The relationship between myocardial and hepatic T1 relaxometry on cardiovascular magnetic resonance imaging and clinical outcomes late after tetralogy of Fallot repair
ABSTRACT: Background: Cardiovascular magnetic resonance imaging (CMR) can estimate diffuse myocardial fibrosis using native T1 mapping and extracellular volume fraction (ECV) quantification. Objectives: This study aimed to explore associations between, and prognostic value of, myocardial and…

Cardiovascular magnetic resonance reclassification of aortic regurgitation after transcatheter aortic valve implantation: A COMPARE-TAVI 1 substudy
ABSTRACT: Background: Aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) is a clinical concern. Echocardiography is routinely used to assess AR but relies on semiquantitative and operator-dependent measures, while cardiovascular magnetic resonance (CMR) allows direct…

Comparison of free-running whole-heart five-dimensional and four-dimensional flow imaging to standard two-dimensional flow in patients with congenital heart disease
Background: Flow quantification by cardiovascular magnetic resonance (CMR) is essential for diagnosis-making and follow-up in patients with congenital heart disease (CHD). Standard two-dimensional phase-contrast (2D flow) sequences require, however, precise image plane prescription, resulting in…

Randomized controlled trial of vericiguat in patients with coronary microvascular dysfunction causing stable chest pain (V-COM): study protocol for a randomized control trial
ABSTRACT: Background: Previous studies have shown that ∼50% of patients with stable chest pain have no obstructive coronary artery disease (CAD), yet remain at higher risk of major adverse cardiovascular events (MACE) compared to patients without chest pain. Coronary microvascular dysfunction (CMD)…

Characteristics and prognostic value of cardiovascular magnetic resonance imaging-derived left ventricular hemodynamics in pulmonary arterial hypertension
Background: There is increasing recognition of the importance of left ventricular (LV) assessment in pulmonary arterial hypertension (PAH). Hemodynamic patterns derived from hemodynamic force (HDF) analysis are an approach to evaluate hemodynamic patterns and myocardial dysfunction. However, its…

The severity of post-infarction edema suggests a bimodal pattern, whereas the extent does not
ABSTRACT: Background: Preclinical and clinical data following acute myocardial infarction (MI) have shown conflicting results whether a bimodal pattern of edematous myocardium at risk (MaR) on cardiovascular magnetic resonance (CMR) imaging during the first week exists or not. The objective was to…

Cardiac magnetic resonance imaging diastolic function assessment in preserved ejection fraction and absence of late gadolinium enhancement
ABSTRACT: Background: Cardiovascular magnetic resonance (CMR) accurately measures left ventricular (LV) ejection fraction (EF) and late gadolinium enhancement (LGE), but is not commonly used for diastolic function. This study combined unsupervised machine learning and diastolic function with cine…

Cardiovascular magnetic resonance detects subclinical cardiac involvement in giant cell arteritis
ABSTRACT: Background: To assess cardiac involvement in patients with newly diagnosed giant cell arteritis (GCA) using cardiovascular magnetic resonance (CMR). Methods: In this prospective single-center study, patients with newly diagnosed GCA underwent CMR at baseline and under therapy 6 months…

Quantitative assessment of cardiac phosphocreatine metabolism under physiological and pharmacological stress using chemical exchange saturation transfer magnetic resonance imaging
Background: Phosphocreatine (PCr) exhibits a distinct chemical exchange saturation transfer (CEST) resonance at ∼2.5 ppm with slower exchange kinetics and lower pH sensitivity than creatine. This pilot study evaluated the feasibility of quantifying myocardial PCr-dominated concentration ([PCr]d)…

In vivo atherosclerotic plaque characterization using 7T quantitative T2*mapping distinguishes symptomatic middle cerebral artery plaques
ABSTRACT: Background: Intraplaque T2* values help to identify symptomatic carotid plaques and correlate with intraplaque iron deposits in plaque progression. However, intracranial T2* mapping in vivo at 3T magnetic resonance imaging (MRI) is challenging due to limited resolution and signal-to-noise…

Clinical implications of vessel wall imaging—State-of-the-art review
Diseases of the arterial wall are best diagnosed using vessel wall magnetic resonance imaging (MRI) since luminal imaging does not show the extent of wall pathology. Intracranial and extracranial carotid artery pathology such as atherosclerosis, dissections, vasculitis, and occlusions can lead to…

A radiomics-based approach with automated segmentation for identifying symptomatic basilar artery plaques in acute stroke
ABSTRACT: Background: Intracranial atherosclerotic disease (ICAD) is a leading cause of ischemic stroke worldwide, with basilar artery atherosclerosis frequently involved. Despite therapeutic advances, patients with basilar artery atherosclerosis remain at substantial risk of recurrent stroke…

Synthetically trained convolutional neural networks for time-resolved aortic segmentation of four-dimensional flow magnetic resonance imaging
Background: Supervised learning-based approaches are increasingly used for vessel segmentation in four-dimensional (4D) flow cardiovascular magnetic resonance (CMR). However, their widespread adoption is challenged by the need for diverse, reliably annotated datasets, sensitivity to acquisition and…

Contrast-free postoperative imaging of the pulmonary arteries: Intraindividual comparison of relaxation-enhanced angiography without contrast and triggering and time-resolved contrast-enhanced magnetic resonance angiography
Background: Flow-independent, three-dimensional isotropic non-contrast magnetic resonance angiography (MRA) such as relaxation enhanced angiography without contrast and triggering (REACT) are increasingly established as alternatives to contrast-enhanced MRA (CE-MRA) for assessment of the pulmonary…

Assessing changes in aortic motion and hemodynamics after valve-sparing aortic root surgery in Marfan syndrome using four-dimensional balanced steady-state free precession and four-dimensional flow cardiovascular magnetic resonance
ABSTRACT: Background: Aortic root surgery in patients with Marfan syndrome (MFS) has significantly improved survival, allowing time for distal aortic complications such as type B aortic dissection (TBAD) to emerge. The implantation of a non-compliant synthetic graft may alter aortic biomechanics…

Aortic displacement and hemodynamics are abnormal in patients with Marfan syndrome: A combined four-dimensional balanced steady-state free precession and four-dimensional flow cardiac magnetic resonance study
Background: Marfan syndrome (MFS) patients with a history of aortic root surgery (ARS) are at increased risk of type B aortic dissection, possibly because the noncompliant graft fails to absorb systolic forces, leading to undampened flow in the proximal descending aorta (pDAo). In this study, we…

Spatiotemporal deep learning for scar screening in cardiovascular magnetic resonance: Toward selective use of gadolinium
Background: Late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) is the gold standard for assessing myocardial scar. However, a substantial proportion of patients referred for CMR scar assessment are ultimately found to have no evidence of myocardial scarring. Purpose: To…

Fontan conduit cross-sectional area and relationship to exercise performance
ABSTRACT: Background: The synthetic extracardiac (EC) Fontan conduit may become inadequate as patients grow, potentially limiting cardiovascular capacity. Objective: To evaluate the relationship between EC-Fontan conduit cross-sectional area (CSA), indexed to body surface area (BSA), and exercise…
