Transseptal puncture without fluoroscopy using a radiofrequency needle: A case series.

Cardiol J 2020 Feb 10. Epub 2020 Feb 10.

Clinic for Electrophysiology, Herz- und Diabeteszentrum NRW, Ruhr-Universität Bochum, Bad Oeynhausen, Germany., Bad Oeynhausen, Germany.

Background: The non-fluoroscopy approach with the use of a three-dimensional (3D) navigation system is increasingly recognized as a future technology in the treatment of arrhythmias. However, there are a limited number of articles published concerning transseptal puncture without the use of fluoroscopy.

Methods: Presented in this paper is the first series of patients (n = 10) that have undergone transseptal puncture without the use of fluoroscopy under transesophageal echocardiography control using a radiofrequency transseptal needle and a 3D navigation system.

Results: All patients were treated without complications. In six patients, re-pulmonary vein isolation was performed. In 5 cases, linear ablation of the left atrium for treatment of left atrial macro re-entry tachycardia was provided. In 2 patients, focal atrial tachycardia was treated, 1 patient underwent cavo tricuspidal isthmus (CTI) ablation and one patient, re-CTI ablation. The ablation of complex fragmented atrial electrograms was done in 2 patients. In 1 case, right atrial macro re-entry tachycardia was treated.

Conclusions: Transseptal puncture without using fluoroscopy is safe and effective when using a radiofrequency needle, a 3D navigation system and transesophageal echocardiography.

Transseptal puncture for radiofrequency catheter ablations of left-sided arrhythmias in a paediatric population.

Cardiol Young 2017 Mar 18;27(2):267-272. Epub 2016 Apr 18.

1Department of Paediatric Cardiology,University Children's Hospital Zurich,Zürich,Switzerland.

Puncturing the atrial septum is frequently used in adults. In children, the transseptal puncture is less common, technically more demanding, and the rate of complications is not well described. We studied the feasibility and safety of this procedure in a retrospective analysis of 157 consecutive children undergoing transseptal puncture for radiofrequency catheter ablation of left atrial targets in two tertiary-care centres between 2005 and 2013.

Remote-controlled magnetic pulmonary vein isolation using a new three-dimensional non-fluoroscopic navigation system: a single-centre prospective study.

Arch Cardiovasc Dis 2013 Aug-Sep;106(8-9):423-32. Epub 2013 Jul 29.

Service de Cardiologie, Hôpital Nord, CHU de Saint-Étienne, Université Jean-Monnet, 42055 Saint-Étienne Cedex 2, France. Electronic address:

Background: Catheter ablation of atrial fibrillation (AF) focuses on pulmonary vein isolation (PVI), but the procedure is associated with significant X-ray exposure. Few data exist concerning the combination of remote magnetic navigation (RMN) and a new three-dimensional non-fluoroscopic navigation system (Carto(®) 3), which facilitates precise catheter navigation and limits X-ray exposure.

Aims: To assess the efficacy and extent of fluoroscopic exposure associated with the combination of RMN and the Carto 3 system in patients requiring AF ablation. Read More

Prospective comparison between conventional transseptal puncture and transseptal needle puncture with radiofrequency energy.

J Interv Card Electrophysiol 2011 Sep 19;31(3):237-42. Epub 2011 Apr 19.

Institut Universitaire de Cardiologie et Pneumologie de Québec, Quebec, QC, Canada.

Purpose: Patients undergoing left atrial ablation require transseptal puncture, which can be challenging, even for experienced physicians. This study compared the efficacy and safety of radiofrequency (RF) energy transseptal punctures to conventional approach.

Methods: Patients requiring transseptal puncture for left atrial access were included using either conventional approach or the NRG™ RF transseptal needle as first attempt. Read More
