Outcomes of Left Bundle Branch Area Pacing in Heart Failure Patients: A Systematic Review.
Synthesis in Annals of noninvasive electrocardiology : the official journal of the International Society for Holter and Noninvasive Electrocardiology, Inc, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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
backgroundLeft bundle branch area pacing (LBBAP) is an emerging physiological pacing technique that restores ventricular electrical synchrony by directly engaging the left conduction system. It has been proposed as an alternative to conventional pacing strategies, particularly in heart failure patients with reduced left ventricular ejection fraction (LVEF ≤ 50%).
methodsA systematic literature search of PubMed, MEDLINE, and Scopus was conducted up to December 2024 in accordance with PRISMA guidelines. Sixteen studies involving 5680 patients were included. Reported outcomes included changes in LVEF, QRS duration (QRSd), hospitalization rates, complications, and mortality. Due to heterogeneity among studies, a qualitative narrative synthesis was performed.
resultsLBBAP was associated with significant improvements in cardiac function, with most studies reporting increased LVEF and marked reductions in QRSd, indicating improved electrical synchrony. Complication rates were low, with rare events such as pneumothorax and lead dislodgement. Heart failure-related hospitalizations were lower with LBBAP compared with biventricular pacing (19.05% vs. 30.00%), while mortality rates remained low across pacing strategies. Overall, LBBAP demonstrated superior electrical resynchronization and favorable clinical outcomes compared with conventional pacing modalities.
conclusionLBBAP is a promising pacing strategy that improves electrical synchrony and cardiac function with a favorable short- to mid-term safety profile. Further large-scale randomized studies are needed to establish its long-term efficacy and safety.
