    Two patients with prosthetic valve dysfunction experienced acute mitral regurgitation. Emergency surgery was successful in both cases, highlighting the need for prompt intervention in prosthetic heart valve complications.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Biomedical Engineering

    Background:

    • Prosthetic heart valves are crucial for treating valvular heart disease.
    • Prosthetic valve dysfunction can lead to severe hemodynamic compromise.
    • Timely diagnosis and intervention are critical for patient outcomes.

    Observation:

    • Two cases of prosthetic valve dysfunction presented with acute massive mitral regurgitation.
    • One case involved complete dislodgement of a disc valve occluder, a rare event.
    • Both patients experienced sudden cardiac decompensation.

    Findings:

    • Emergency surgical intervention was successful in both reported cases.
    • Survival after complete prosthetic valve occluder dislodgement was achieved.

  • Diagnosis of acute decompensation in patients with prosthetic valves can be challenging.

    • Implications:

    • Urgent surgical operation is vital for patients with prosthetic valve dysfunction and acute mitral regurgitation.
    • This report highlights a previously undocumented complication of disc valve prostheses.
    • Improved diagnostic strategies may be needed for cardiac decompensation in prosthetic valve patients.
