Percutaneous transcatheter aortic valvuloplasty is seriously limited by high restenosis rates. We report a case where the use of a buddy-catheter technique during balloon inflation allowed increased focused force onto calcified stiff commissures with an increase in resultant valve area. This technique may result in further valve area enlargement and decrease the restenosis rate.
经皮经导管主动脉瓣球囊成形术受到高再狭窄率的严重限制。我们报告了一例在球囊扩张期间使用双导管技术的病例，该技术可增加对钙化僵硬瓣叶联合处的集中作用力，从而增加瓣膜面积。该技术可能会进一步扩大瓣膜面积并降低再狭窄率。
