Key result
Non-white race is linked to ~46% higher 1-year mortality or HF hospitalization after mitral TEER.
Why the study?
Data regarding the clinical course following mitral transcatheter edge-to-edge repair across different racial groups are scarce.
Population
964 patients undergoing mitral TEER for MR
Comparison
Outcomes compared across racial groups (whites, blacks, Asians, and Hispanics)
Design
Single-center retrospective analysis
Follow-up
1-year

Black and non-white patients may warrant closer post-TEER surveillance in functional MR; leaves open independent racial effects beyond baseline differences.

Absolute Event Rate: 32.9% vs 22.5%

Significant racial disparities exist in baseline characteristics and 1-year outcomes following mitral TEER, with black patients experiencing higher rates of heart failure hospitalizations and mortality, particularly in functional MR.
Shechter et al. (2023) conducted an observational in Mitral regurgitation (n=964). Non-white race vs. White race was evaluated on Composite of all-cause mortality or heart failure hospitalizations at 1 year (p=0.002). Non-white patients undergoing mitral transcatheter edge-to-edge repair had a significantly higher 1-year incidence of mortality or heart failure hospitalizations compared to white patients (32.9% vs. 22.5%).
