Clinical Trial Summary

This study is to analyse if the size of the valve can be determined with a preoperative CT scan of the heart in order to prepare the valve preoperatively to save time.


Clinical Trial Description

Patients with severe aortic stenosis undergo aortic valve replacement (AVR). One approach to reduce trauma and operation time is the implantation of a sutureless valve to reduce aortic cross-clamp time due to the missing necessity of suturing the valve. Until now, sizing of the valve was determined intraoperatively using the measuring devices provided by the product manufacturer. Due to the implantation mechanism, the valve has to be collapsed after determination of the size. This is consuming time and can seriously delay the procedure. This study is to analyse if the size of the valve can be determined with a preoperative CT scan of the heart in order to prepare the valve preoperatively to save time. ;
