ECHOCATH
Valve Hemodynamic Optimization Based on Doppler-Echocardiography vs Catheterization Measurements Following ViV TAVR
AI Description
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,

- PROCEDURE: Doppler-echocardiography
- PROCEDURE: Invasive hemodynamic measurements
What it measures
- Changes in Quality of life (Efficacy), Change in quality of life as evaluated by the Kansas City Cardiomyopathy Questionnaire (KCCQ). All score are represented on a 0-to-100-point scale (lower scores represent more severe symptoms and/or limitations and scores of 100 indicate no symptoms, no limitations, and excellent quality of life).The KCCQ is a 7 domains questionnaire; symptom frequency, symptom burden, symptom stability, physical limitations, social limitations, quality of life and self-efficacy., 12 months follow-up
- Periprocedural complications (Safety), Periprocedural complications including in-hospital mortality, stroke, annular rupture, coronary obstruction, new-onset left bundle branch block, need for permanent pacemaker implantation and conversion to open heart surgery., Periprocedural
