aortic valves. The Valsalva graft (Gelweave Valsalva, Sultzer Vascutek, Renfrewshire, Scotland) further simplified the procedure by offering a root prosthesis with preformed neo-sinuses that may reduce physiologic stresses on valve leaflets and improve long-term valve durability. However, in-conduit suturing of the aortic valve annulus and a small rim of sinus remnant to the graft sinuses may create folds of the sinus remnant that lead to bleeding or distortion of the prosthetic root. We report a method to minimize crimping of the aortic graft sinuses.
保留瓣膜的主动脉根部替换术(David I)的再植入技术改善了主动脉根部瘤和结构正常的主动脉瓣患者的治疗效果。Valsalva 移植物(Gelweave Valsalva、Sultzer Vascutek、Renfrewshire、Scotland)通过提供带有预成型新窦的根部假体进一步简化了该手术,这可能减轻瓣叶的生理压力并提高长期瓣膜耐久性。然而,在 conduit 中缝合主动脉瓣环和窦部残余的一小部分边缘到移植物窦部可能会导致窦部残余的折叠,从而导致出血或假体根部变形。我们报告了一种最小化主动脉移植物窦部卷曲的方法。
