Incidental discovery and surgical removal of inferior vena cava filter fragment embolization to the right ventricle with pericardial perforation during coronary angiography: a case report.

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
Background: Retrievable inferior vena cava (IVC) filters, when not removed after the period of thromboembolic risk has resolved, are prone to delayed complications such as limb fracture, migration, and embolization. Fragment embolization to the heart can result in pericardial penetration or other life-threatening sequelae yet may remain entirely asymptomatic and identified only incidentally. Case summary: A 54-year-old woman with a retrievable IVC filter placed in 2009 for pulmonary embolism, during a period of high bleeding risk from active breast cancer treatment, underwent elective left heart catheterization in 2025 for a 2-month history of chest discomfort. Coronary computed tomography (CT) angiography revealed multi-vessel coronary artery disease but did not visualize the migrated filter strut. During angiography, a linear radiopaque foreign body was seen within the right ventricle. A kidney-ureters-bladder radiograph confirmed filter fracture with a missing limb. Echocardiography 2 months earlier showed preserved bi-ventricular function and no pericardial effusion. During coronary artery bypass grafting, a fractured metallic filter limb ∼1-2 cm in length penetrating the pericardium was surgically removed. The remaining filter was left Discussion: Thin metallic struts may evade CT detection due to in-plane alignment or artefact, and echocardiography may fail to identify fragments lacking haemodynamic significance. Management options include endovascular retrieval, surgical extraction, or observation. This case highlights the importance of structured IVC filter follow-up and timely retrieval to prevent silent but potentially life-threatening complications.
