Prosthetic valve dysfunction post-bevacizumab: a transcatheter aortic valve replacement thrombosis case report.
Article in European heart journal. 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
Background: Transcatheter aortic valve replacement (TAVR) thrombosis is a known complication, but its association with vascular endothelial growth factor (VEGF) inhibitors has not been previously reported. Case summary: A 69-year-old male with previous TAVR developed new-onset prosthetic valve dysfunction after receiving bevacizumab for age-related macular degeneration. Echocardiography revealed moderate aortic stenosis with significantly elevated gradients compared to baseline. Following discontinuation of bevacizumab and initiation of systemic anticoagulation, valve function normalized at three-month follow-up. Discussion: This first reported case of TAVR thrombosis potentially linked to bevacizumab therapy demonstrates a temporal relationship between drug administration and valve dysfunction, with subsequent resolution upon drug discontinuation and anticoagulation. Clinicians should be aware of potential thrombotic complications when prescribing bevacizumab to patients with bioprosthetic valves and maintain regular echocardiographic surveillance. Prompt anticoagulation and medication adjustment may reverse valve dysfunction. Further studies are needed to determine a causal relationship between TAVR thrombosis and VEGF inhibitors.
