Which statement best describes the role of non-fluoroscopic mapping in EP procedures?

• A. It completely eliminates fluoroscopy in all cases.
• B. It increases contrast requirements due to additional imaging.
• C. It reduces reliance on fluoroscopy while maintaining imaging and mapping accuracy.
• D. It is only applicable to device interrogation.

Answer: (C)

Non-fluoroscopic mapping uses 3D electroanatomic mapping systems to guide catheter navigation and build detailed chamber maps without relying on continuous X-ray imaging. This approach lowers radiation exposure for both patient and staff while still providing precise visualization of anatomy and the timing and amplitude of electrical signals. In practice, fluoroscopy is often greatly reduced, and the mapping data lets you accurately localize critical structures and arrhythmia circuits to guide ablation. It isn’t about removing fluoroscopy entirely in every case; some procedures may still use limited fluoroscopy for safety checks or specific steps, but the overall reliance on X-ray is markedly decreased. It’s applied to mapping and ablation, not just device interrogation. That's why the statement describing reduced reliance on fluoroscopy while maintaining imaging and mapping accuracy best fits.
