Predictors and Prognostic Implications of Myocardial Injury After Transcatheter Aortic Valve Replacement.
Article in Texas Heart Institute journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Myocardial injury (MI) is not unusual after transcatheter aortic valve replacement (TAVR). To determine precipitating factors and prognostic outcomes of MI after TAVR, we retrospectively investigated relationships between MI after TAVR and aortic root dimensions, baseline patient characteristics, echocardiographic findings, and procedural features. Of 474 patients who underwent transfemoral TAVR for severe aortic stenosis in our tertiary center from June 2011 through June 2018, 188 (mean age, 77.7 ± 7.7 yr; 96 women [51%]) met the study inclusion criteria. Patients were divided into postprocedural MI (PMI) (n=74) and no-PMI (n=114) groups, in accordance with high-sensitivity troponin T levels. We found that MI risk was associated with older age (odds ratio [OR]=1.054; 95% CI, 1.013-1.098; P=0.01), transcatheter heart valve type (OR=10.207; 95% CI, 2.861-36.463; P=0.001), distances from the aortic annulus to the right coronary artery ostium (OR=0.853; 95% CI, 0.731-0.995; P=0.04) and the left main coronary artery ostium (OR=0.747; 95% CI, 0.616-0.906; P=0.003), and baseline glomerular filtration rate (OR=0.985; 95% CI, 0.970-1.000; P=0.04). Moreover, the PMI group had a longer time to hospital discharge (P=0.001) and a higher permanent pacemaker implantation rate (P=0.04) than did the no-PMI group. Our findings may enable better estimation of which patients are at higher risk of MI after TAVR and thus improve the planning and course of clinical care.
