Key result
Remote retrograde transaortic RF ablation of left-sided accessory pathways using a magnetic navigation system is feasible and safe, with acute success rates of 80% for Celsius RMT and 60% for Helios II.

Should not yet change practice for left-sided pathways; leaves open efficacy in prospective trials.
Observational (n=20)
Is remote retrograde transaortic RF ablation using a magnetic navigation system feasible and safe for left-sided accessory pathways?
Absolute Event Rate: 80% vs 60%
Remote retrograde transaortic RF ablation of left-sided accessory pathways using magnetic navigation is feasible, safe, and reduces physician fluoroscopy exposure, though it has a steep learning curve.
Thornton et al. (2007) conducted an observational in Left-sided accessory pathways (n=20). Remote retrograde transaortic RF ablation using a magnetic navigation system vs. Helios II vs Celsius RMT catheters was evaluated on Acute ablation success. Remote retrograde transaortic RF ablation of left-sided accessory pathways using a magnetic navigation system is feasible and safe, with acute success rates of 80% for Celsius RMT and 60% for Helios II.
