Summary
Simulation-based training using 3D-printed models improves technical skills in congenital heart surgery (CHS). This hands-on surgical training (HOST) enhances operative performance and patient outcomes, though wider adoption is needed.
Area of Science:
- Surgical Education
- Medical Simulation
- Congenital Heart Surgery
Background:
- Technical skill acquisition in congenital heart surgery (CHS) is hindered by limited hands-on operative experience.
- Simulation-based training, particularly using 3D-printed models, has emerged as a viable solution.
Purpose of the Study:
- To evaluate the effectiveness of simulation-based training using 3D-printed models in congenital heart surgery.
- To highlight the benefits of hands-on surgical training (HOST) for improving surgical skills and patient outcomes.
Main Methods:
- Development and refinement of 3D-printed models for hands-on surgical training (HOST) since 2015.
- Utilizing advanced models with realistic valvar/subvalvar apparatus and tissue-mimicking materials.
- Assessing the impact of deliberate, regular simulation practice on surgical technical skills.
Main Results:
- Simulation practice demonstrably improves surgeons' technical skills across the spectrum of CHS.
- Trainees successfully translate improved simulation performance to the operative environment.
- Enhanced simulation training correlates with improved patient outcomes.
Conclusions:
- Simulation-based training, especially with advanced 3D models, is effective for developing CHS technical skills.
- Despite proven benefits, widespread adoption in training curricula is limited by factors like funding and access.
- Training programs should integrate simulation methods as a routine component of CHS education.
