Area of Science:

  • Medical Education
  • Surgical Simulation
  • Cardiothoracic Surgery Training

Background:

  • Surgical simulation is crucial for developing surgeon competency in a low-stress environment.
  • Existing cardiothoracic procedure simulations face limitations due to cost and material availability.
  • Effective training requires hands-on engagement to improve skill, retention, and competency.

Purpose of the Study:

  • To develop a low-cost, reproducible surgical simulation for teaching aortic valve replacement (AVR).
  • To provide preclinical medical students with a comprehensive wet laboratory experience in AVR.
  • To emphasize fundamental surgical skills, teamwork, and communication in a simulated surgical setting.

Main Methods:

  • A single-center educational workshop design was employed.
  • A wet laboratory experience utilized porcine hearts for aortic valve replacement simulation.
  • Simulated valves were constructed using insulation foaming and aluminum wiring.

Main Results:

  • Thirty-eight preclinical medical students participated in the simulation workshop.
  • The simulation provided a step-by-step procedural overview of AVR.
  • Trainees learned technical skills adaptable to their proficiency level, including suturing and knot tying.

Conclusions:

  • A low-cost, reproducible surgical simulation for AVR using porcine models is feasible.
  • This simulation enhances surgical skill acquisition and competency in resource-limited institutions.
  • The simulation effectively teaches fundamental surgical principles and teamwork in a practical setting.
