Determinants and Prognostic Impact of Left Atrial Reservoir Strain Improvement Following Mitral Transcatheter Edge-To-Edge Repair.
Heart failure with functional mitral regurgitation (FMR) has poor prognosis, and mitral transcatheter edge-to-edge repair (M-TEER) is an effective treatment. However, patient responses are variable, highlighting the need for early markers of treatment success. Left atrial reservoir strain (LARS) reflects atrial complia...
