Percutaneous Mechanical Aspiration Revealing Lambl's Excrescences Initially Suspected as Papillary Fibroelastomas.

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
Mobile valvular echodensities such as papillary fibroelastomas (PFEs) and Lambl's excrescences can appear similar on imaging yet differ markedly in management. PFEs are typically resected to prevent embolic events, whereas Lambl's excrescences are benign and not treated surgically. We report 2 high-surgical risk patients with mobile aortic valve lesions presumed to be PFEs who underwent percutaneous mechanical aspiration. Both procedures achieved safe lesion debulking without complication, and histopathologic analysis revealed Lambl's excrescences rather than PFEs. These first-in-human cases demonstrate that percutaneous mechanical aspiration can serve both diagnostic and therapeutic purposes, providing definitive tissue characterization and potentially sparing patients unnecessary surgery.
