A 33-year-old man presented with severe aortic insufficiency due to a prolapsed bicuspid aortic valve. The ventriculoaortic junction was dilated to 29 mm without root dilatation, and external ring annuloplasty was performed using a Gelweave (Terumo, Tokyo, Japan) graft to reduce the size to 22 mm. The leaflets were repaired by dividing and suturing a raphe between the right and left cusps. This combination provided adequate coaptation depth (8 mm) and showed excellent results, with trivial aortic insufficiency. This approach is suitable for repair of a bicuspid aortic valve with a dilated ventriculoaortic junction without root dilatation.
一位 33 岁男性因二尖瓣脱垂导致严重主动脉瓣关闭不全。主动脉瓣环至心室流出道交界处扩张至 29mm，无根部扩张，使用 Gelweave（日本东京 Terumo）移植物行外环成形术将其缩至 22mm。通过在瓣叶的右侧和左侧之间分割和缝合嵴来修复瓣叶。这种方法提供了足够的对合深度（8mm），并且效果极佳，仅有轻微的主动脉瓣关闭不全。这种方法适用于修复瓣环至心室流出道交界处扩张而根部无扩张的二叶式主动脉瓣。
