Double LLAMACORN: Bilateral Leaflet Modification Technique to Prevent Coronary Obstruction.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo describe the double LLAMACORN (Leaflet Laceration with Balloon-Mediated Annihilation to prevent coronary obstruction with radiofrequency needle) procedure as a strategy for bilateral leaflet modification before valve-in-valve transcatheter aortic valve replacement (TAVR) in a patient at high risk for coronary obstruction. KEY STEPS: The right and left leaflets were traversed using electrosurgery. Sequential bileaflet dilatation was performed using coronary balloons and positioning of 2 extra-stiff Safari wires through the leaflets. Sequential bileaflet laceration was achieved with Atlas balloons. A 23-mm Navitor was deployed, with postdilatation as needed. POTENTIAL PITFALLS: Catheter entanglement may occur, particularly in small anatomies. Hemodynamic compromise may result from aortic regurgitation after simultaneous leaflet laceration. TAKE-HOME MESSAGE: Double LLAMACORN is a feasible alternative to BASILICA (bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction), streamlining bilateral leaflet modification and preserving coronary flow.
