Navigating The 2022 Global Contrast Media Shortage: The Use Of Non-contrast Cardiac Computed Tomography Or Cardiac Magnetic Resonance Imaging For Pre-procedural Planning For Pulmonary Vein Isolation For Atrial Fibrillation
Introduction: Due to the recent shortage of iodinated contrast media (ICM), we implemented the use of non-contrast cardiac computed tomography (NCCT) and cardiac magnetic resonance imaging (CMR) for the pre-procedural planning of pulmonary vein isolation (PVI) to help conserve ICM supply in our hospital. We investigated the differences in procedure-related outcomes following the use of NCCT or CMR in comparison to the use of cardiac computed tomography angiography (CCTA) for pre-procedural planning for PVI.

Impact Of Coronary Ct Angiography In Asymptomatic Diabetic Patients - Pilot Study
Introduction: The previous FACTOR-64 study indicated that CCTA screening in asymptomatic patients with diabetes mellitus (DM) showed a trend towards improving outcomes but percutaneous coronary intervention (PCI) was a suggested therapy. The ISCHEMIA and COURAGE trials have shown that PCI does not improve outcomes in patients with obstructive coronary artery disease (CAD) compared to medical therapy. There is limited data on the impact of CCTA on patient management for asymptomatic type 2 DM patients in terms of medical therapy change. (Source: Journal of Cardiovascular Computed Tomography)

Optimization And Scaling Of Coronary CT Angiogram Workflows - Perspectives From A Quaternary Care Center
Introduction: Recognition of coronary CT angiogram(CCTA) as a 1st-line modality for chest pain evaluation by various guidelines has led to an increase in imaging requests. Many barriers hinder its scaling like scanner capability, workforce,& geography. CCTAs also require longer time slots for patient preparation, and physician supervision. The aim of this interrupted time-series analysis is to evaluate the impact of various iterative interventions to optimize CCTA workflow& meet increasing demands.

Stress Computed Tomography Perfusion Versus Stress Cardiac Magnetic Resonance For The Management Of Suspectedor Known Coronary Artery Disease: Resources And Outcomes Impact (Strategy II Study)
Introduction: Coronary computed tomography angiography (CCTA) is performed as non-invasive "gatekeepers" to invasive coronary angiography (ICA) but intrinsically lacks physiologic data to assess hemodynamic significance of coronary artery disease (CAD). Stress CT perfusion (Stress-CTP) is a recently evolved imaging modality able to assess inducible myocardial perfusion defects. The aim of this study is to compare resources and outcomes of combined CCTA+Stress-CTP versus stress cardiovascular magnetic resonance (Stress-CMR) in symptomatic patients with suspected or known CAD.

Quantitative Evaluation Of Excessive LV Trabeculation - A Comparison Between Cardiac CT And MRI
Introduction: Excessive trabeculation of the left ventricle (LV), or LV non-compaction, lacks a universally accepted diagnostic criterion; different imaging methods and quantitative metrics yield vastly different rates of disease prevalence. One objective of the International Consortium for Multimodality Phenotyping in Adults with Non-compaction (NONCOMPACT; ID:NCT04424030) study is to investigate the role of CT in the diagnosis of excessive trabeculation by comparing the quantification of the trabeculated layer between CT and MR in the same subjects.

Identification Of Morphologic And Inflammatory Predictors Of Instent-Restenosis Using CCTA
Introduction: Despite the introduction of drug-eluting stents and significant improvement of stent technology the occurrence of instent-restenosis (ISR) in the coronary arteries remains a major limitation with a substantial economic impact. The goal of this study was to identify CCTA-based plaque and perivascular characteristics which are predictive of ISR. (Source: Journal of Cardiovascular Computed Tomography)

Quantification And Characterization Of Coronary Atherosclerosis By An Artificial Intelligence-powered Coronary Computed Tomography Angiography Algorithm. A Direct Comparison With Intravascular Ultrasound In The Invictus Study
Introduction: Automated assessment of coronary atherosclerosis severity and phenotype by artificial intelligence (AI) applied to coronary computed tomography angiography (CCTA) can optimize image processing times, standardize image interpretation and quantification, and minimize inter-observer variability. However, studies assessing the diagnostic performance of AI-based CCTA algorithms compared to invasive intravascular imaging are lacking. (Source: Journal of Cardiovascular Computed Tomography)

Assessment Of Ventricular Function In Patients With Congenital Heart Disease And Pacemakers: An Echocardiography And Cine Computed Tomography Agreement Study
Introduction: Patients with congenital heart disease (CHD) and permanent pacemakers or implantable cardioverter defibrillators (PPM/ICD) are at risk for the development of ventricular dysfunction. Echocardiography can be challenging due to poor acoustic windows, artifact, or abnormal ventricular morphology. Cine cardiovascular computed tomography (CCT) is increasingly performed to assess ventricular function, but its agreement with other imaging modalities in this population is unknown. We sought to study the agreement between echocardiography and cine CCT in ventricular function assessment in patients with CHD and PPM/ICD...

Intracardiac Shunt Assessment Using Ct Coronary Angiography
Introduction: Detection of intracardiac shunts using CT Coronary Angiography (CTCA) is currently based on anatomical demonstration of defects. We aimed to assess a novel technique using a standard CTCA test bolus in detecting shunts independent of anatomical assessment and provide an estimate of Qp/Qs.

Significance Of Using 3D Imaging Modalities In Vascular Ring Patients
Introduction: Vascular rings are rare congenital anomalies of the aortic arch and/or its derivatives that cause compression of the tracheobronchial tree leading to respiratory and esophageal symptoms. Diagnosis can be easily made by using reconstructed three-dimensional (3D) computed tomography (CT) imaging and the pre-planning of the surgical procedure can be improved by 3D printing of the heart anatomy. Our abstract describes a vascular ring patient presented with dyspnea and misdiagnosed as having asthma. (Source: Journal of Cardiovascular Computed Tomography)
