Key result
M-TEER for FMR shows lower procedural success and higher HF readmissions in Black versus White patients.
Why the study?
Mitral transcatheter edge-to-edge repair is recommended for symptomatic functional mitral regurgitation despite medical therapy, but the influence of sex and race on outcomes remains understudied.
Does sex or race affect outcomes in patients undergoing M-TEER for functional mitral regurgitation?

“Our findings underscore the need for tailored, patient-specific management strategies and highlight the importance of addressing structural inequities in health care to improve outcomes for all patients with FMR.”
Should not yet alter M-TEER candidacy or follow-up by race or sex; leaves open mechanisms and strategies to close outcome gaps.

Does sex or race affect outcomes in patients undergoing M-TEER for functional mitral regurgitation?
p-value: p=<0.001
Significant racial and sex disparities exist in M-TEER outcomes for functional mitral regurgitation, highlighting the need for targeted efforts to improve equity in care.
Park et al. (2026) conducted a cohort in Functional mitral regurgitation. Female sex and Black race vs. Male sex and White race was evaluated on 30-day and 12-month all-cause and HF hospitalizations and mortality (p=<0.001). Black patients undergoing M-TEER for FMR had lower procedural success and higher 12-month HF readmission rates than White patients, while females had similar adjusted 1-year outcomes to males.
