Key result
SuperMap non-contact mapping was significantly faster than conventional contact mapping for generating diagnostic maps (394 vs. 611 seconds; P<0.0005) with similar accuracy (92% vs. 85%; P=0.4805).
Why the study?
SuperMap is a novel non-contact mapping algorithm for organized atrial arrhythmias, but its performance needed prospective evaluation and comparison against conventional high-density contact mapping.
Does the SuperMap non-contact charge density mapping algorithm reduce mapping time and improve accuracy compared to conventional contact mapping in patients with atrial tachycardias?
Observational (n=31)

The SuperMap non-contact charge density mapping algorithm provides a faster and reliable alternative to conventional contact mapping for guiding the ablation of complex atrial arrhythmias.
No takes yet. Share an insight, caveat, or question.
May shorten mapping time in atrial tachycardia ablation without accuracy loss; hypothesis-generating, needs randomized confirmation before practice change.
Pope et al. (2021) conducted an observational in Atrial tachycardias (n=31). SuperMap non-contact charge density mapping vs. Conventional high-density contact mapping was evaluated on Time taken to generate a diagnostic map (MD 217 s, 95% CI 116-318, p=< 0.0005). SuperMap non-contact mapping was significantly faster than conventional contact mapping for generating diagnostic maps (394 vs. 611 seconds; P<0.0005) with similar accuracy (92% vs. 85%; P=0.4805).
