Conclusions
ACCURESP™ RMA creates important error during automated RF annotation at
the LAPW, via delayed identification of deliberate and clinically
important catheter motion events. Previously identified auto-annotated
ablation targets using RMA “on” are likely to be importantly flawed,
and on-going RMA use represents an important impediment towards greater
reproducibility during PVI. In contrast, automated RF annotation with
RMA “off” demonstrated excellent catheter motion detection. We
therefore recommend avoiding RMA use during automated RF annotation
guided PVI.
