BACKGROUND: Cardiovascular disease (CVD) has been documented in >50% of systemic lupus erythematosus (SLE) patients, due to a complex interplay between traditional risk factors and SLE-related factors. Various processes, such as coronary artery disease, myocarditis, dilated cardiomyopathy, vasculitis, valvular heart disease, pulmonary hypertension and heart failure, account for CVD complications in SLE. METHODS: Electrocardiogram (ECG), echocardiography (echo), nuclear techniques, cardiac computed tomography (CT), cardiovascular magnetic resonance (CMR) and cardiac catheterization (CCa) can detect CVD in SLE at an early stage...

BACKGROUND/OBJECTIVES: Assessing atrial sizes by routine non-gated CT-angiography (CTA) could be of value in discriminating between pulmonary hypertension (PH) due to heart failure with preserved ejection fraction (HFpEF) and idiopathic pulmonary arterial hypertension (IPAH). We aimed to determine how left (LA) and right atrial (RA) sizes on non-gated CTA can help discriminate between these patients. METHODS AND RESULTS: In an initial study, CMR was used in 15 IPAH and 15 PH-HFpEF patients to determine LA- and RA size throughout the cardiac cycle...

OBJECTIVES: This study sought to evaluate whether patterns of myocardial change in doxorubicin-induced dilated cardiomyopathy determined using dual-energy computed tomography (CT) were similar to characterization by extracellular volume fraction (ECV) using cardiac magnetic resonance (CMR) T1-mapping and collagen volume fraction (CVF) measured using histology. BACKGROUND: Anthracycline chemoagents are effective against a wide range of malignant conditions. However, cardiotoxicity is a well-known adverse effect of these drugs...

PURPOSE: Cardiac MR (CMR) is the gold standard for left ventricular (LV) quantification. However, two-dimensional echocardiography (2DE) is the most common approach, and both three-dimensional echocardiography (3DE) and multidetector CT (MDCT) are increasingly available. The clinical significance and interchangeability of these modalities remains under-investigated. Therefore, we undertook a systemic review to evaluate the accuracy and absolute bias in LV quantification of all the commonly available non-invasive imaging modalities (2DE, CE-2DE, 3DE, MDCT) compared to cardiac MR (CMR)...

UNLABELLED: Dynamic cardiac PET is used to quantify molecular processes in vivo. However, measurements of left ventricular (LV) mass and volume require electrocardiogram-gated PET data. The aim of this study was to explore the feasibility of measuring LV geometry using nongated dynamic cardiac PET. METHODS: Thirty-five patients with aortic-valve stenosis and 10 healthy controls underwent a 27-min (11)C-acetate PET/CT scan and cardiac MRI (CMR). The controls were scanned twice to assess repeatability...

Childhood pulmonary hypertension (PH) is a heterogenous disease associated with considerable morbidity and mortality. Invasive assessment of haemodynamics is crucial for accurate diagnosis and guidance of medical therapy. However, adequate imaging is increasingly important in children with PH to evaluate the right heart and the pulmonary vasculature. Cardiac MR (CMR) and computed tomography (CT) represent important non-invasive imaging modalities that may enable comprehensive assessment of right ventricular (RV) function and pulmonary haemodynamics...

Radiological differentiation of an unknown cardiac masse is often a challenging issue. 18F-FDG-PET/CT imaging was performed to evaluate a left ventricle mass visualized on transthoracic echocardiogram (TTE) and cardiac magnetic resonance (CMR) in a patient with an history of ischemic heart disease. The metabolically inert area on the PET/CT, corresponding to the relatively homogenous hypodensity in the LV, was thought to represent an old organized LV thrombus. Histopathological examination confirmed the imaging diagnosis...

Atrial fibrillation (AF) is the commonest cardiac rhythm disorder. Evaluation of patients with AF requires an electrocardiogram, but imaging techniques should be considered for defining management and driving treatment. The present document is an expert consensus from the European Association of Cardiovascular Imaging (EACVI) and the European Heart Rhythm Association. The clinical value of echocardiography, cardiac magnetic resonance (CMR), computed tomography (CT), and nuclear imaging in AF patients are challenged...

OBJECTIVES: To evaluate the feasibility of myocardial blood flow (MBF) by computed tomography from dynamic CT perfusion (CTP) for detecting myocardial ischemia and infarction assessed by cardiac magnetic resonance (CMR) or single-photon emission computed tomography (SPECT). METHODS: Fifty-three patients who underwent stress dynamic CTP and either SPECT (n = 25) or CMR (n = 28) were retrospectively selected. Normal and abnormal perfused myocardium (ischemia/infarction) were assessed by SPECT/CMR using 16-segment model...

