Imaging Real-Time Coronary Anatomy Using a Three-Dimensional Electrophysiology Mapping System

Area of Science:

• Cardiovascular Imaging
• Medical Device Development
• Electrophysiology

Background:

• Accurate 3D mapping of coronary arteries is crucial for interventional procedures.
• Existing methods for coronary anatomy reconstruction can be time-consuming.
• Development of novel tools for real-time tracking and mapping is needed.

Purpose of the Study:

• To assess the feasibility of rapid 3D coronary artery mapping using electroanatomical mapping systems (EAMS).
• To develop and evaluate a bipolar coronary guidewire for accurate in vitro localization.
• To determine the precision of the bipolar guidewire within a 3D coronary model.

Main Methods:

• Utilized EnSite Precision system for 3D coronary anatomy reconstruction in five patients.
• Developed a water bath model with a 3D-printed coronary artery structure.
• Tested the performance and localization accuracy of a bipolar coronary guidewire in the in vitro model.

Main Results:

• Achieved successful guidewire localization and 3D coronary anatomy reconstruction in all cases.
• Demonstrated excellent localization accuracy of the bipolar guidewire's distal tip in the water bath model.
• Collected point cloud data effectively with the bipolar guidewire.

Conclusions:

• Electroanatomical mapping systems (EAMS) are feasible and safe for collecting coronary anatomy data.
• Real-time tracking with a bipolar catheter shows high accuracy in vitro.
• The developed bipolar guidewire shows promise for accurate coronary interventions.
