About This Trial
The goal of this observational study is to assess the changes of ascending aortic diameter in patients undergoing transcatheter aortic valve replacement. The main questions it aims to answer are:
1. whether the ascending aortic diameter increases or remains stable after transcatheter aortic valve replacement, especially in patients with preoperative ascending aortic dilatation;
2. the determinant…
