Multimodal Imaging of Papillary Muscle-Origin Left Ventricular Myxoma.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundCardiac myxomas most commonly originate in the left atrium, whereas occurrences in the ventricles are rare, accounting for only 3% to 4% of cases. Their pseudoinvasive growth, which can mimic malignancy, poses significant diagnostic challenges. CASE SUMMARY: A 49-year-old asymptomatic man underwent transthoracic echocardiography, revealing a 27.5 × 16.5 mm moderately echogenic mass in the midlateral left ventricle, adjacent to the anterior papillary muscle. Further examination showed the mass with low-density margins merging with the chordae tendineae on computed tomography (54 HU), homogeneous T2 hyperintensity with delayed "cloud-like" enhancement on cardiac magnetic resonance imaging, and moderate metabolic activity (SUV DISCUSSION: This case demonstrates the value of integrated imaging techniques in differentiating pseudoinvasive cardiac myxomas from malignant tumors, thereby enhancing diagnostic approaches for ventricular masses. TAKE-HOME MESSAGES: Multimodal imaging is crucial for diagnosing cardiac tumors located in atypical regions. Recognizing benign pseudoinvasive patterns is key to avoiding unnecessary radical surgery.
