Mitral valve replacement impacts left ventricular geometry, causing axis lengthening and reduced function, particularly in mitral insufficiency patients. However, some wall motion abnormalities improve over time.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Echocardiography

Background:

  • Mitral stenosis and insufficiency affect left ventricular (LV) geometry and function.
  • Mitral valve replacement (MVR) is a common surgical intervention.
  • Understanding postoperative LV changes is crucial for patient outcomes.

Purpose of the Study:

  • To assess changes in LV geometry and function after MVR in patients with mitral stenosis (MS) and mitral insufficiency (MI).
  • To evaluate the impact of subvalvular apparatus discontinuity on LV mechanics post-MVR.

Main Methods:

  • Transthoracic (TTE) and transesophageal (TEE) echocardiography were used.
  • LV geometry and function were assessed preoperatively and postoperatively (early and late) in 40 patients (20 MS, 20 MI).

  • Subvalvular apparatus continuity was evaluated.

    • Main Results:

    • LV longitudinal axis lengthened significantly post-MVR in both MS and MI groups.
    • Area ejection fraction (AEF) showed no significant change in MS but decreased in MI.
    • LV ejection fraction (EF) decreased significantly in MI patients, with new postoperative hypokinesis observed in both groups, particularly in septal segments.

    Conclusions:

    • MVR alters LV geometry, leading to axis lengthening and potential functional impairment, especially in MI.
    • Subvalvular apparatus discontinuity may contribute to observed geometric changes.
    • Postoperative hypokinesis often resolves by late follow-up.