AIMS: Guidelines recommend evaluation of family members of sudden cardiac death victims. However, initiation of cascade screening in families with uncertain diagnoses is not cost-effective and may cause unnecessary concern. For these reasons, we set out to assess to what extent cardiac magnetic resonance imaging (CMR) would increase the diagnostic precision and thereby possibly change the indication for family screening in patients with ventricular tachyarrhythmias. METHODS AND RESULTS: We retrospectively collected data from 79 patients hospitalized with aborted cardiac arrest (resuscitated from a cardiac arrest), ventricular tachycardia (VT), or syncope who underwent a CMR at the Copenhagen University Hospital, Rigshospitalet, Denmark...

Cardiovascular magnetic resonance (CMR) imaging is often considered the reference method to assess cardiac tumors. However, little data exists concerning the effectiveness of CMR for the accurate diagnosis of cardiac masses. We sought to understand the diagnostic value of CMR for evaluation of suspected cardiac mass. A total of 249 consecutive CMR cases performed at a single center from January 2005 to June 2013 for evaluation of masses found on echocardiography or computed tomography (CT) were included. All the clinical data and imaging features of these patients were retrospectively reviewed and medical records were verified for follow up care...

Transcatheter aortic valve replacement (TAVR) has become an alternative to surgical intervention for symptomatic or severe aortic valve stenosis in patients with high surgical risk. Successful TAVR requires a multimodality imaging approach for appropriate patient selection and prosthesis sizing. Here, we describe individual imaging modalities and report their respective roles in this emerging field. To date, echocardiography remains the traditional test for determining patient candidacy and prosthesis selection, but computed tomography (CT) has been taking on an increasingly important role in the evaluation of both the aortic root anatomy and aortoiliofemoral vessels as a single examination...

A best evidence topic was written according to a structured protocol. The question addressed was: is cardiac magnetic resonance (CMR) imaging as accurate as echocardiography in the assessment of aortic valve stenosis? Altogether 239 papers were found using the reported search. Only 12 demonstrated the best evidence to answer the clinical question. Nine of these 12 papers found CMR to correlate well with transthoracic echocardiography (TTE) or transoesophageal echocardiography (TOE) in the evaluation of aortic valve stenosis...

OBJECTIVES: The antiphospholipid syndrome (APS) is an autoimmune disorder of acquired hypercoagulability characterized by vascular thrombosis, increased pregnancy morbidity, and elevated levels of antiphospholipid antibodies. Cardiac involvement in APS may be presented as heart valve disease affecting approximately a third of patients or less frequently as intracardial thombosis, pulmonary hypertension, right or left ventricular dysfunction, micro-vascular thrombosis, coronary artery, or micro-vascular disease with overt or silent clinical presentation...

A 26-year-old man with a history of bilateral lung transplantation for pulmonary cystic fibrosis 6 months before was admitted in our institution for acute heart failure. Cardiac magnetic resonance imaging (CMR) showed an increased aortic output, as aortic flow assessed by velocity mapping was twofold the pulmonary flow, an occluded superior vena cava (SVC), and enlarged azygos vein. A systemic-to-pulmonary vein fistula (SAPVF) was suspected. The selective angiography showed numerous fistulae between intercostals, thyro-cervical, internal mammary arteries and pulmonary veins...

Ventricular volumes and ejection fraction are often used in clinical decision making in patients with congenital heart disease (CHD). The referral diagnosis, radiation exposure and image quality of functional cardiac computed tomography (CT) in a relatively large cohort of patients of CHD has not been reported. This is a retrospective evaluation of functional CT studies performed in CHD patients from three institutions (1/2007-3/2013). Patient and scanner characteristics, radiation dose estimates and image quality were compared...

Imaging is fundamental to the lifelong care of adult congenital heart disease (ACHD) patients. Echocardiography remains the first line imaging for inpatient, outpatient, or perioperative care. Cross-sectional imaging with cardiovascular magnetic resonance (CMR) or computed tomography (CT) provides complementary and invaluable information on cardiac and vascular anatomy and other intra-thoracic structures. Furthermore, CMR provides quantification of cardiac function and vascular flow. Cardiac catheterization is mostly reserved for assessment of pulmonary vascular resistance, ventricular end-diastolic pressure, and percutaneous interventions...

Aortic valve disease, which includes aortic valve stenosis (AS) and/or regurgitation (AR), is the most prevalent cardiovascular disease after hypertension and coronary artery disease. Imaging modalities are essential for the staging and management of aortic valve disease. Transthoracic echocardiography (TTE) is the primary imaging modality that is used in clinical practice to assess the aortic valve morphology, the severity of aortic valve disease, and its repercussions on left ventricular (LV) function and pulmonary arterial circulation...

The assessment of the volumes, function, and mechanics of the right ventricle (RV) is very challenging because of the anatomical complexity of the RV. Because RV structure, function, and deformation are very important predictors of cardiovascular morbidity and mortality in patients with heart failure, pulmonary hypertension, congenital heart disease, or arrhythmogenic RV cardiomyopathy, it is of great importance to use an appropriate imaging modality that will provide all necessary information. In everyday clinical practice, 2-dimensional echocardiography (2DE) represents a method of first choice in RV evaluation...
