Key result
Robotic ablation at 25 W for 60 s increased bipolar signal attenuation compared with manual ablation (52.4% vs 47.7%, P=0.01), with general anaesthesia providing additional benefits.

Does robotic catheter ablation improve catheter stability and bipolar voltage attenuation compared to manual ablation in patients undergoing AF ablation?
Absolute Event Rate: 52.4% vs 47.7%
p-value: p=0.01
Robotic assistance combined with general anaesthesia improves catheter stability and increases signal attenuation during AF ablation, potentially leading to more transmural lesions.
Malcolme‐Lawes et al. (2012) conducted an RCT in Atrial fibrillation (n=30). Robotic ablation vs. Manual ablation was evaluated on Signal attenuation during radiofrequency ablation (p=0.01). Robotic ablation at 25 W for 60 s increased bipolar signal attenuation compared with manual ablation (52.4% vs 47.7%, P=0.01), with general anaesthesia providing additional benefits.
