Transradial Endomyocardial Biopsy Forceps Bailout for Aorto-Ostial Guidewire Fracture: 24-Month Safety Follow-Up.
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
backgroundCoronary guidewire fracture complicates 0.1% to 0.2% of percutaneous coronary interventions. Aorto-ostial fragments pose retrieval challenges due to acute angulation and valve proximity. CASE SUMMARY: During left anterior descending chronic total occlusion percutaneous coronary intervention in a 58-year-old man, a right coronary artery guidewire fractured at the calcified ostium with aortic protrusion. After 55 minutes of unsuccessful conventional retrieval, endomyocardial biopsy forceps were advanced through right radial access under orthogonal fluoroscopic views with surgical standby. The fragment was secured and withdrawn in <8 minutes. DISCUSSION: To our knowledge, this represents the first reported transradial biopsy forceps retrieval of an aorto-ostial guidewire fragment. A 24-month echocardiography confirmed preserved valve integrity. This highly selective bailout requires strict prerequisites: ≥1 cm protrusion, endomyocardial biopsy experience, orthogonal imaging, and immediate surgical backup. TAKE-HOME MESSAGE: When conventional techniques fail for aorto-ostial guidewire fractures with adequate aortic protrusion, transradial biopsy forceps retrieval offers a last-resort option in experienced hands with surgical standby.
