Pacing-Induced Cardiomyopathy in a Transplanted Heart Treated With Left Bundle Branch Pacing.
Article in JACC. Case reports, 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
backgroundAtrioventricular (AV) block is a potential complication of orthotropic heart transplantation (OHT). The optimal cardiac pacing method is largely unexplored in patients after OHT. CASE SUMMARY: We present a patient with AV block after OHT in whom right ventricular pacing resulted in pacing-induced cardiomyopathy (PICM). Left ventricular function was restored with left bundle branch pacing. DISCUSSION: AV block is an uncommon complication after OHT that requires ventricular pacing. Ventricular dyssynchrony induced by right ventricular pacing may be associated with increased risk for PICM in OHT recipients. Cardiac physiologic pacing should be considered as the primary pacing strategy in this population. TAKE-HOME MESSAGES: OHT recipients may be at increased risk for PICM. Left bundle branch pacing is an effective strategy for both prevention and treatment of PICM.
