Leaflet modification techniques to mitigate coronary obstruction risk during transcatheter aortic valve implantation.

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
Coronary obstruction is a rare but serious complication during transcatheter aortic valve implantation (TAVI), particularly in valve-in-valve procedures, which is associated with high mortality. This review explores various leaflet modification techniques designed to mitigate this risk. Among the most studied methods is Bioprosthetic or native Aortic Scallop Intentional Laceration to prevent Iatrogenic Coronary Artery obstruction (BASILICA), which uses transcatheter electrosurgery to lacerate the aortic valve leaflet and maintain coronary perfusion. Other promising techniques include ShortCut, a mechanical leaflet splitting device, and Undermining Iatrogenic Coronary Obstruction with Radiofrequency Needle (UNICORN), which utilises radiofrequency energy to achieve leaflet laceration. These approaches differ in their procedural complexity, equipment requirements, and clinical outcomes. Each technique's efficacy in preventing coronary obstruction is discussed, alongside the potential complications and the procedural challenges encountered in both native aortic valve and valve-in-valve settings. This review also highlights the importance of careful patient selection, advanced imaging techniques, and the need for further research to optimise these strategies.
