Mashup Score: 9Prognostic Utility of Left Atrial Strain From MRI Feature Tracking in Ischemic and Nonischemic Dilated Cardiomyopathy: A Multicenter Study | AJR - 1 month(s) ago
Background: MRI-based prognostic evaluation in patients with dilated cardiomyopathy (DCM) has historically used markers of late gadolinium enhancement (LGE) and feature-tracking (FT) derived left ventricular global longitudinal strain (LV-GLS). Early data indicate that FT-derived left atrial strain (LAS) parameters, including reservoir, conduit, and booster, may also have prognostic roles in such patients. Objective: To evaluate the prognostic utility of LAS parameters, derived from MRI FT, in patients with ischemic or nonischemic DCM, including in comparison with the traditional parameters of LGE and LV-GLS. Methods: This retrospective study included 811 patients with ischemic or nonischemic DCM [median age, 60 years; 640 men, 171 women] who underwent cardiac MRI at any of five centers. FT-derived LAS and LV-GLS were measured using two- and four-chamber cine images. LGE percentage was quantified. Patients were assessed for a composite outcome of all-cause mortality or heart-failure ho

😀 Great work by our fellow Lin Lu with her new publication in @ThoracicImaging https://t.co/egyNYOw5Rm Study looked at the diagnostic performance of #WhyCMR 2D phase contrast to diagnose HFpEF. 🗒️Conclusion: Phase contrast showed low diagnostic accuracy for HFpEF.

Mashup Score: 1Assessment of Myocardial 18F-FDG Uptake at PET/CT in Asymptomatic SARS-CoV-2–vaccinated and Nonvaccinated Patients - 5 month(s) ago
Background Patients who developed myocarditis after SARS-CoV-2 vaccination show abnormalities on cardiac MRI scans. However, whether myocardial changes occur in asymptomatic individuals after vaccination is not well established. Purpose To assess myocardial fluorine 18 (18F) fluorodeoxyglucose (FDG) uptake on PET/CT images in asymptomatic patients vaccinated against SARS-CoV-2 compared with nonvaccinated patients. Materials and Methods This retrospective study included patients who underwent 18F-FDG PET/CT for indications unrelated to myocarditis during the period before (November 1, 2020, to February 16, 2021) and after (February 17, 2021, to March 31, 2022) SARS-CoV-2 vaccines were available. Myocardial and axillary 18F-FDG uptake were quantitatively assessed using maximum standardized uptake value (SUVmax). The SUVmax in all patients and in patients stratified by sex (male or female), age (60 years), and interval between vaccination and PET/CT were compared

Background Concerns about COVID-19 vaccination induced myocarditis or subclinical myocarditis persists in some populations. Cardiac magnetic resonance imaging (CMR) has been used to detect signs of COVID-19 vaccination induced myocarditis. This study aims to: (i) characterise myocardial tissue, function, size before and after COVID-19 vaccination, (ii) determine if there is imaging evidence of subclinical myocardial inflammation or injury after vaccination using CMR. Methods Subjects aged ≥ 12yrs old without prior COVID-19 or COVID-19 vaccination underwent two CMR examinations: first, ≤ 14 days before the first COVID-19 vaccination and a second time ≤ 14 days after the second COVID-19 vaccination. Biventricular indices, ejection fraction (EF), global longitudinal strain (GLS), late gadolinium enhancement (LGE), left ventricular (LV) myocardial native T1, T2, extracellular volume (ECV) quantification, lactate dehydrogenase (LDH), white cell count (WCC), C-reactive protein (CRP), NT-proB

Diagnosing heart failure with preserved ejection fraction (HFpEF) remains challenging. Intraventricular four-dimensional flow (4D flow) phase-contrast cardiovascular magnetic resonance (CMR) can assess different components of left ventricular (LV) flow including direct flow, delayed ejection, retained inflow and residual volume. This could be utilised to identify HFpEF. This study investigated if…

Stress cardiovascular magnetic resonance (CMR) imaging is a well-validated non-invasive stress test to diagnose significant coronary artery disease (CAD), with higher diagnostic accuracy than other common functional imaging modalities. One-stop assessment of myocardial ischemia, cardiac function, and myocardial viability qualitatively and quantitatively has been proven to be a cost-effective…

Cardiac magnetic resonance (CMR) derived left ventricular global longitudinal strain (LV-GLS) for evaluating dilated cardiomyopathy patients has been addressed in studies with contradictory results. We therefore performed the first systematic review evaluating evidence on the prognostic value of CMR derived LV-GLS for ischaemic (IDCM) and non-ischaemic dilated cardiomyopathy (NDCM) patients….
