Percutaneous Aspiration of a Large Pulmonary Valve Vegetation in a Nonsurgical Candidate: A Novel Approach.
Article in JACC. Case reports, 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
backgroundPulmonary valve endocarditis is rare, and large vegetations usually require surgery; however, operative risk may be prohibitive in frail patients. CASE SUMMARY: A 77-year-old man with chronic obstructive pulmonary disease and diabetes presented with persistent fever and Streptococcus gallolyticus bacteremia. Echocardiography demonstrated a >30-mm mobile pulmonary valve vegetation. Surgery was declined because of high operative risk. Under transesophageal echocardiographic guidance, percutaneous mechanical aspiration using the Inari FlowTriever system was performed. The Inari Triever20 Curve catheter enabled directional engagement and near-complete en bloc removal with immediate echocardiographic clearance. The postprocedural course was complicated by transient systemic inflammatory response syndrome requiring short-term vasopressor support, with full recovery on continued antibiotic therapy. Follow-up confirmed sustained infection clearance without recurrence. DISCUSSION: This case demonstrates the feasibility of adapting mechanical thrombectomy systems for percutaneous debulking of pulmonary valve endocarditis when surgery is not an option. TAKE-HOME MESSAGE: Percutaneous aspiration of valvular vegetations using the FlowTriever system may represent a lifesaving alternative for selected inoperable patients.
