Summary: This study investigated the relationship between fibrous cap thickness (FCT) and plaque rupture and/or thrombosis using optical coherence tomography (OCT). It found that plaques with FCT between 65 and 80 μm were independently associated with an increased risk of plaque rupture and/or thrombosis compared with plaques with FCT > 80 μm.

Summary: Accurate quantification and prediction of plaque cap thickness using a combination of IVUS and OCT images showed higher accuracy and demonstrated the advantage of IO data in prediction. The study found that cap thickness data and prediction accuracy derived from IO data were significantly better than those from IVUS data.

Summary: Lower quantitative flow ratio (QFR) was found to be associated with vulnerable plaque features defined by intravascular imaging, suggesting that QFR may be a useful tool for ruling out high-risk plaques.

Summary: The occurrence of atheroma plaques in the arteries can lead to diseases such as atherosclerosis, necessitating a shorter time spent in locating and reconstructing the plaque. This paper presents a 3-D reconstruction of the atheroma plaque using an image processing algorithm on intravascular ultrasound images, providing an important decision-support tool in medical procedures. The results can contribute to early detection and prediction of atheroma plaques.

Summary: The clinical evidence strongly supports the efficacy of lipid lowering therapy in patients with coronary artery disease (CAD). However, the effects of these therapies on plaque composition and stability are still unclear. Intracoronary imaging (ICI) technologies are being used as a complement to conventional angiography to characterize plaque morphology and detect high-risk plaque features. Current studies show that pharmacological treatment can slow disease progression or promote plaque regression, depending on the degree of lipid lowering achieved. The introduction of high-intensity lipid lowering therapy has resulted in greater clinical benefit, but the atheroma regression shown in imaging trials appears more modest compared to the magnitude of clinical benefit.

Summary: This study developed an automated method for detecting lipidous plaque and assessing fibrous cap thickness in IVOCT images. The method showed excellent discriminability in detecting lipid plaque and accurately measuring fibrous cap thickness. It has the potential to enable highly automated and comprehensive evaluations of TCFAs.

Summary: In this paper, a novel perceptual organisation-aware selective transformer framework is proposed for accurate and robust segmentation of vessel walls in IVUS images. The framework utilizes temporal context-based feature encoders to extract efficient motion features of vessels and incorporates a perceptual organisation-aware selective transformer module to extract accurate boundary information. The obtained results are fused in a temporal constraining and fusion module to determine the most likely correct boundaries with robustness to morphology. Extensive evaluation on non-selected IVUS sequences demonstrates that the proposed methods outperform the state-of-the-art. The work has been integrated into a user-friendly software for automatic IVUS image segmentation.

Summary: This study aimed to investigate the impact of optical coherence tomography (OCT)-detected thin-cap fibroatheroma (TCFA) on clinical outcomes of diabetes mellitus (DM) patients with fractional flow reserve (FFR)-negative lesions. The results showed that among DM patients with FFR-negative lesions, TCFA-positive patients had a five-fold higher rate of major adverse clinical events (MACE) compared to TCFA-negative patients, suggesting a potential paradigm shift for coronary artery disease risk stratification in DM patients.

Summary: Coronary angiography has been the standard for diagnosing coronary artery disease and guiding percutaneous coronary intervention (PCI). Intravascular imaging (IVI) technologies are used in conjunction with angiography to better assess plaque morphology and optimize PCI. IVI has utility in preintervention assessment, procedural guidance, and postintervention evaluation. IVI's role in reducing major adverse cardiac events in complex lesions is emerging, and further studies are underway. This paper provides an overview of available IVI technologies, reviews evidence supporting their use in PCI, and advocates for broader utilization.

Summary: This study introduces a novel algorithm to investigate the mechanical response of arterial tissue to the remodelling of collagen fibres, predicting the optimal fibre distribution at the carotid bifurcation in healthy and diseased cases. It explores the impact of different fibre configurations on plaque stability, providing critical insights into the collagen fibre patterns necessary for maintaining plaque stability in carotid arteries.

Summary: This study investigates the frequency and outcomes of triple regression in patients with acute myocardial infarction treated with high-intensity lipid-lowering therapy. The results suggest that triple regression occurs in about one-third of these patients and is associated with alirocumab treatment, higher baseline lipid content, and reduced cardiovascular events.

Summary: An innovative SAmOCP nanoprobe with versatile functions has been developed for precise diagnosis of vulnerable atherosclerosis (AS) plaques at the molecular level. The SAmOCP nanoprobes actively recognize foam cells and specifically target vulnerable AS plaques in vivo. By utilizing the enhanced localized surface plasmon resonance effects, the encapsulated liquid perfluoropentane (PFP) can transform into abundant microbubbles, enabling greatly enhanced ultrasonic imaging capacity. The SAmOCP nanoprobes exhibit a triple-modality diagnostic efficacy of ultrasound/fluorescence/photothermal imaging, offering a promising solution for the diagnosis of vulnerable AS.

AI has the potential to improve the assessment of images of vulnerable plaque in coronary arteries, but requires robust development, testing and validation.
