Novel Use of Dual-Lumen Microcatheter for False Lumen Hematoma Decompression: Tools for Consideration.
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
backgroundManagement of iatrogenic coronary dissection is essential for all interventional cardiologists considering its incidence and high associated mortality. CASE SUMMARY: A 66-year-old woman undergoing elective left and right heart catheterization for investigation of shortness of breath experienced iatrogenic catheter-induced ostial right coronary artery dissection. Use of intravascular ultrasound and repurposing a dual-lumen microcatheter enabled successful wiring of true lumen and percutaneous management. DISCUSSION: Novel use and repurposing of available coronary equipment in the form of a dual-lumen microcatheter provided additional tools for management of this dangerous complication. TAKE-HOME MESSAGES: Coronary dissection regardless of mechanism can be fatal and difficult to manage given size differences of the true and false lumen. Use of a dual-lumen microcatheter placed into the false dissection lumen with negative pressure applied can decompress the hematoma and enable wiring of the true lumen for percutaneous management.
