Pericardial Hemangioma: A Case Report and Updated Literature Review.
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
backgroundPericardial hemangiomas are rare benign tumors that may present with variable symptoms and mimic other cardiac masses. Awareness of this entity and an organized diagnostic approach are critical. CASE SUMMARY: A 57-year-old man presented with positional chest pain. Coronary computed tomography angiography demonstrated a hypervascular pericardial mass. Cardiac magnetic resonance characterized the lesion as an epicardial tumor contiguous with the visceral pericardium, with suspicion for an intrapericardial paraganglioma. However, DOTATATE positron emission tomography/computed tomography and plasma catecholamines were normal. The patient underwent surgical excision, and histopathology analysis confirmed pericardial hemangioma. He was without recurrence at the 3-month follow-up. DISCUSSION: This case illustrates the diagnostic discordance between computed tomography and cardiac magnetic resonance in evaluating hypervascular pericardial masses and underscores the need for multimodal imaging, functional testing, and histopathological confirmation. TAKE-HOME MESSAGES: Pericardial masses with persisting diagnostic ambiguity after noninvasive imaging should prompt surgical resection for definitive diagnosis and treatment. Early surgical resection yields excellent outcomes, with cardiologists playing an essential role in recognizing the condition, guiding diagnostic work-up, and managing perioperative care.
