“…First, Takotsubo cardiomyopathy usually affects the apical and midventricular myocardium, but does not cause diffuse hypokinesis. Second, the patchy diffuse distribution within the subepicardium on CMR is pathognomonic for myocarditis, whereas Takotsubo cardiomyopathy is generally not associated with late gadolinium enhancement [6]. Lastly, stress-induced cardiomyopathy causes milder elevations in cardiac enzyme levels than recorded in our patient [2].…”

BackgroundFulminant type 1 diabetes is a non-autoimmune disorder characterized by sudden onset. This complication is rarely associated with myocarditis, suggesting an involvement of viral infection. We report a patient with myocarditis who was admitted for fulminant type 1 diabetes and diagnosed using a combination of non-invasive techniques.Case presentationWe describe the case of a 25-year-old Japanese man with fulminant type 1 diabetes complicated by myocarditis. The patient was admitted with flu-like symptoms and diabetic ketoacidosis, followed by chest pain the next day. Myocardial damage was suspected based on ST-segment elevation on electrocardiogram and elevation of cardiac enzymes. However, coronary angiography revealed no abnormality in the coronary arteries. We diagnosed myocarditis by a combination of echocardiography, cardiovascular magnetic resonance imaging (CMR), as well as Thallium-201 and Iodine-123 beta-methyl iodophenyl pentadecanoic acid (Tl-201 BMIPP and I-123 BMIPP) and myocardial imaging. More importantly, CMR revealed diffuse enhancement in the subepicardium of the left ventricle with late gadolinium enhancement, consistent with myocardial edema. The patient was successfully treated, received a two-week education program on diabetes and discharged without complication.ConclusionsThe rapid onset and flu-like symptoms strongly suggest the involvement of viral infection in the pathogenesis of fulminant type 1 diabetes and myocarditis. While cardiac muscle biopsy is routinely performed, this case demonstrates that a combination of non-invasive techniques, especially CMR, may successfully diagnose myocarditis in patients with fulminant type 1 diabetes.

“…The anatomy and functional images from the LV are typically imaged by acquiring rapidly either with multiple 2D-or 3Dcine images that are covering the whole heart during more than 95% of the cardiac cycle [21]. Images allow the accurate determination of end diastolic volume (EDV) and end systolic volume (ESV) which are further used to calculate ejection fraction (EF), stroke volume (SV), and cardiac output (CO) [3,12,15,16,22]. Reduced EF together with increased EDV and decreased myocardial thickness are the clearest signs of reduced systolic function and remodeling [12,13,15,23,24].…”

“…Both T 1 and T 2 mapping also allow visualization and quantification of global changes in the myocardium (Table 1) [11,44,46]. T 1 relaxation time is elevated during MI development [6,10,38,39,47] and it has been shown to distinguish between reversible and irreversible damages in post ST-elevation MI (STEMI) [22,48,49]. In chronic MI, native T 1 relaxation times are lower than in acute MI because edematous and necrotic tissues in the acute MI are replaced by smaller amounts of expanded extracellular collagen [7••, 50].…”

Purpose of Review Cardiovascular diseases are the leading cause of deaths worldwide. Many complex cellular and molecular pathways lead to myocardial remodeling after ischemic insults. Anatomy, function, and viability of the myocardium can be assessed by modern medical imaging techniques by both visualizing and quantifying damages. Novel imaging techniques aim for a precise and accurate visualization of the myocardium and for the detection of alternations at the molecular level. Recent Findings Magnetic resonance imaging assesses anatomy, function, and tissue characterization of the myocardium noninvasively with high spatial resolution, sensitivity, and specificity. Using hyperpolarized magnetic resonance imaging, molecular and metabolic conditions can be assessed non-invasively. Single photon-emission tomography and positron-emission tomography are the most sensitive techniques to detect biological processes in the myocardium. Cardiac perfusion, metabolism, and viability are the most common clinical targets. In addition, molecular-targeted imaging of biological processes involved in heart failure, such as myocardial innervation, inflammation, and extracellular matrix remodeling, is feasible. Summary Novel imaging techniques can provide a precise and accurate visualization of the myocardium and for the detection of alternations at molecular level.
