Dual Left Atrial Masses Causing Inflow Obstruction: A Rare Presentation of Primary Cardiac Intimal Sarcoma.
Article in Vascular health and risk management, 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
Aim: Primary cardiac intimal sarcoma is a rare entity with a poor prognosis, often requiring distinction from other undifferentiated cardiac sarcomas. Case Presentation: A 55-year-old female presented with symptoms of heart failure. Imaging identified dual left atrial masses compromising mitral inflow and pulmonary venous return. Surgical excision was performed, and morphological analysis revealed a high-grade spindle cell sarcoma. Crucially, the diagnostic dilemma was resolved through molecular testing; immunohistochemistry showed diffuse overexpression of MDM2 and CDK4, and fluorescence in situ hybridization (FISH) confirmed the amplification of the Conclusion: This case illustrates the diagnostic utility of MDM2 and CDK4 as specific biomarkers for cardiac intimal sarcoma. It reinforces the necessity of a multidisciplinary approach involving advanced molecular pathology to ensure accurate classification and appropriate management of rare cardiac malignancies.
