Expanding Applications of Three-Dimensional Cardiac Mapping Systems: A Review

Area of Science:

• Cardiovascular Medicine
• Medical Imaging
• Interventional Cardiology

Background:

• Percutaneous coronary intervention (PCI) is a standard treatment for coronary artery disease.
• Current PCI methods rely on fluoroscopy and iodinated contrast, posing risks of radiation exposure and nephrotoxicity.
• There is a growing need for advanced imaging techniques to minimize these risks.

Purpose of the Study:

• To review the current evidence on electro-anatomical mapping systems (EAMS) for coronary intervention.
• To outline the technical principles and applications of EAMS in PCI.
• To explore the potential of EAMS to reduce fluoroscopy and contrast use in PCI.

Main Methods:

• Review of existing literature on EAMS in cardiovascular interventions.
• Analysis of technical principles enabling EAMS-based coronary visualization.
• Examination of studies demonstrating feasibility and safety in device implantation and PCI.

Main Results:

• EAMS can provide real-time 3D visualization of coronary anatomy and interventional tools.
• Coronary guidewires can be adapted as electrodes for EAMS.
• Early studies indicate feasibility and safety, with potential to mitigate radiation and contrast exposure.

Conclusions:

• EAMS show promise as an alternative imaging modality for PCI.
• This technology may reduce patient and operator exposure to radiation and nephrotoxic contrast agents.
• Further research is warranted to establish the full role of EAMS in coronary intervention.
