Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - catheter ablation using magnetic navigation
Treatment: Devices - catheter ablation using manual navigation

Experimental: Magnetic navigation - Catheter ablation using magnetic navigation for ventricular tachycardia via remote magnetic navigation of a NaviStar RMT ThermoCool catheter, or other magnetically compatible catheter, via Stereotaxis's Niobe ES system.

Active comparator: Manual navigation - Catheter ablation using manual navigation for ventricular tachycardia via a manually navigated Thermocool catheter, or equivalent catheter.


Treatment: Devices: catheter ablation using magnetic navigation
elimination of cardiac arrhythmias through heating and destroying heart tissue with faulty electrical pathways through the use of Stereotaxis's Niobe ES System with the NaviStar RMT ThermoCool catheter or other magnetically compatible catheters.

Treatment: Devices: catheter ablation using manual navigation
elimination of cardiac arrhythmias through heating and destroying heart tissue with faulty electrical pathways through the use of the NaviStar ThermoCool catheter or other manually navigated catheters.
