Valve Hemodynamic Optimization Based on Doppler-Echocardiography vs Catheterization Measurements Following ViV TAVR (NCT05459233)

Valve Hemodynamic Optimization Based on Doppler-Echocardiography Versus Catheterization Measurements Following Valve-in-Valve TAVR: A Prospective Randomized Trial

🟢 Recruiting Observational / Diagnostic 🩺 Clinical Procedure Protocol Sponsor: Institut universitaire de cardiologie et de pneumologie de Québec, University Laval

🩺 Plain-English Summary (8th-Grade Level)

Data on valve performance following ViV-TAVR has usually been obtained with the use of Doppler-echocardiography. However, some reports have shown significant discordances in the evaluation of mean transvalvular gradient between echocardiography and catheterization, with an overestimation of the real gradient with echo (vs. cath) in most cases. Thus, the incidence of procedural-device failure may be lower than that reported in the ViV-TAVR literature,
