Calcific degenerative aortic stenosis is the most frequent valve disease in the western population. Transcatheter aortic valve implantation procedures are significantly increasing, as they now represent the first choice in inoperable patients and have been shown to be non-inferior to cardiac surgery in patients at high and intermediate surgical risk.
