Mitral Valve Blood Cyst Discovered as an Incidentaloma in Trauma Evaluation.
Article in JACC. Case reports, 2026. 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
backgroundCongenital blood cysts of the cardiac valves are rare incidental findings most commonly affecting the mitral valve and can be diagnostically challenging when discovered during evaluation of concurrent cardiac pathology or trauma. CASE SUMMARY: A 31-year-old woman presented as a level 1 trauma activation after sustaining multiple stab wounds to the left chest. Computed tomography identified pneumopericardium and a left ventricular hypodensity concerning for thrombus or laceration. Transthoracic echocardiography revealed a mitral valve mass. Transesophageal echocardiography further characterized it as a 2.0 × 1.5 cm cystic structure attached to the ventricular aspect of A2/A3 scallops of the mitral leaflet. Cardiac magnetic resonance confirmed a water-based cystic lesion with no perfusion or enhancement, establishing the diagnosis of a congenital blood cyst. DISCUSSION: This case illustrates the critical role of multimodal imaging in differentiating congenital blood cysts from traumatic cardiac lesions. TAKE-HOME MESSAGES: Multimodal imaging is essential to distinguish congenital blood cysts from traumatic cardiac injury, preventing unnecessary surgical intervention. Conservative management with surveillance imaging is appropriate for asymptomatic blood cysts without significant valvular dysfunction.
