AbstractPurpose of ReviewMyocarditis is a heterogeneous disease with variable histologic and clinical presentation. Cardiovascular magnetic resonance (CMR) imaging recently emerged as the imaging modality of choice in myocarditis. This review summarizes recent findings and future directions in this field.Recent FindingsAdvanced quantitative T1 mapping and T2 mapping methods have the technical advantage to detect diffuse myocardial injury in myocarditis, which was not adequately addressed by standard, semiquantitative CMR techniques so far. Recent studies demonstrated that the technical advantages of T1 and T2 mapping techn...

Imaging Options in Cardiac Amyloidosis: Differentiating AL from ATTR
AbstractPurpose of ReviewCardiac amyloidosis (CA) results from the myocardial deposition of abnormally folded endogenous proteins leading to significant morbidity and mortality. Accurate and timely non-invasive diagnosis of cardiac amyloidosis and the correct identification of amyloid type are critical for choosing appropriate therapy. Disease type is defined by the precursor protein and most typically involves light chain (AL) or transthyretin (ATTR). Traditionally, cardiac amyloidosis has been suspected on the basis of characteristic echocardiographic features and confirmed with endomyocardial biopsy. Recent advances in ...

Chagas ’ Disease: Update on Current Diagnosis
AbstractPurpose of ReviewChagas ’ disease has become an emerging health problem due to increased migration. In the present review, we have summarized the usefulness of non-invasive imaging tools for the diagnosis of cardiac involvement in Chagas’ disease, with emphasis on modern technologies. M-mode, bidimensional (2-D), and t hree-dimensional (3-D) echocardiographies may allow the evaluation of left ventricular (LV) regional and global contractile function, right ventricle (RV) impairment, evidence of aneurysms and thrombi, and assessment of diastolic function in any stage of the disease.Recent FindingsNew modalities ...

Controversies in the Use of Fractional Flow Reserve Form Computed Tomography (FFR CT ) vs. Coronary Angiography
AbstractPurpose of ReviewInvasive coronary angiography (ICA) is the gold standard for the anatomical assessment of coronary artery disease. In addition, it provides assessment to coronary physiology and myocardial blood flow through fractional flow reserve (FFR). Furthermore, invasive FFR provides a clear road map that helps in the management of suspected coronary artery disease patients especially if an intermediate coronary lesion is considered. Despite all these developments, this invasive technique carries its own risk. Non-invasive coronary assessment using coronary computed tomography angiography (CCTA) is now an ...

Role of Intravascular Ultrasound in the Detection of Cardiovascular Disease in Diabetes and Metabolic Syndrome in Latin America
AbstractPurpose of ReviewIntravascular ultrasound (IVUS) is an essential tool in the cardiac cath lab, providing tomographic slices series of intra-luminal and vascular wall images with high quality and spatial resolution, that complement angiographic luminal information. It has been successfully used in research for the understanding of atherosclerotic process, and it was the first clinical method that delineated diverse patterns of atherosclerosis. IVUS also contributed to the advancement in the knowledge of restenosis after percutaneous coronary interventions (PCI).Recent FindingsRoutine clinical of IVUS is hindered in ...

The Potential Role of Combined Highly Sensitive Troponin and Coronary Computed Tomography Angiography in the Evaluation of Patients with Suspected Acute Coronary Syndrome in the Emergency Department
AbstractThe evaluation and triage of patients presenting to the emergency department (ED) with suspected acute coronary syndrome (ACS) remains to be challenging despite available guidelines and clinical evidence. The current guidelines in the USA recommend clinical risk assessment based on cardiovascular risk factors followed by serial electrocardiograms and conventional cardiac troponin measurements, which are supplemented by advanced non-invasive cardiac testing in the majority of patients. This approach is safe, but leads to a lengthy work-up and high cost of care. There is clinical need for diagnostic strategies that w...

Cardiovascular PET/MRI: Initial Clinical Experience
AbstractPurpose of ReviewThe study aims to give a review of the current state of cardiovascular hybrid PET/MRI and to outline its evolution in near future.Recent FindingsProof of feasibility of cardiovascular hybrid PET/MRI has been provided for different cardiovascular pathologies using [18F]-fluorodeoxyglucose (FDG) as tracer; hybrid FDG PET/MRI allows in acute myocardial infarction the visualization of the area-at-risk of infarction, and initial studies show the prognostic value of PET/MRI concerning functional recovery in acute myocardial infarction. FDG PET/MRI enables the detection of inflammation in viral myocarditi...

Modern Assessment of Diastolic Function
AbstractPurpose of ReviewThe goal of this review is to outline the new guidelines released by the ASE/EACVI that seek to simplify the assessment of diastolic function and evaluate the use and potential application of new and emerging technologies.Recent FindingsThe latest guidelines have decreased the number of parameters needed to evaluate diastolic function to 3. The parameters necessary include peak tricuspid regurgitation (TR) velocity, average E/e ′, and indexed left atrial volume (LAVi). At least 2 out of 3 must be positive to determine diastolic dysfunction. There are certain disease states that limit the applicat...

Current and Future Applications of Coronary CT Angiography with and Without FFR in the Emergency Room
AbstractPurpose of ReviewMultiple clinical trials have established the value of Coronary CT angiography (CCTA) for the evaluation of patients presenting to the ED with chest pain and a low to intermediate risk for acute coronary syndrome (ACS). CCTA can be used to evaluate these patients rapidly, effectively, and with relatively low cost and radiation dose.Recent FindingsNew research continues to accumulate, and despite much evidence to support its use in the ED setting, at least one recently published study has presented potentially contradictory results. Additionally, newer techniques that enhance the utility of CCTA, su...
