Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Previous studies have evaluated the feasibility and safety of radiofrequency (RF) energy applied to a conventional needle as a technique to access the left atrium, particularly in patients with a repeat procedure, fibrotic septum or aneurysmal septum.5, 6 As a result of this earlier work, a special proprietary device has been designed. The NRG RF needle (Baylis Medical Inc., Montreal, Canada), uses radiofrequency energy emitted from the needle tip to aid in transseptal access. Despite limited literature to support its superiority and safety7-9compared to the conventional approach, the new device has become adopted in some electrophysiology procedures involving a transseptal puncture.
