Novel Management for Stuck Mechanical Aortic Valve Leaflet Following Bentall With Bovine Aortic Arch.
Article in JACC. 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
backgroundMechanical heart valves offer long-term durability but carry a risk of thrombosis, even with therapeutic anticoagulation. CASE SUMMARY: We present a case of a patient with a history of Bentall procedure and bovine aortic arch who developed a thrombotic stuck mechanical aortic valve. Despite therapeutic international normalized ratio and administration of thrombolytics, the obstruction persisted. Given the patient's high surgical risk, a novel percutaneous interventional approach was used, resulting in restoration of valve function and a favorable clinical outcome. DISCUSSION: Mechanical valve thrombosis is a rare but life-threatening condition with an incidence of 0.1% to 5.7%. Although subtherapeutic international normalized ratio is a common cause, cases may occur despite adequate anticoagulation. This report highlights an innovative, catheter-based management strategy in a complex anatomical setting, emphasizing the need for alternative therapies in nonsurgical candidates. TAKE-HOME MESSAGES: Mechanical valve thrombosis can occur even with optimal anticoagulation. Novel interventional solutions may be lifesaving in select high-risk patients.
