Catheter ablation of complex cardiac arrhythmias: Single-centre experience in Armed Forces.
Article in Medical journal, Armed Forces India, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundComplex arrhythmia ablation remains a technical challenge despite advances in hardware and mapping techniques. The aim of the study was to analyse the efficacy of radiofrequency ablation of arrhythmias requiring complex electrophysiological procedures at a tertiary-care centre.
methodsA retrospective study was done for catheter ablation of arrhythmias performed at a single centre from Aug 2012 to Nov 2016 (4 years 4 months). The standard ablation involved conventional catheters with antegrade right heart and retrograde left heart access. The procedure was considered complex, if it involved 3 D electro-anatomical (EA) guidance for mapping or required special hardware and/or trans-septal puncture.
resultsOf 333 electrophysiology (EP) cases 265 qualified for ablation. The cohort of arrhythmias requiring complex procedure (n = 94) comprised of supraventricular 15 (15.9%), atrioventricular 43 (44.7%) and ventricular 36 (38.3%). The procedure used three-dimensional EA mapping in 31; trans-septal puncture for left atrial access in 40; and use of special catheters and sheaths in all 94 procedures. The overall success in the complex group after the first procedure was 87.2% versus 88.3% (P < 0.05), and after redo procedure it was 90.4% vs 94.7% (P < 0.05). There were three complications (pericardial perforation: 2; cardioembolism: 1) only in the complex group. The fluoroscopy time for complex was longer than that of the standard procedure (25.10 ± 6.32 versus 15.23 ± 5.33 min, P = 2.54).
conclusionArrhythmias requiring complex electrophysiological procedure for ablation have a comparable success rate to standard ablation procedure but at the cost of extra hardware, complications and fluoroscopy time.
