Area of Science:

  • Cardiovascular Surgery
  • Surgical Education
  • Medical Device Development

Background:

  • Aortic root surgery training is challenged by procedural complexity and intricate 3D anatomy.
  • Existing training methods may be costly and lack accessibility for residents and junior surgeons.

Purpose of the Study:

  • To develop and evaluate a low-cost, reusable, and portable middle-fidelity simulator for aortic root surgery training.
  • To assess the simulator's effectiveness in improving surgical skills and reducing training costs.

Main Methods:

  • A self-made, portable aortic root simulator was constructed using silicone for realistic tissue properties.
  • The simulator was used to practice various aortic root procedures, including valve replacements and repairs.
  • The cost-effectiveness of the simulator was calculated.

Main Results:

  • The silicone-based simulator accurately replicated aortic root anatomy and properties, allowing unlimited practice.
  • It facilitated training for diverse aortic valve replacements, root procedures (enlargement, remodeling, reimplantation, replacement), and valve repair techniques.
  • The total construction cost was approximately €1.

Conclusions:

  • A middle-fidelity simulator can significantly improve surgical skills in aortic root operations.
  • This low-cost, portable simulator offers a cost-effective solution for training, potentially reducing operative time.
  • The simulator provides a valuable tool for enhancing surgical proficiency in complex aortic procedures.
