Non-Invasive MOnitoring in Transcathether Aortic Valve Implantation
- Conditions
- Aortic Valve Disease
- Registration Number
- NCT05840757
- Lead Sponsor
- University of Basel
- Brief Summary
In patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) minimal evidence is available for invasive hemodynamic monitoring and no evidence for tools able to measure traditionally invasive parameters non-invasively for peri-procedural guidance and post-interventional management.
The aim of this study is to evaluate the effectiveness and safety of a non-invasive hemodynamics monitoring tool called ClearSight for monitoring during TAVI procedures compared with standard invasive measurements.
- Detailed Description
In patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) minimal evidence is available for invasive hemodynamic monitoring and no evidence for tools able to measure traditionally invasive parameters non-invasively for peri-procedural guidance and post-interventional management.
The aim of this study is to evaluate the effectiveness and safety of a non-invasive hemodynamics monitoring tool called ClearSight for monitoring during TAVI procedures compared with standard invasive measurements.
The ClearSight monitoring system works non-invasively by utilizing an inflatable finger cuff which adjusts automatically to measure the arterial blood pressure which enables the calculation of parameters such as cardiac output or index. Multiple studies have demonstrated the reliability and feasibility of continuous non-invasive monitoring, in different settings, however it was never performed in patients undergoing TAVI.
The ClearSight monitoring system will be directly compared to invasive measurements of hemodynamic parameters during the procedure. In addition, information regarding baseline hemodynamics and its changes during/after procedure may give important information on peri- and post-procedural management and short-term outcomes and discharge planning. A tool, providing this information non-invasively with the same accuracy might result in a major improvement in daily practice..
