Universal Method of Compatibility Assessment for Novel Ablation Technologies With Different 3D Navigation Systems

Area of Science:

• Medical Devices
• Electrophysiology
• Catheter Ablation

Background:

• Incompatibility between different manufacturers' ablation and mapping systems presents a clinical challenge.
• Devices are often used together despite lacking out-of-the-box cross-compatibility.
• A need exists for standardized compatibility testing methods.

Purpose of the Study:

• To develop a bench-testing method for assessing compatibility.
• To evaluate the compatibility between the DiamondTemp ablation system (DTA) and the Rhythmia electroanatomic mapping system (EAM).

Main Methods:

• Tested multiple connection configurations between DTA and Rhythmia EAM.
• Utilized Ensite EPT GenConnect box (GCB) and Rhythmia Maestro GCB (native setup).
• Evaluated alternative Medtronic GCB-E configurations.

Main Results:

• Real-time tracking of DTA on Rhythmia EAM was achieved in all tested setups.
• Configuration 3.1 showed an initial shift after the first radiofrequency (RF) application.
• Configuration 3.2 demonstrated no significant shift, while configuration 3.3 showed a massive positional shift.

Conclusions:

• A universal and reproducible compatibility testing method was established.
• DTA demonstrated satisfactory compatibility with Rhythmia EAM under a specific configuration.
• The findings highlight the importance of specific setup configurations for device compatibility.
