Abstract

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.
