Background:

Radiofrequency (RF) ablation demands extensive electrophysiological expertise and physics knowledge.
Existing training methods may not adequately prepare practitioners for the complexities of RF ablation procedures.
A need exists for a standardized, hands-on system to teach RF ablation principles and techniques.

Approach:

Developed six workstations with computer-controlled RF ablation generators and universal connection boxes.
Created specialized wet labs with saline basins, thermostats, and pumps to simulate physiological conditions, including blood flow.
Designed the system for hands-on training, enabling exploration of various ablation parameters and their effects.

Key Points:

The system facilitates demonstration of lesion formation variations based on electrode design, sensor technology, and ablation strategies.
It highlights the impact of simulated blood flow and electrode angulation on myocardial lesion characteristics.
The teaching system proved effective in replicating industrial in-vitro testing protocols.

Conclusions:

The established in-vitro teaching system provides a valuable platform for RF ablation education and skill development.
It allows for systematic investigation of factors influencing ablation outcomes in a controlled environment.
This system supports both trainee education and the validation of ablation technologies.
