Trial Outcomes & Findings for PREVAIL-20J - Transfemoral Placement of 20mm Aortic Balloon Expandable Transcatheter Valve Trial (NCT NCT01419015)

NCT ID: NCT01419015

Last Updated: 2020-08-06

Results Overview

Improvement of the aortic valve area (AVA) and New York Heart Association (NYHA) functional classification from baseline to 1 year after the procedure. NYHA functional classification of heart failure based on how much a patient is limited during physical activity. The rating ranges from I-IV, with the lowest (I) as no limitations and the highest (IV) unable to carry on any physical activity without discomfort. The AVA at 1 year \>= 0.65 cm2 indicates improvement. This outcome measure shows the percentage of patients that had an improvement in both NYHA Class and AVA. Note: One patient did not complete a 6-month echo.
