1 · What the graph read from it

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.

2 · The registry

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

aimsNanosecond pulsed field ablation (nsPFA) has emerged as an alternative in atrial fibrillation (AF) ablation. It leverages the alleviated muscle contractions (MCs) associated with nanosecond pulses, which may reduce complications and anaesthetic requirements compared with conventional microsecond PFA (μsPFA). To pre-clinically compare the safety, efficacy, and MC effects of nsPFA and μsPFA. METHODS AND

resultsTypical parameters were tested for pulmonary vein isolation (PVI) in swine using a novel commercial PFA system with either nsPFA or μsPFA protocols. Procedural outcomes and histological analysis were evaluated at 3-, 30-, and 90-day follow-ups. Electrical stimulation experiments were conducted using various pulse voltages and widths (ranging from nanoseconds to microseconds) to evaluate contractions in swine. nsPFA was non-inferior to μsPFA in terms of PVI safety and efficacy in the follow-up of 18 swine ablation procedures. Both protocols achieved consistent transmural and circumferential lesion creation without damaging adjacent structures such as the oesophagus or causing phrenic nerve block or paralysis. Additionally, nsPFA induced significantly lower MCs than μsPFA did in swine.

conclusionThe nsPFA protocol is a demonstrated potential approach for AF ablation, demonstrating comparable safety and efficacy to μsPFA, with reduced MCs. These findings suggest that nsPFA may offer an equally effective alternative, with significantly reduced MCs, which may translate to lower anaesthesia requirements.
