Application areas

Aortic valve stenosis is the most common valvar disease in industrialized countries. The predominant cause of this disease are degenerative changes. Accordingly, aortic valve stenosis is generally a disease of the elderly; typical symptoms are shortness of breath and loss of consciousness. Due to the elevated stress the heart muscle is also damaged chronically. Aortic valve replacement is the only possible treatment option for most patients. Many elderly patients with aortic stenosis requiring surgical valve replacement cannot undergo this procedure due to high surgical risk. In a transcatheter aortic valve implantation (TAVI) the new valve is delivered crimped inside a catheter to the implantation site through the vasculature and released at the position of the native aortic valve, avoiding open heart surgery and reducing the operative risk.
