Quantitative Coronary Angiography Guidance for Drug-Eluting Stent Implantation: A Narrative Review.
Article in Health science reports, 2024. 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
Background: Percutaneous coronary intervention (PCI) using drug-eluting stents is an established strategy for the treatment of significant obstructive coronary artery disease. Evidence supports that intravascular imaging-guided PCI offers advantages over conventional angiography-guided PCI, though its use is limited, likely due to high costs. Angiography-guided PCI relies on visual estimation, leading to inter- and intra-observer variability and suboptimal outcomes. Quantitative coronary angiography (QCA) provides reliable information about vascular dimensions, overcoming these limitations. Poststenting postdilation with appropriately sized noncompliant balloons improves outcomes by increasing lumen area and reducing stent malapposition. Aims: We investigated the procedural details of each modality used to guide PCI and assessed the utility of QCA-guided PCI with routine postdilation when intravascular imaging is unavailable. Methods and Results: A systematic search was conducted from inception to May 31, 2024, identifying nine randomized controlled trials (with over 500 patients) that compared outcomes of PCI guided by intravascular imaging versus conventional angiography or QCA. The findings indicate that intravascular imaging guidance significantly improves clinical outcomes compared to angiography guidance. Notably, QCA-guided PCI with routine postdilation yielded outcomes comparable to those achieved with intravascular imaging-guided PCI. Conclusions: QCA-guided PCI with routine postdilation may be a viable alternative for improving PCI outcomes, especially in settings where intravascular imaging is unavailable.
