Impact of Rapid Pacing Time on Myocardial Injury in Transcatheter Aortic Valve Implantation for Non-End-stage Renal Disease Patients.
Article in CJC open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
Background: Periprocedural myocardial injury (PMI) is a concern in transcatheter aortic valve implantation (TAVI), with rapid pacing (RP) suspected to be a contributing factor. PMI is defined by elevated troponin levels. In this study we determined the net effect of RP on PMI after excluding patients with severe renal dysfunction by evaluating troponin elevation after TAVI. Methods: We included 137 patients who underwent TAVI between September 2023 and January 2025. The association between renal function and cardiac troponin T (cTnT) level was investigated. Patients were categorized according to the RP time (RPT) to investigate its association with cTnT elevation, PMI, and short-term outcomes. The 100 patients with an estimated glomerular filtration rate (eGFR) ≥ 30 mL/min per 1.73 m Results: The eGFR inversely correlated with cTnT levels ( Conclusions: A longer RPT significantly increased troponin levels, indicating PMI, which was associated with worse short-term prognosis of cardiovascular events. However, other factors, such as renal dysfunction, rather than only longer RPT, are also associated with increased troponin level.
