Effect of Fluoroscopy-Only Versus Transesophageal Echocardiography/Intracardiac Echocardiography Guidance in Left Atrial Appendage Occlusion on Stroke Prevention: Analysis From the RECORD I Study.
Article in Journal of the American Heart Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03917563 (Registry to Evaluate Chinese Real-World Clinical Outcomes in Patients With AF Using the WATCHMAN Left Atrial Appendage Closure Technology), which is not on this map. Not yet cited in PubMed.
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.

Abstract
backgroundEvidence regarding the link between imaging modality and stroke prevention outcomes of left atrial appendage occlusion is currently lacking.
methodsThe RECORD (Registry to Evaluate Chinese Real-World Clinical Outcomes in Patients With AF Using the WATCHMAN Left Atrial Appendage Closure Technology) trial prospectively enrolled 3096 consecutive patients undergoing left atrial appendage occlusion from 39 Chinese centers between April 1, 2019, and October 31, 2020. In the current analyses, patients were stratified into the echocardiographic guidance (transesophageal echocardiography/intracardiac echocardiography) group and the fluoroscopy-only group. The primary end point was the composite end point of death, stroke, or systemic embolism at 3 years. Outcomes were estimated using the Kaplan-Meier method. Inverse probability of treatment weighting and 1:1 propensity score matching were performed to calculate hazard ratios (HRs) for each outcome at the time of interest.
resultsAmong 3096 participants, 2603 (84.1%) underwent transesophageal echocardiography/intracardiac echocardiography-guided procedures and 493 (15.9%) underwent fluoroscopy-only guided procedures. Before discharge, procedural complications occurred in 34 patients (1.4%) in the transesophageal echocardiography/intracardiac echocardiography group and 3 patients (0.6%) in the fluoroscopy-only group (inverse probability of treatment weighting-adjusted absolute difference, -0.67 [95% CI, -1.39 to 0.05],
conclusionsFluoroscopy-only guidance, without compromising long-term stroke prevention efficacy, may serve as a streamlined and potentially accessible alternative for left atrial appendage occlusion procedures performed with the first-generation WATCHMAN 2.5 device, and these findings apply to select patients and experienced centers.
