Cardiac Papillary Fibroelastoma as a Cause of Sudden Cardiac Arrest.
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
backgroundPapillary fibroelastomas (PFEs) are the most common primary tumors of the valvular surfaces of the heart. Although histopathologically benign, PFEs rarely result in catastrophic symptoms owing to their location and embolic potential. Echocardiography plays a crucial role in establishing the diagnosis of these tumors. CASE SUMMARY: A 61-year-old woman presented with witnessed cardiac arrest. After successful resuscitation, transesophageal echocardiogram showed a highly mobile mass attached to the aortic valve blocking the ostium of the left main coronary artery. After surgical removal, histopathologic evaluation revealed that the mass was a PFE. The patient was discharged in a stable condition. DISCUSSION: This is a rare case of a PFE resulting in prolonged ventricular arrhythmia, myocardial infarction, and cardiac arrest, emphasizing the need for early detection by echocardiography. TAKE-HOME MESSAGES: PFEs are benign, slow-growing tumors that may rarely manifest with life-threatening symptoms. Early detection with echocardiography followed by appropriate surgical resection can result in excellent outcomes.
