Safety of recombinant activated factor VII for bleeding use post Heart Mate III, left ventricular assist device implantation.
Article in JHLT open, 2026. 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: Perioperative bleeding is a frequent high-risk complication, especially during Left Ventricular Assist Device (LVAD) implantation, and frequently necessitates reoperation. Bleeding control required many therapeutic options, and in refractory cases, recombinant activated Factor VII Methods: This is a retrospective single-center study for patients who developed refractory perioperative bleeding during LVAD, HeartMate III, implantation, and received rFVIIa due to the failure of other therapeutic options. The study was conducted from the first of December 2022-31 July 2025. The primary endpoint was a composite of pump thrombosis, stroke and thromboembolic events. Results: Among all HeartMate III LVAD implantations during the study period, eight patients received rFVIIa. There was no single recorded case of mortality, major stroke causing disability or device pump thrombosis. One patient (12.5%) experienced a minor stroke. There were a total of three patients (37.5%) identified to have a surgical source of bleeding, and two patients (25%) required operation re-exploration due to continued bleeding. Conclusion: This is a retrospective trial of a single cardiac center experience. rFVIIa use in refractory bleeding during HeartMate III LVAD implantation is safe with no significant additional risk of pump thrombosis or major stroke. A further large-scale investigation is needed to determine its safety and effectiveness.
