Left atrial anterior line ablation using ablation index and inter-lesion distance measurement.
Article in Clinical research in cardiology : official journal of the German Cardiac Society, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
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
backgroundAblation index (AI) is a novel ablation quality marker that incorporates contact force (CF), time and power in a weighted formula to provide accurate information about lesion formation during catheter ablation. This index has been evaluated for pulmonary vein isolation (PVI) but has not been systematically used for other left atrial (LA) procedures so far. The aim of this study is to evaluate the feasibility and efficacy of this index for LA anterior line (AL) ablation (LAALA).
methods30 consecutive patients with persistent atrial fibrillation or LA macro-reentrant tachycardia and large low-voltage area at the left atrial anterior wall were evaluated and divided into 2 groups: group 1 (15 pts) LAALA guided by CF; group 2 (15 pts) LAALA guided by AI target (500) and inter-lesion distance ≤ 6 mm.
resultsIn group 2, shorter ablation time (12.5 ± 3.8 vs 17 ± 7 min, p = 0.049), overall RF application time (7.9 ± 1.4 vs 10.8 ± 3.2 min. p = 0.01) and less radiofrequency (RF) applications (14.5 ± 2.3 vs 20.5 ± 6.1 p = 0.01) were necessary to achieve AL bi-directional block. Acute reconnection of the AL was documented in three patients (20%) of group 1 and in no patient of group 2 (20% vs 0% p = 0.22). At site of reconnection, an inter-lesion distance > 6 mm was always found. There was no difference in terms of CF and power between group 2 and group 1. AI was statistically different between group 2 and group 1 (AI = 511 ± 77 vs 451 ± 111; p = 0.004).
conclusionAI-guided LAALA in this study was feasible and featured by shorter ablation time, shorter overall RF application time and a reduced number of RF applications to achieve AL bidirectional block.
