Mitral valve replacement (MVR) preserving chordae significantly improved left ventricular function. Postoperative ejection fraction (EF) increased globally and regionally, demonstrating enhanced cardiac performance in patients with mitral regurgitation.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Medical Imaging

Context:

  • Mitral regurgitation necessitates surgical intervention, often mitral valve replacement (MVR).
  • The impact of chordae tendineae preservation during MVR on left ventricular (LV) function is a critical area of study.
  • Evaluating LV function requires precise imaging techniques like multigated equilibrium radionuclide angiography.

Purpose:

  • To assess the changes in left ventricular function following mitral valve replacement (MVR) with complete chordae tendineae preservation.
  • To quantify the improvement in global and regional ejection fraction (EF) after MVR surgery.
  • To determine the efficacy of preserving chordae tendineae in maintaining/improving cardiac performance.

Summary:

  • Fourteen patients with mitral regurgitation underwent MVR with all chordae tendineae preserved.

  • Preoperative and postoperative multigated equilibrium radionuclide angiography (SPECT) was used to measure global and regional LV ejection fraction (EF).
  • Results showed a significant increase in global EF (40.0% to 51.6%) and lateral wall regional EF (51.0% to 69.7%) post-MVR.

    • Impact:

    • Mitral valve replacement with chordae tendineae preservation leads to a remarkable improvement in left ventricular function.
    • This surgical technique offers a potential benefit for patients undergoing MVR, enhancing cardiac performance.
    • The findings support the consideration of chordae tendineae preservation in MVR procedures to optimize patient outcomes.
