BACKGROUND: Patients with transmural myocardial infarction (MI) who undergo endocardial-only substrate ablation are at an increased risk of ventricular tachycardia (VT) recurrence. Late gadolinium-enhanced cardiac magnetic resonance (LGE-CMR) could be used to assess infarct transmurality (IT). However, the degree of IT associated to epicardial arrhythmogenic substrate (AS) has not been determined. OBJECTIVE: To determine the degree of IT observed in LGE-CMR and multi-detector computed tomography (MDCT) that predicts the presence of epicardial AS...

Cardiovascular imaging with calcium scoring computed tomography (CT), coronary CT angiography (CCTA), and cardiac MRI (CMR) have advanced rapidly over recent years. These imaging modalities have increased in availability, accessibility, and clinical practicality due to technological advances allowing for significant radiation dose reduction for high-quality CCTA and for rapid and reliable imaging techniques in CMR. Hardware and software developments are continually increasing efficiency and accuracy of postprocessing...

PURPOSE: An accurate evaluation of left ventricular volumes, mass, and ejection fraction (EF) and an early exclusion or detection of significant coronary artery disease or cardiac allograft vasculopathy are mandatory for clinical management and prognosis assessment of heart-transplanted patients (HTP). The purpose of this article was to evaluate the role of dual-step prospective electrocardiography-triggered Dual-Source CT (pECGdual-step-DSCT) in HTP for the assessment of left-ventricular function, in comparison with echocardiography (echo) and cardiac magnetic resonance (CMR) performed on the same day, and of the coronary arteries as well...

AIMS: Cardiac affection constitutes a major limiting condition in systemic sarcoidosis. The primary objective of this study was to investigate the persistence rate of cardiac sarcoid involvement by cardiovascular magnetic resonance (CMR) imaging in patients diagnosed with cardiac sarcoidosis (CS). Moreover, we examined the additional insights into myocardial damage's characteristics gained by somatostatin receptor scintigraphy. METHODS AND RESULTS: In a pilot study, we had previously identified cardiac involvement-diagnosed by CMR imaging-to be present in 29 of 188 patients (15...

Inflammation, microvascular and macrovascular ischemia, valvular disease, and fibrosis are the main causes of cardiovascular disease (CVD) in autoimmune rheumatic diseases (ARDs). The silent presentation and the high mortality and/or morbidity of CVD in ARDs necessitate a reliable tool for early diagnosis. Noninvasive cardiovascular imaging, including echocardiography, nuclear imaging, cardiovascular computed tomography (CT), cardiac magnetic resonance (CMR), and hybrid imaging modalities, constitutes the main tool for monitoring of CVD in ARDs...

The purpose of this work was to develop a framework for 3D fusion of CT coronary angiography (CTCA) and whole-heart dynamic 3D cardiac magnetic resonance perfusion (3D-CMR-Perf) image data-correlating coronary artery stenoses to stress-induced myocardial perfusion deficits for the assessment of coronary artery disease (CAD). Twenty-three patients who underwent CTCA and 3D-CMR-Perf for various indications were included retrospectively. For CTCA, image quality and coronary diameter stenoses > 50% were documented...

Mitral regurgitation (MR) is frequent and associated with increased mortality and morbidity when severe. It may be caused by intrinsic valvular disease (primary MR) or ventricular deformation (secondary MR). Imaging has a critical role to document the severity, mechanism, and impact of MR on heart function as selected patients with MR may benefit from surgery whereas other will not. In patients planned for a surgical intervention, imaging is also important to select candidates for mitral valve (MV) repair over replacement and to predict surgical success...

Pericardial diseases have changed their epidemiology in the past few years. With the aging population and decreasing incidence of communicable diseases, the causes of pericardial diseases have significantly changed from infectious and malignant to postradiation and cardiac surgery causes. Despite that, pericardial diseases remain difficult to diagnose. The accurate and timely diagnosis of these diseases is essential to avoid the late sequela of pericardial constriction and pericardial cirrhosis. Echocardiography remains the first test of choice for the assessment of patients with suspected pericardial diseases...

