Value of Multimodality Imaging in the Early Diagnosis of Intravascular and Intracardiac Leiomyomatosis.
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
backgroundIntravenous and intracardiac leiomyomatosis (IVL/ICL) are rare benign smooth-muscle tumors that can extend from pelvic veins into the right heart, often mimicking thrombus or malignancy. CASE SUMMARY: A 51-year-old woman with uterine fibroids was referred for evaluation of a right atrial mass initially suspected to be thrombus. Multimodality imaging, including echocardiography, computed tomography, magnetic resonance imaging, positron emission tomography, venography, and intravascular ultrasound, identified a highly vascular intraluminal mass extending from the right gonadal vein through the inferior vena cava into the right atrium, consistent with IVL/ICL. She underwent single-stage en bloc resection, and pathology confirmed a benign leiomyoma. DISCUSSION: This case highlights the pivotal role of multimodality imaging in early diagnosis and multidisciplinary surgical planning, preventing treatment delay and improving outcomes. TAKE-HOME MESSAGE: Multimodality imaging is essential for early and accurate diagnosis of IVL/ICL and for guiding safe, complete resection.
