[Left ventricular assist devices in emergency medicine : Case-based analysis for emergency medical services and emergency departments].
Article in Medizinische Klinik, Intensivmedizin und Notfallmedizin, 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
backgroundLeft ventricular assist devices (LVAD) are an established treatment for advanced heart failure. Due to the continuous flow, pulse palpation, noninvasive blood pressure measurement and pulse oximetry are often unreliable in acute care.
objectiveCase-based analysis of the acute care of patients with left ventricular assist devices in emergency medical services and emergency departments, exemplified by a patient supported with HeartMate 3® and derivation of practical recommendations for action. MATERIAL AND
methodsAnonymized prehospital and clinical documentation of a 67-year-old female patient was evaluated. Monitoring, clinical assessment, device and power supply checks, pump parameters, diagnostics and triage were analyzed using consensus documents, reviews, registry data and manufacturer's data.
resultsIn this study three key problem areas emerged: unreliable standard monitoring, initial misclassification as technical device failure and necessary contextual interpretation of pump parameters. Prehospital findings included dyspnea, cyanosis, impaired consciousness and inability to obtain blood pressure or oxygen saturation values. The later device readout showed stable parameters without acute pump malfunction. The underlying cause was severe Staphylococcus aureus bacteremia with renal replacement therapy-dependent renal failure.
conclusionSevere clinical deterioration in LVAD patients is not necessarily pump-related. Key elements are perfusion assessment, device and power supply checks, interpretation of pump parameters, extended diagnostics and early consultation with an LVAD center.
