Publication summaries
July 2020, Sanchez et al., published in Journal of Cardiovascular Electrophysiology
This analysis compared the cost-effectiveness of a mechanical needle to an RF device during pulmonary vein isolation (PVI) procedures in three clinical scenarios.
April 2020, Salam et al., published in Journal of Innovations in Cardiac Rhythm Management
This large series of 382 consecutive cases demonstrated the safety and effectiveness of fluoroless transseptal puncture (TSP) and radiofrequency (RF) ablation using 3D electroanatomic mapping (EAM).
April 2018, Tokuda et al., published in Heart and Vessels
This retrospective, propensity score-matched analysis of 232 patients who underwent a catheter ablation procedure for atrial fibrillation compared transseptal punctures performed with a RF transseptal needle to those with a mechanical transseptal needle.
March 2017, Razminia et al., published in Pacing and Clinical Electrophysiology
This five-year retrospective analysis examined 500 consecutive patients who underwent fluoroless cardiac catheter ablation from December 2010 to March 2016.
September 2013, Hsu et al., published in Journal of the American Heart Association
Randomized, prospective, and controlled trial. The study included 72 patients randomized to either the NRG Transseptal Needle or a conventional transseptal needle on a 1:1 basis.
March 2013, Winkle et al., published in Journal of Interventional Cardiac Electrophysiology
This study evaluated the cost-per-procedure used to perform an atrial fibrillation ablation.
September 2011, Winkle et al., published in Heart Rhythm
This large case series compared the safety and efficacy of TSP using the purpose-built RF NRG Transseptal Needle to a sharp mechanical needle for atrial septal puncture.
