Prevention of Bilateral Coronary Obstruction During Valve-In-Valve TAVR With a Self-Expanding Valve: The BABICORN Procedure.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectiveWe present a case of valve-in-valve transcatheter aortic valve replacement in an 85-year-old woman with severe bioprosthetic aortic valve stenosis at a high risk of left and right coronary artery obstruction. This risk was mitigated by a procedure combining both BASILICA and UNICORN (BABICORN [Bileaflet Alteration with BASILICA and Iatrogenic Cusp Obliteration Using Radiofrequency Needle]) for double leaflet modification. KEY STEPS: Electrosurgical traversal of the right leaflet and creating the electrosurgical loop using 2 guide catheters and an Astato wire within. Electrosurgical traversal of the left leaflet and ballooning the leaflet fenestration. Creating the flying V and lacerating the right leaflet. Serial ballooning and ultimately lacerating the left leaflet. Deployment of the Evolut valve. POTENTIAL PITFALLS: Catheter entanglement, inadequate leaflet laceration, and stroke or systemic embolization. TAKE-HOME MESSAGE: The BABICORN procedure for double leaflet modification before valve-in-valve transcatheter aortic valve replacement with a self-expanding valve is technically feasible and preserves coronary flow in both native arteries.
