Increased coronary pericoronary adipose tissue attenuation in diabetic patients compared to non-diabetic controls: A propensity score matching analysis
Pericoronary adipose tissue (PCAT) attenuation is an indicator of active inflammation of perivascular adipose tissue, which is supposed to increase in diabetic patients. We aimed to investigate the PCAT attenuation values and high-risk plaque (HRP) features in diabetic and non-diabetic subjects with different stenotic extents.Prognostic value of myocardial perfusion imaging after first-line coronary computed tomography angiography: A multi-center cohort study
Further diagnostic testing may be required after a coronary computed tomography angiography (CTA) showing suspected coronary stenosis. Whether myocardial perfusion imaging (MPI) provides further prognostic information post-CTA remains debated. We evaluated the prognosis for patients completing CTA stratified for post-CTA diagnostic work-up using real-world data.Smoking and obesity predict high-risk plaque by coronary CTA in low coronary artery calcium score (CACS)
The AHA recommends statins in patients with CACS>100 AU. However in patients with low CACS (1–99 AU), no clear statement is provided, leaving the clinician in a grey-zone. High-risk plaque (HRP) criteria by coronary CTA are novel imaging biomarkers indicating a higher a-priori cardiovascular (CV) risk, which could help for decision-making. Therefore the objective of our study was to identify which CV-risk factors predict HRP in patients with low CACS 1–99.CTA pulmonary artery enlargement in patients with severe aortic stenosis: Prognostic impact after TAVR
TAVR is highly effective at reducing mortality of patients with severe aortic stenosis. However, despite the high rates of procedural success, some patients do not achieve a functional benefit or die within a short time period after the procedure. Pulmonary hypertension is a known predictor of poor outcome in patients undergoing TAVR and correlates strongly with PA enlargement measured on CT. Our study shows that MPA enlargement, defined as area-MPA ≥7.40 cm2 on pre-procedural CTA, is an independent predictor of 1-year mortality after TAVR. This imaging marker could be relevant in improving individual risk classification in TAVR candidates.Multi-modality imaging and operative findings of a post-TAVR ventricular septal defect

Aim of this study was to assess the accuracy of ventricular septal defects (VSD) using high pitch computed tomography angiography (CTA) of the chest in children below 1 year of age, compared to the intraoperative findings and echocardiography.Submillisievert CT angiography for carotid arteries using wide array CT scanner and latest iterative reconstruction algorithm in comparison with previous generations technologies: Feasibility and diagnostic accuracy
To assess evaluability and diagnostic accuracy of a low dose CT angiography (CTA) protocol for carotid arteries using latest Iterative Reconstruction (IR) algorithm in comparison with standard 100 kVp protocol using previous generation CT and IR.Global longitudinal strain assessment by computed tomography in severe aortic stenosis patients - Feasibility using feature tracking analysis
Global longitudinal strain (GLS) detects subclinical myocardial changes in patients with aortic stenosis (AS). Although GLS is typically measured by transthoracic echocardiography (TTE), assessment by multiphasic gated computed tomography angiography (CTA) has become recently available. We sought to evaluate the feasibility of CTA-derived GLS assessment and compare its agreement with TTE using the same post-processing software in severe AS patients undergoing transcatheter aortic valve replacement (TAVR) evaluation.Porcelain heart
Rheumatic heart disease (RHD) was the leading-cause of death in individual aged 5–20 years a century ago. Developments in diagnosis and treatment, decreased the incidence of RHD and dropped its mortality-rate to less than 10% since the 1960s. Despite the existence of proven preventive strategies in early detection and management of rheumatic fever (RF), RHD remained the most common cause of cardiovascular-mortality and morbidity in patients with RF. Previous studies have showed that Jones criteria may have insufficient support to diagnose patients with RF.
