Trial Outcomes & Findings for PRESERVE-MITRAL Post-Market Registry (NCT NCT03283722)

NCT ID: NCT03283722

Last Updated: 2025-02-11

Results Overview

This is determined by assessing the level of mitral valve regurgitation using echo, in subjects at 12-months post-procedure compared to the level at baseline. The levels of regurgitation, level 0-4, correspond to the American Society of Echocardiography (ASE) guidelines ranging from no MR, Mild MR, Moderate MR, Moderate- to-Severe MR and Severe MR. A percentage number is calculated to reflect how many participants had an MR improvement.

PRIMARY outcome

Timeframe: 12 months

Population: Data reported is for the Successfully Implanted (IMP) cohort n=180.

This is determined by assessing the level of mitral valve regurgitation using echo, in subjects at 12-months post-procedure compared to the level at baseline. The levels of regurgitation, level 0-4, correspond to the American Society of Echocardiography (ASE) guidelines ranging from no MR, Mild MR, Moderate MR, Moderate- to-Severe MR and Severe MR. A percentage number is calculated to reflect how many participants had an MR improvement.

SECONDARY outcome

Timeframe: At discharge from hospital (up to 7 days) and at first follow-up (3-6month)

Population: Of the 180 implanted subjects, 161 returned for the first follow-up visit at 3-6 months and had an echo performed, primarily due to standard of care practices at participating facilities.

This was determined by assessing the level of mitral valve regurgitation using hemodynamic performance, in subjects at discharge and 3-6 months post-procedure compared to the level at baseline. The levels of regurgitation, level 0-4, correspond to the ASE guidelines ranging from no MR, Mild MR, Moderate MR, Moderate-to-Severe MR and Severe MR

Population: Data reported is for the Successfully Implanted (IMP)

New onset of AF is defined as when the subject did not present with prior history of AF at baseline nor was AF detected at baseline visit, but AF did manifest post procedure and was either diagnosed during the study visits (discharge, 3-6 months or 12 months visit) or was otherwise diagnosed during the duration of subject participation in the study. The incidence of new onset AF will be evaluated at discharge, first follow up (3-6 months) and at second follow up (12 months). This endpoint is analyzed for the Successfully Implanted (IMP) cohort and provided as a Kaplan-Meier analysis.
