Trial Outcomes & Findings for MitraClip Russia Trial (NCT NCT04350372)

NCT ID: NCT04350372

Last Updated: 2022-06-14

Results Overview

Successful implantation of the MitraClip NT device resulting in a decrease in the MR severity grade as assessed from the discharge echocardiogram (10-day echocardiogram will be used if discharge is unavailable or uninterpretable). Subjects who die or undergo mitral valve surgery before discharge will be considered a failure for the procedure
