Summary
This study shows that permanent pacemaker implantation without fluoroscopy is feasible and safe, particularly for pregnant patients. Utilizing 3D mapping systems like Ensite NavX offers a reliable alternative to reduce radiation exposure.
Area of Science:
- Cardiology
- Medical Imaging
- Electrophysiology
Background:
- Fluoroscopy is standard for cardiac device implantation but poses radiation risks.
- Novel 3D mapping systems aid catheter navigation in electrophysiology.
- Limited data exists on 3D mapping for cardiac device implantation.
Purpose of the Study:
- To evaluate the feasibility and safety of permanent pacemaker implantation without fluoroscopy.
- To assess the efficacy of 3D mapping systems in zero-fluoroscopy procedures.
Main Methods:
- A retrospective study compared six patients undergoing zero-fluoroscopy pacemaker implantation with 20 controls using fluoroscopy.
- The Ensite NavX system was used for navigation in the zero-fluoroscopy group.
- Procedure times and complications were recorded for both groups.
Main Results:
- No complications occurred in either the zero-fluoroscopy or fluoroscopy groups.
- Pacemaker parameters were satisfactory in all patients.
- Dual-chamber pacemaker implantation took longer in the zero-fluoroscopy group (88.3 ± 19.6 min) compared to the fluoroscopy group (67.3 ± 7.6 min, P=0.013).
Conclusions:
- The Ensite NavX system provides a reliable and safe method for zero-fluoroscopy pacemaker implantation.
- This approach is suitable for specific patient populations, including pregnant women.
- It offers an alternative when fluoroscopy is unavailable or contraindicated.
