Huge Right Atrium Thrombosis Mimicking 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. 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
backgroundRight atrial thrombosis is a rare but serious condition that can mimic cardiac tumors like myxoma, posing diagnostic challenges. It often presents with nonspecific symptoms, making early detection difficult and critical for preventing complications such as embolism or heart failure. CASE SUMMARY: We report a case of a large right atrial mass initially suspected as myxoma. Laboratory tests showed elevated D-dimer (1,000 ng/mL, normal: <800 ng/mL) with normal coagulation profile and negative antiphospholipid antibodies. Imaging and clinical evaluation led to the diagnosis of a huge right atrium thrombosis rather than myxoma. DISCUSSION: Distinguishing thrombus from myxoma is crucial due to differing management strategies. Elevated D-dimer and negative autoimmune markers supported thrombosis. Echocardiography played a pivotal role in diagnosis. Awareness of such presentations can prevent unnecessary surgery. TAKE-HOME MESSAGES: Right atrial thrombosis can mimic myxoma clinically and on imaging. Comprehensive evaluation including coagulation studies, autoimmune markers, and echocardiography aids accurate diagnosis, guiding appropriate treatment and improving outcomes.
