The PRECEPT Prospective, Multicenter, Nonrandomized Study

Persistent atrial fibrillation ablation with contact Force-Sensing catheter: The prospective multicenter PRECEPT trial

Mansour M, et al. JACC Clin Electrophysiol. 2020;6(8):958-969.

PRECEPT evaluated the safety/effectiveness of persistent atrial fibrillation ablation with contact force-sensing THERMOCOOL SMARTTOUCH® SF Catheter and CARTO VISITAG™ Module using a tailored PVI-only/PVI+ approach. 80% of patients experienced clinical success at 15 months.

ICE Meta-Analysis

The Use of Intracardiac Echocardiography (ICE) Catheters in Endocardial Ablation of Cardiac Arrhythmia: Meta-Analysis of Efficiency, Effectiveness, and Safety Outcomes​

Goya M, et al. J Cardiovasc Electrophysiol. 2020;31(3):664-673.

A systematic literature review and meta-analysis of 19 studies compared outcomes of cardiac arrythmia ablations performed with and without the use of ICE.​

Use of ICE was associated with a significant:​

  • 6.95 mean reduction in fluoroscopy time​
  • 15.2 mean reduction in procedure time
  • Reduction in fluoroscopy dose

Cardiac Perforation With Catheter Ablation

Predictors of Cardiac Perforation With Catheter Ablation of Atrial Fibrillation

Friedman DJ, et al. JACC Clin Electrophysiol. 2020;6(6):636-645.

This retrospective, observational cohort study identified factors associated with cardiac perforation occurrence during catheter ablation for atrial fibrillation.

Cardiac perforation predictors:

  • 1.3× greater odds of perforation for female sex
  • 1.4× greater odds of perforation for obesity
  • 4.9× lower odds of perforation with use of ICE
  • 0.1× lower odds of perforation with prior cardiac surgery

The multicenter, nonrandomized SMART SF evaluated the safety and efficiency of the THERMOCOOL SMARTTOUCH® SF Catheter with CARTO VISITAG™ Module for symptomatic, drug refractory paroxysmal atrial fibrillation.

SMART SF study outcomes:

  • 96.2% acute procedural effectiveness
  • 2.5% primary adverse event rate
  • 74.9% freedom from recurrence at 12-months

Atrioesophageal Fistula Safety

Comparing Rates of Atrioesophageal Fistula With Contact Force-Sensing and Non-Contact Force-Sensing Catheters: Analysis of Post-Market Safety Surveillance Data

Calkins H, et al. J Interv Card Electrophysiol. 2020;59(1):49-55.

A retrospective data analysis determined atrioesophageal fistula rates associated with the use of contact force-sensing and non-contact force-sensing catheters.

Retrospective analysis outcomes:

  • Contact force-sensing catheters were used 2 to 5 times more frequently in left atrial procedures
  • Atrioesophageal fistula rates: 0.006% for contact force-sensing catheters versus 0.005% for non-contact force-sensing catheters
  • Atrioesophageal fistula events are associated with the use of high power, high force, and long radiofrequency duration

In the US, THERMOCOOL® Navigation Catheters are indicated for the treatment of drug refractory recurrent symptomatic paroxysmal atrial fibrillation, when used with CARTO® 3 Systems (excluding NAVISTAR® RMT THERMOCOOL® Catheter).

The THERMOCOOL SMARTOUCH® SF Catheter is indicated for drug refractory recurrent symptomatic persistent atrial fibrillation (AF) (continuous AF >7 days but <1 year), refractory or intolerant to at least 1 Class I or III AAD, when used with the CARTO® 3 System.

The CARTO VISITAG™ Module provides access to data collected during the application of RF energy. The data does not indicate the effectiveness of RF energy application. CARTO VISITAG™ Module settings are user defined based on the user’s clinical experience and medical judgment. Biosense Webster, Inc. does not recommend any settings for the CARTO VISITAG™ Module.
