Evaluation of ARi With OpSens SavvyWire

Evaluation of the Aortic Regurgitation Index (ARi) Measured With the Opsens SavvyWire to Determine the Correlation Between Regurgitation Evaluation Using Echography and Aortography

The goal of this observational study is to establish the degree of agreement to Aortic Regurgitation (AR) severity during aortic valve intervention between the Aortic Regurgitation Index (ARi) measured by the Opsens SavvyWire, Echography and Aortography in subjects with severe aortic stenosis (AS) undergoing echo guided valve intervention. The main question it aims to answer is how the ARi measured with the Opsens SavvyWire compared with regurgitation evaluation derived by Echography and Aortography.
