Safety and effectiveness of a novel fluoroless transseptal puncture technique for lead-free catheter ablation: A case series

Faster, zero-fluoroscopy transseptal puncture (TSP) time*

The NRG™ Transseptal Needle offered a faster, fluoroless transseptal puncture technique for catheter ablation compared to a mechanical needle.*

Key takeaways

Achieved single or double TSP 100% successfully without fluoroscopy within 28±15 min

Observed total procedure time of 135±34 minutes without any significant complications

Faster, fluoroless transseptal time

In this retrospective study of 382 cases, the RF NRG Transseptal Needle enabled zero-fluoroscopy transseptal access via first TSP within 27.8±15.1 min of initial venous access.1 This is comparable to times seen with fluoroscopy-guided RF transseptal puncture, which showed improvement relative to the use of conventional mechanical needles with fluoroscopy (36.4±17.7 min).*, 2

The RF NRG Transseptal Needle enabled a faster and fluoroless transseptal puncture time.

100% TSP success rate

Using the dedicated RF NRG Transseptal Needle, single and double TSP were achieved with 100% success without any fluoroscopy, regardless of septal anatomy or history of prior transseptal catheterization.

Using the RF NRG Transseptal Needle technique, 100% of attempted TSP were achieved successfully without any fluoroscopy.
