Progression Of Atherosclerotic Plaque Determined By Computed Tomography Angiography: A Practical CCTA-based SCORE
Introduction: Currently, no recommendations are endorsed by the different scientific societies on the clinical use of repeated coronary computed tomography angiography (CCTA) in patients with non-obstructive coronary artery disease (CAD). The aim of this study was to develop and validate a practical and simple CCTA risk score to predict medium-term disease progression in symptomatic patients at low-to-intermediate probability of CAD.

In Patients Undergoing Tavi, Imaging Biomarkers Derived From Preoperative Ct Scan Predict Long Term Prognosis
Introduction: In patients with severe aortic stenosis (AS) and moderate to high surgical risk, transcatheter aortic valve implantation (TAVI) is the preferred treatment. Nonetheless, a subset of those who undergo TAVI do not experience clinical betterment post-procedure. Prior studies utilizing cardiac magnetic resonance (CMR) indicate that AS-induced myocardial fibrosis correlates with poor outcomes, but CMR is not practical in these patients. Thus, our objective was to establish a CT-based approach for concurrent TAVI planning and quantification of myocardial fibrosis to identify potential non-responders to TAVI. (Source...

Predictors Of Percutaneous Coronary Intervention Derived From Coronary Ct Angiography In Patients With Chronic Coronary Syndromes
Introduction: Coronary computed tomography angiography (CCTA) provides detailed information on coronary plaques that could be helpful in selecting patients amenable for percutaneous coronary intervention (PCI). We aimed to identify anatomical (e.g. lesion location and stenosis severity) and morphological plaque features predictors of PCI and create a multiparametric score to further increase the predictive yield. Moreover, we assessed the incremental predictive value of FFRCT (Fractional Flow Reserve derived from CCTA) trans-lesion gradient ( ΔFFRCT) when integrated in the score.

Mediation Analysis Of Troponin Release And Low-attenuation Plaque Burden In Patients With Stable Chest Pain
Introduction: Coronary low-attenuation plaque (LAP) burden is a robust predictor of myocardial infarction in patients with stable chest pain. Our objective was to evaluate the association between LAP burden and systemic levels of high-sensitivity cardiac troponin T (hs-cTnT). Additionally, we sought to explore the potential underlying etiology in patients who are undergoing clinically indicated coronary CT angiography (CCTA).

Spontaneous Coronary Artery Dissection, Diagnosis And Management Without The Risks Of Invasive Angiography
Introduction: Cardiac Computed Tomographic Angiography (CCTA) has historically lacked the temporal and spatial resolution to diagnose and follow spontaneous coronary artery dissection (SCAD). An uncommon etiology of acute coronary syndrome, invasive angiographic findings of SCAD are subtle and difficult to identify regardless of operator experience. If mistaken for common coronary artery disease (CAD), serious complications can occur. CCTA may now have a role in diagnosis and management of SCAD.

Advancing Spontaneous Coronary Artery Dissection Diagnosis: Insights From Novel CCTA Approaches And Peri-Coronary Inflammation
Introduction: Spontaneous coronary artery dissection (SCAD) poses diagnostic challenges due to its varied presentation and potential iatrogenic dissection risks during invasive procedures. Standard coronary computed tomography angiography (CCTA) has limited accuracy in SCAD diagnosis, with a high false negative diagnosis rate. We explored the utility of novel CCTA approaches and peri-coronary inflammation assessment using the perivascular fat attenuation index (FAI-score) to enhance SCAD diagnosis.

Impact Of Coronary Computed Tomographic Angiography On Resource Utilization In A Rural Emergency Room
Introduction: Ramifications from the COVID-19 pandemic continue to impact health systems across the world with increased burnout among healthcare workers resulting in global staff and bed shortages. Optimal hospital resource utilization remains critical. Coronary computed tomography angiography (CCTA) can rapidly risk stratify patients with chest pain. We sought to analyze the impacts which CCTA might have on resource utilization compared to usual care with nuclear myocardial perfusion imaging (NMPI).

Challenges In Diagnosing Acute SCAD: Evaluating Conventional CCTA Analysis Amongst Multiple Readers
Introduction: Standard coronary computed tomography angiography (CCTA) is commonly used to diagnose acute spontaneous coronary artery dissection (SCAD). However, its accuracy in this context remains uncertain, and inter-reader variability poses a challenge. We aimed to assess the diagnostic performance of five independent readers in differentiating acute SCAD from normal cases using CCTA. (Source: Journal of Cardiovascular Computed Tomography)

Inferential Evaluation Of A Computer Vision Deep Learning Algorithm For Left Atrial Segmentation: Monai Vista
Introduction: Open-source computer vision radiologic applications are being developed on a harmonized platform-Medical Open Network for AI (MONAI); however, inferential clinical utility with these applications remains nascent. We compared the performance of left atrial volume calculation using two different models; MONAI Versatile Imaging SegmenTation and Annotation (VISTA) Model 2.51 and the clinical algorithm used by our institution-Visage version 5.7.0.25.

AI Evaluation Of Stenosis On Coronary CTA: Real World Comparison With Quantitative Coronary Angiography
Introduction: Machine learning has shown promising results in quantification of CAD on Coronary CT angiography (CCTA). However, its diagnostic performance in real world data has not been adequately validated. AI-based CCTA (AI-QCT) detection and grading was performed using FDA-approved analysis, and its accuracy was compared to invasive quantitative coronary angiography (QCA).

The Comparability Between CTCA And ICA In Detecting LAD Patency To Predict GraftIbility In CABG Patient Candidates
Introduction: Assessment of patency and diameter of the LAD is a useful tool to predict graftibilty for revascularization in patients with chronic total LAD occlusion where distal segment is not/poorly visualized by interventional coronary angiography (ICA). We aimed at assessing the role of coronary CT angiography (CCTA) in visualization of distal LAD for its patency and diameter prior to CABG (Source: Journal of Cardiovascular Computed Tomography)
