A novel pace-mapping technique for Isthmus Identification in Non-Sustained Uncommon Atrial Flutter Pacing Technique: the INPACT method-a case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Mapping uncommon atrial flutter (AFL) remains challenging when tachycardia cannot be sustained during the procedure. We developed a novel pace-mapping methodology for identifying critical isthmuses in non-sustained uncommon AFL circuits during sinus rhythm. Case summary: A 70-year-old male presented with persistent AFL (cycle length 370 ms) following mitral valve repair with concomitant surgical pulmonary vein isolation. During electrophysiological study, the tachycardia terminated spontaneously, precluding conventional mapping. We implemented the Isthmus Identification in Non-Sustained Uncommon Atrial Flutter PACing Technique (INPACT), combining Intracardiac Pattern-match ScOring (iPASO) technology with systematic pace-mapping during sinus rhythm. A novel isthmus ratio (IR) metric differentiated potential isthmus sites among those with high morphological correlation (iPASO ≥90%). The critical isthmus was identified within a low-voltage area adjacent to the atrial septotomy line. Radiofrequency ablation targeting the site with the highest IR value eliminated the tachycardia with no recurrence at 6-month follow-up. Discussion: The INPACT enables identification of critical isthmuses without requiring sustained tachycardia, offering a solution for challenging cases where conventional mapping is limited by non-sustained arrhythmia. This approach may improve procedural efficiency and outcomes in complex uncommon AFL.
