Aortic Valve Stenosis study: Doppler-echocardiography
Official title Valve Hemodynamic Optimization Based on Doppler-Echocardiography vs Catheterization Measurements Following ViV TAVR
ClinicalTrials.gov ID: NCT05459233
What this study is testing
- What it's testing
- It aims to see if echo overestimates valve pressure compared to catheter readings, which could change how we judge valve success.
- Who it's for
- It is for adults who have aortic valve stenosis, aortic valve regurgitation, or a failed valve prosthesis and are getting a valve‑in‑valve TAVR procedure.
- What's involved
- Participants will have their valve function measured by both Doppler‑echocardiography and catheterization during the procedure.
