Severe restenosis after stentless treatment with coronary intravascular lithotripsy for calcified nodule lesions: a serial observation with IVUS.
Article in Oxford medical case reports, 2024. 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
An 82-year-old woman with a history of myocardial infarction presented with worsening effort angina. Coronary angiography (CAG) revealed 75% stenosis in the proximal left anterior descending artery (LAD), with intravascular ultrasound (IVUS) identifying a severe calcified nodule near a previously implanted drug-eluting stent. The lesion was treated with intravascular lithotripsy (IVL) and a drug-coated balloon (DCB), avoiding left main crossover stenting. Despite initial success, the patient experienced restenosis three months later, managed conservatively based on favorable DFR/FFR values. However, worsening symptoms led to repeat CAG, revealing 99% restenosis with calcified nodule. A second IVL was performed, followed by crossover stenting from the left main to the LAD, achieving successful stent expansion. This case underscores the potential for severe restenosis following IVL and DCB angioplasty, highlighting the limitations of IVL in reducing calcified plaque volume and the importance of close follow-up.
