Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology
  • Biomedical Engineering

Background:

  • Percutaneous treatments for valve disease emerged as an alternative to open surgery in the 1980s.
  • Balloon valvuloplasty is a viable option for rheumatic mitral stenosis and congenital pulmonary stenosis.
  • Feasibility of percutaneous valve implantation was demonstrated in vitro and in vivo starting in the mid-1990s.

Purpose of the Study:

  • To review the evolution and current status of percutaneous valve treatment.
  • To identify the limitations and challenges associated with transcatheter valve implantation.
  • To discuss the potential benefits of percutaneous valve replacement compared to surgical approaches.

Main Methods:

  • Review of in vitro and in vivo studies on percutaneous catheter-based valve implantation.

Related Experiment Videos

  • Analysis of limitations including embolization, deployment difficulties, stent migration, paravalvular leakage, and durability.
  • Comparison of percutaneous approaches with traditional open surgical valve repair and replacement.

    • Main Results:

    • Transcatheter valve implantation has progressed from in vitro feasibility to in vivo application.
    • Significant limitations persist, hindering percutaneous techniques from becoming a definitive alternative to surgery.
    • Open surgical valve repair and replacement remain the gold standard for heart valve disease treatment.

    Conclusions:

    • Percutaneous valve replacement offers potential advantages such as reduced surgical risk, less invasiveness, and shorter rehabilitation.
    • Economic benefits include shorter hospital stays and overall cost reduction.
    • Further research and technological advancements are necessary to overcome current limitations and establish percutaneous valve procedures as a safe and reliable therapeutic option.