Right ventricular (RV) structure and function is clinically important in a wide range of conditions. While conventional echocardiography (echo) methods are widely used, its limitations in RV assessment due its complex geometry are well recognized. New applications of traditional echo methods as well as emerging echo techniques including 3-dimensional (3D) echo and speckle tracking strain have the potential to overcome limitations of conventional echo, though widespread clinical use remains to be seen. Volumetric methods using cardiac magnetic resonance (CMR) and computed tomography (CT) provide accurate assessment of RV function without geometric assumptions...

BACKGROUND: Melanoma metastasizing to the heart (cardiac melanoma) is a rare entity that has been described only in autopsy studies or isolated pre-mortem case reports. We aim to better characterize cardiac melanoma, and describe its presenting features, imaging findings, and disease course with a case series collected over nearly 30years. METHODS: We performed a retrospective review of all patients diagnosed with cardiac melanoma at the Mayo Clinic from 1988 to 2015...

BACKGROUND: CT-FFR is an area of growing interest in the field of cardiac imaging. However, the specific anatomic location distal to a lesion of interest where CT-FFR should be computed to yield the most valid results has not been examined. This study investigated the most appropriate anatomic location distal to a coronary artery stenosis for obtaining CT-FFR measurements. METHODS: 73 patients (60 ± 9 years; 58% male) with at least one coronary lesion with 40-90% stenosis on coronary CTA (either a 2 × 128 slice or a 2 × 192 slice dual-source CT scanner) underwent stress cardiac magnetic resonance (CMR) perfusion imaging for inducible ischemia...

Sudden cardiac death (SCD) is a devastating event in athletes. Screening efforts that were first directed at athletes younger than 35 years, are now focusing on the rapidly growing group of older sportspersons. Athletes aged ≥35 years have a 10-fold increased risk of exercise-related cardiac arrest, mostly due to coronary artery disease (CAD). Although cardiac imaging is pivotal in identifying CAD, the role of imaging modalities in screening asymptomatic older sportspersons remains unclear. We performed a scoping review to identify the role of cardiac imaging to detect CAD in older sportspersons and to identify gaps in the existing literature...

Myocardial infarction (MI) is a major cause of death and disability worldwide. The incidence is not expected to diminish, despite better prevention, diagnosis and treatment, because of the ageing population in industrialized countries and unhealthy lifestyles in developing countries. Nowadays it is highly requested an imaging tool able to evaluate MI and viability. Technology improvements determined an expansion of clinical indications from coronary plaque evaluation to functional applications (perfusion, ischemia and viability after MI) integrating additional phases and information in the mainstream examination...

A large number of studies support the increasingly relevant prognostic value of the presence and extent of delayed enhancement (DE), a surrogate marker of fibrosis, in diverse etiologies. Gadolinium and iodinated based contrast agents share similar kinetics, thus leading to comparable myocardial characterization with cardiac magnetic resonance (CMR) and cardiac computed tomography (CT) at both first-pass perfusion and DE imaging. We review the available evidence of DE imaging for the assessment of myocardial infarction (MI) using cardiac CT (CTDE), from animal to clinical studies, and from 16-slice CT to dual-energy CT systems (DECT)...

Aims: To investigate the possibility that vorticity assessed by four-dimensional flow cardiac magnetic resonance (4D-Flow CMR) in the left ventricle of patients with mild-to-moderate chronic obstructive pulmonary disease (COPD) is a potential marker of early LV diastolic dysfunction (LVDD) and more sensitive than standard echocardiography, and whether changes in vorticity are associated with quantitative computed tomography (CT) and clinical markers of COPD, and right ventricular (RV) echocardiographic markers indicative of ventricular interdependency...
