  "abstract": "BACKGROUND: Disproportionate (d-) functional mitral regurgitation (FMR) is characterized by greater mitral regurgitation (MR) severity than expected from left ventricular (LV) dilatation. Morphological determinants of this imbalance remain unclear. METHODS AND RESULTS: /mL. CONCLUSIONS: Additional morphological factors were associated with greater MR severity beyond LV size and with residual MR after TEER, supporting a phenotype-based interpretation of FMR disproportionality.",
