In aortic valve replacement, severe calcification of the sinotubular junction is a limitation in the application of the rapid deployment Edwards Intuity valve system. This is illustrated by a case presentation in which discrepancies of shape and diameter between sizer and valve mounted on the deployment system resulted in discarding the prosthesis and performing a biocomposite root replacement instead. Modification of the valve sizer will allow for safer sizing because the sizing process will mimic the implantation process more accurately.
在主动脉瓣置换术中，窦管交界处的严重钙化是快速部署爱德华兹Intuity瓣膜系统应用中的一个限制因素。这在一个病例报告中得到了体现，在该病例中，尺寸测量器与安装在部署系统上的瓣膜之间的形状和直径差异导致废弃了假体，转而进行生物复合根部置换。瓣膜尺寸测量器的改进将使尺寸测量更安全，因为尺寸测量过程将更准确地模拟植入过程。
