Effect of right ventricular pacing on left ventricular systolic function in patients with Tetralogy of Fallot.
Article in International journal of cardiology. Heart & vasculature, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundPrevalence of pacemaker-induced cardiomyopathy (PICM) in adults with congenital heart disease is unknown. Tetralogy of Fallot (TOF) is a common diagnosis in the adult congenital heart disease population, and the purpose of this study was to determine association between frequent right ventricular (RV) pacing and temporal decrease in left ventricular ejection fraction (LVEF) from pre-implantation to 2-years post-implantation (LVEF
methodsWe studied TOF patients that received RV leads only (N = 51) and a reference group of 7 patients with atrial pacing or biventricular pacing. We defined PICM as a ≥10% decrease in LVEF resulting in LVEF <50%. Linear regression was used to assess relationship between frequent RV pacing (≤20%, 21-40%, >40%) and LVEF
resultsPICM occurred in 2 (4%) of 51 patients in RV pacing group. LVEF
conclusionPICM occurred in 4% of TOF patients receiving RV pacing, and there was no association between frequent RV pacing and temporal decline in LVEF. Further studies are required to determine the long-term impact of RV pacing in the TOF population, and explore optimal treatment strategies.
