Value of echocardiography in evaluating efficacy of radiofrequency catheter ablation in patients with atrial fibrillation.
Article in American journal of translational research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
objectiveTo analyze the cardiac structure and function of patients with recurrent atrial fibrillation (AF) after radiofrequency catheter ablation (RFCA) with echocardiography and to predict the factors affecting recurrence.
methodsIn this retrospective study, 87 patients who received RFCA for AF in the Weihai Municipal Hospital from June 2018 to December 2019 were enrolled. According to the recovery of postoperative sinus rhythm (SR), patients with recovered SR were assigned to the research group (Res group, n=60), while those with AF recurrence were included in the control group (Con group, n=27). The transthoracic echocardiography was adopted to measure the changes of left atrium-related parameters of patients before RFCA and at 6 months after surgery, and the transesophageal three-dimensional echocardiography was adopted for measuring the changes of left atrial appendage (LAA)-related parameters. In addition, multivariate logistic regression was performed to analyze the factors influencing postoperative recurrence of AF.
resultsAfter 6-month follow up, SR was restored in 60 cases and AF recurred in 27 cases. After surgery, the left atrial anteroposterior diameter (LAAPD), left atrial left and right diameter (LALRD), left atrial up and down diameter (LAUDD), maximum volume of left atrium (LAVmax), minimum volume of left atrium (LAVmin), opening diameter of LAA (LAAOD), maximum volume of LAA (LAAVmax), and minimum volume of LAA (LAAV min) of the Res group decreased, and were lower than those of the Con group. In addition, the left atrial ejection fraction (LAEF), vessel function index and dilatation index of the Res group increased significantly postoperatively, and were higher than those of the Con group. The Res group also showed significantly higher LAA area change percentage [LAAAC (%)] and LAA emptying velocity (LAAEV) than the Con group. Moreover, age, history of hypertension, LAVmax and LAAAC (%) were identified to be the independent risk factors for postoperative recurrence of AF.
conclusionPatients with increased left atrial diameter and volume, large LAAOD, and small ejection fraction are more susceptible to AF recurrence, and LAAOD is a predictor of postoperative recurrence of AF.
