A 48-year-old man underwent aortic root remodeling for a giant aneurysm of sinus of Valsalva, 98 mm in diameter, as well as a bicuspid aortic valve. The aortic valve was defined as type 0(L-R) according to Sievers classification and the aortic annulus was highly dilated up to 35 mm. Geometric height of the left and right cusps were 22 mm and 32 mm in diameter, respectively. Dacron straight graft of 24 mm was chosen and each tongue was then created in a 180°fashion. After completion of root reconstruction, external circular suture annuloplasty using CV-0 expanded polytetrafluoroethylene (ePTFE) was made to adjust the annulus down to 22 mm in diameter. The free margin of both cusps were centrally plicated to raise the effective height to 9 mm. Postoperative echocardiography at 2 year showed trivial aortic regurgitation but no root re-dilatation. Remodeling with external circular suture annuloplasty is a reproducible and reliable method to stabilize the root, even for the patient with a giant aneurysm of sinus of Valsalva.
一名48岁男性因直径98毫米的巨大瓦尔萨尔瓦窦瘤以及二叶式主动脉瓣接受了主动脉根部重塑手术。根据西弗斯分类法,主动脉瓣被定义为0型(左-右),主动脉瓣环高度扩张至35毫米。左、右瓣叶的几何高度分别为直径22毫米和32毫米。选用了直径24毫米的涤纶直型移植物,然后以180°方式制作每个舌片。根部重建完成后,使用CV-0膨胀聚四氟乙烯(ePTFE)进行外部环形缝合瓣环成形术,将瓣环直径调整至22毫米。两个瓣叶的游离缘在中央折叠,将有效高度提高至9毫米。术后2年的超声心动图显示有微量主动脉瓣反流,但无根部再扩张。即使对于患有巨大瓦尔萨尔瓦窦瘤的患者,采用外部环形缝合瓣环成形术进行重塑也是一种可重复且可靠的稳定根部的方法。
