The DELIVER Technique: Deep Engagement of Guide or ChiLd-guIde Catheter for Burr DeliVEry and Rotational Atherectomy.
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 2 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
The delivery of the rotational atherectomy burr can sometimes be hindered in distal calcified lesions complicated by proximal vessel tortuosity or other obstacles. This problem may result in procedural failure or fatal complications, including coronary perforation, burr entrapment, or driveshaft fracture. To prevent these catastrophic outcomes and ensure successful burr delivery, we introduce the DELIVER (Deep Engagement of guide catheter or 5-F chiLd-guIde catheter for burr deliVEry and subsequent Rotational atherectomy) technique. This method involves deep catheter insertion beyond proximal vessel tortuosity or other obstacles, using strategies such as the distal balloon anchoring technique. Once the catheter is positioned, the rotational atherectomy burr is advanced through it to facilitate the atherectomy of the distal target lesion. This report presents 3 cases where the DELIVER technique was applied successfully to treat distal lesions. The technique enabled smooth and atraumatic burr delivery, even through tortuous arterial segments or other challenging anatomical structures.
