Key result
Temperature-controlled cooled-tip radiofrequency linear ablation guided by a realtime position management system successfully created a transmural linear ablation line without thrombus in 4 of 9 pigs.
Why the study?
Does temperature-controlled cooled-tip radiofrequency linear ablation guided by a realtime position management system create transmural linear lesions without thrombus formation in a porcine model?
Does temperature-controlled cooled-tip radiofrequency linear ablation guided by a realtime position management system create transmural linear lesions without thrombus formation in a porcine model?
Temperature-controlled cooled-tip RF linear ablation guided by a realtime position management system demonstrates potential for creating transmural linear lesions in the atria without thrombus formation in a porcine model.

May support further preclinical testing; hypothesis-generating for human AF ablation and should not change practice.
Watanabe et al. (2011) studied Atrial fibrillation (experimental model) (n=9). Temperature-controlled cooled-tip radiofrequency linear ablation guided by RPM was evaluated on Creation of a transmural linear ablation line (grade 1 lesion). Temperature-controlled cooled-tip radiofrequency linear ablation guided by a realtime position management system successfully created a transmural linear ablation line without thrombus in 4 of 9 pigs.
