    Posterior left ventricular wall rupture is a rare but fatal complication after mitral valve replacement (MVR). Surgical repair strategies depend on rupture type, emphasizing prevention through modified techniques and leaflet retention.

    Area of Science:

    • Cardiac Surgery
    • Cardiovascular Research
    • Surgical Complications

    Context:

    • Posterior left ventricular wall rupture is an uncommon yet frequently lethal complication following mitral valve replacement (MVR).
    • The incidence of this severe complication is approximately 1% of all MVR procedures.
    • Ruptures are often linked to surgical technique, including mechanical stress during operation or leaflet removal.

    Purpose:

    • To outline the causes, incidence, and management strategies for posterior left ventricular wall rupture post-mitral valve replacement.
    • To differentiate surgical approaches based on rupture classification (Type 1, 2, or 3).
    • To highlight preventive measures to mitigate the risk of this complication.

    Summary:

    • Most ruptures result from technical errors during surgery or tissue damage from mitral valve leaflet removal.

  • Surgical repair necessitates cardiopulmonary bypass.
  • Extracardiac approaches are recommended for Type 2 or 3 ruptures, while Type 1 ruptures are best managed with an intracardiac approach.

    • Impact:

    • Effective surgical repair strategies can improve outcomes for a life-threatening complication.
    • Understanding causative factors allows for refinement of surgical techniques to enhance patient safety.
    • Preventive measures, such as modifying operative techniques and managing ventricular loading conditions, are crucial.
