This large series of 382 consecutive cases demonstrated the safety and effectiveness of fluoroless TSP and RF ablation using 3D electroanatomic mapping (EAM).
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 TSP and RF ablation using 3D 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
