An integrated system for real-time image guided cardiac catheter ablation

Area of Science:

• Medical Imaging
• Cardiac Electrophysiology
• Surgical Technology

Background:

• Minimally invasive cardiac catheter ablation demands precise visualization of cardiac anatomy and electrophysiology (EP).
• Current visualization methods include fluoroscopy, ultrasound, and basic 3D models, lacking patient-specific detail.
• Integrating detailed, patient-specific anatomical data is a growing area of interest in cardiac ablation.

Purpose of the Study:

• To develop and evaluate a prototype system for cardiac ablation that integrates patient-specific preoperative data.
• To fuse multiple visualization modalities (fluoroscopy, ultrasound, EP) into a single display for improved procedural guidance.
• To demonstrate the registration and visualization of catheter positions within a preoperative cardiac model.

Main Methods:

• Developed a prototype system framework with an efficient communication protocol for integrating diverse components.
• Utilized a two-chamber cardiac phantom to test the system's capabilities.
• Implemented registration and visualization techniques for tracked catheter points within the phantom's preoperative model.

Main Results:

• Successfully demonstrated the integration of patient-specific preoperative data into a simulated ablation procedure.
• Showcased the ability to visualize tracked catheter points accurately within the cardiac phantom's model.
• Validated the framework for fusing multiple visualization modalities into a unified display.

Conclusions:

• The prototype system effectively integrates patient-specific anatomical data and fuses visualization modalities for cardiac ablation.
• This approach has the potential to enhance the precision and effectiveness of minimally invasive cardiac procedures.
• Further development and validation are warranted for clinical application in electrophysiology (EP) interventions.
