Predictive Factors and Clinical Outcomes of Stent Malapposition in Calcified Lesions After PCI: A Retrospective Observational Study Based on OCT Assessment.
Article in Reviews in cardiovascular medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 1 paper.
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: Stent malapposition (SM) remains a significant challenge in percutaneous coronary intervention (PCI), particularly in cases involving calcified coronary lesions. However, the predictors of SM and their relationship with clinical outcomes remains unclear. This study aims to identify the predictors of SM through optical coherence tomography (OCT) and assess its impact on clinical outcomes. Methods: In this single-center, retrospective observational study, we analyzed 384 patients who underwent PCI with OCT imaging for calcified coronary lesions between January 2019 and December 2023. Patients were divided into two groups based on post-PCI OCT findings: the SM group (n = 142) and non-SM group (n = 242). We compared calcium characteristics, procedural parameters, and clinical outcomes between the two groups. Results: The SM group exhibited more severe calcium characteristics, including a larger calcium arc (295.8° ± 58.4° vs 248.6° ± 62.3°, Conclusions: Specific calcium characteristics and diabetes mellitus are strong predictors of stent malapposition in calcified coronary lesions. The presence of stent malapposition is associated with worse clinical outcomes, highlighting the importance of optimal lesion preparation and stent deployment strategies in high-risk lesions.
