Reassessing single-stent techniques for isolated left anterior descending ostial disease: a two-year intravascular ultrasound-guided retrospective comparison of precise ostial, floating, and crossover stenting strategies.

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
BACKGROUND/
objectivesPercutaneous coronary intervention (PCI) for isolated left anterior descending (LAD) ostial lesions remains challenging, with limited comparative data on stenting strategies. We aimed to evaluate the procedural and long-term outcomes of three single-stent techniques: precise ostial stenting (POS), floating stenting (FS), and crossover stenting (CS).
methodsIn this retrospective study, 116 patients with isolated LAD ostial disease underwent intravascular ultrasound (IVUS)-guided PCI using one of the three strategies. Baseline characteristics, procedural details, IVUS findings, and major adverse cardiac and cerebrovascular events (MACCEs) over two years were compared.
resultsCompared to POS and FS, CS resulted in larger minimal stent area at the ostium, and a higher rate of complete stent coverage (100% vs. 39.5% and 23.1%, p < 0.001). At 2-year follow-up, MACCE rates were significantly lower in the CS group (2.6%) compared to FS (13.5%) and POS (15.8%, p = 0.039), mainly due to reduced target lesion revascularization. FS showed improved coverage compared to POS, but inferior angiographic outcomes and higher event rates than CS.
conclusionsIn IVUS-guided PCI for isolated LAD ostial lesions, CS offers superior ostial coverage and clinical outcomes. FS may serve as a compromise when anatomical constraints limit crossover. These findings support a tailored strategy based on lesion characteristics and IVUS assessment.
