IVUS-Guided Orbital Atherectomy and Intravascular Lithotripsy for Severely Calcified Coronary Lesions.
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
backgroundSeverely calcified coronary lesions complicate percutaneous coronary intervention (PCI) by impairing device delivery and stent expansion, often necessitating advanced plaque-modification strategies. CASE SERIES: Three patients with calcified left anterior descending artery disease underwent intravascular ultrasound (IVUS)-guided PCI with orbital atherectomy (OA), intravascular lithotripsy (IVL), and balloon dilation. In patient 1, a balloon-uncrossable lesion was treated with OA, followed by IVL when balloon dog-boning suggested residual deep calcium. In patient 2, OA-related dissection and slow flow were managed with provisional stenting, followed by IVL for persistent proximal calcium-related resistance. In patient 3, Ellis type III coronary perforation during postatherectomy balloon dilation was sealed with a covered stent, followed by IVL for proximal lesion preparation. Angiographic and IVUS assessments showed stent expansion and apposition in patients, with no adverse events during the 5-month follow-up. DISCUSSION: These cases illustrate the feasibility of an IVUS-guided escalation strategy for resistant calcified coronary lesions. TAKE-HOME MESSAGE: This case series suggests that a stepwise, IVUS-guided multimodality strategy may facilitate successful outcomes and aid optimal stent deployment in complex calcified PCI.
