Autopsy reviews 20 deaths after percutaneous balloon mitral valvotomy (PBMV). Complications like cardiac tamponade and mitral valve damage were common, especially in salvage cases.

Area of Science:

  • Cardiology
  • Pathology
  • Interventional Cardiology

Background:

  • Percutaneous balloon mitral valvotomy (PBMV) is a procedure to treat mitral stenosis.
  • Understanding post-procedural autopsy findings is crucial for improving patient outcomes.

Purpose of the Study:

  • To report autopsy findings in patients who died following PBMV.
  • To identify complications and contributing factors to mortality after PBMV.

Main Methods:

  • Retrospective analysis of autopsy findings in 20 patients who died after PBMV.
  • Review of procedural details and clinical history for 508 attempted PBMV cases.

Main Results:

  • Mortality occurred in 20 patients, with 17 undergoing PBMV as a salvage procedure.

  • Common autopsy findings included interatrial septostomy defects (19/20), mitral valve thickening/calcification (16/20).
  • Fatal complications included cardiac tamponade (5 cases), mitral valve damage (5 cases), and late infective endocarditis.

    • Conclusions:

    • PBMV, particularly as a salvage procedure, carries significant mortality risks.
    • Cardiac tamponade and mitral valve damage are key complications.
    • Interatrial septostomy defects are a common procedural artifact requiring attention.
