The prevalence and characteristics of candidates for percutaneous left atrial appendage occlusion using a WATCHMAN device among patients who underwent atrial fibrillation ablation in a Japanese population.

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
backgroundPercutaneous left atrial appendage occlusion (LAAO) using a WATCHMAN device could be a treatment option for patients with non-valvular atrial fibrillation (AF) with thromboembolic and bleeding risk. We sought to determine the prevalence and characteristics of patients with AF ablation who are potential candidates for WATCHMAN implantation in a Japanese population.
methodsWe enrolled 2443 consecutive patients who had previously undergone AF ablation and transesophageal echocardiography (TEE). We assessed their clinical characteristics and measured their LAA orifice diameter and depth retrospectively using the obtained TEE images. We defined patients who met both anatomical criteria (LAA orifice max diameter: 17-31 mm and LAA max depth > LAA orifice max diameter) and clinical criteria (CHA
resultsAmong the 2443 enrolled patients, 361 (15%) met the clinical criteria, and 1928 (79%) met the anatomical criteria. Thus 12% (293/2443) of the total patient group met the criteria of LAAO candidates. LAAO candidates showed larger left atrial (LA) volume (77.6 ± 30.1 vs. 67.7 ± 29.1 mL, P < 0.001), larger LAA orifice diameter (22.5 ± 3.2 vs. 22.0 ± 4.3 mm, P = 0.026), and larger LAA depth (28.9 ± 4.6 vs. 27.0 ± 4.8 mm, P < 0.001). LAAO candidates made up only 23% of patients with CHA
conclusionTwelve percent of patients who underwent AF ablation were potential candidates for LAAO using a WATCHMAN device in this Japanese population. It is imperative to evaluate bleeding risk when considering the indications for LAAO.
