Introducing the use of AngioVac in nonbacterial thrombotic endocarditis: a systematic review.
Synthesis in Future cardiology, 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
introductionNonbacterial thrombotic endocarditis (NBTE) involves vegetations on heart valves without active bloodstream infection. The AngioVac device, a vacuum-based aspiration system commonly used for infective endocarditis, has potential in managing NBTE, particularly in patients unsuitable for surgery. This study systematically reviews the literature to evaluate AngioVac's effectiveness in reducing vegetations in NBTE.
methodsA systematic literature review was conducted using PubMed, Embase, Cochrane, and Web of Science databases through February 2024. Primary outcome was procedural success, defined as a ≥ 50% reduction in vegetation size on transesophageal echocardiogram. Secondary outcomes included in-hospital mortality, hospital stay length, and procedural complications.
resultsOut of 38 identified articles, 4 case reports met inclusion criteria. Patients were male with a median age of 60 years, and NBTE was associated with conditions such as lung adenocarcinoma, end-stage renal disease, and antiphospholipid syndrome. The mitral valve was the most commonly affected site. AngioVac achieved 100% procedural success, with no complications or in-hospital mortality. The average hospital stay was 2 days. Follow-up revealed one patient alive at 2 months, one deceased at 3 months and no data for two patients.
conclusionAngioVac is a promising tool for safely reducing vegetations in NBTE, especially for high-risk surgical candidates.The study design and protocol are registered with PROSPERO International Prospective Register of Systematic Reviews (registration number CRD42024505295).
