    Transcatheter edge-to-edge mitral valve repair (M-TEER) is recommended for patients with severe secondary ventricular mitral regurgitation at high surgical risk.

  • 2

    Forward stroke volume (FSV) may serve as a more accurate marker for assessing left ventricular dysfunction compared to left ventricular ejection fraction (LVEF).

  • 3

    Atrial mitral regurgitation (MR) is increasingly recognized as a distinct phenotype, often occurring in patients with preserved left ventricular function.

  • 4

    The study investigated the early effects of M-TEER on FSV and its predictive value for outcomes like all-cause mortality and heart failure hospitalization.

  • 5

    Echocardiographic assessments were performed at baseline and 4 weeks post-M-TEER to evaluate MR severity and left ventricular function.
