Transcatheter aortic valve implantation can be successful in selected patients with annuli beyond the current recommended limits for available transcatheter valves. Over-expansion of balloon-expandable valves beyond current guidelines may play a role. The limits of over-expansion of balloon-expandable valves are not well understood.
对于瓣环超出当前可用经导管瓣膜推荐限度的特定患者,经导管主动脉瓣植入术可能成功。球囊扩张式瓣膜超出当前指南的过度扩张可能起了作用。球囊扩张式瓣膜的过度扩张限度尚未得到充分了解。
