Cardiac magnetic resonance T1 mapping. Part 2: Diagnostic potential and applications.

Eur J Radiol 2018 Dec 21;109:235-247. Epub 2018 Oct 21.

Division of General Radiology, Department of Radiology, Medical University of Graz, Auenbruggerplatz 19/P, 8036 Graz, Austria; Research & Development, Siemens Healthcare Diagnostics GmbH, Strassgangerstrasse 315, 8054 Graz, Austria. Electronic address:

Non-invasive identification and differentiation of myocardial diseases represents the primary objectives of cardiac magnetic resonance (CMR) longitudinal relaxation time (T1) and extracellular volume (ECV) mapping. Given the fact that myocardial T1 and ECV values overlap throughout and within left ventricular phenotypes, a central issue to be addressed is whether and to what extent myocardial T1 and ECV mapping provides additional or superior diagnostic information to standard CMR imaging, and whether native T1 mapping could be employed as a non-contrast alternative to late gadolinium enhancement (LE) imaging. The present review aims to summarize physiological and pathophysiological alterations in native T1 and ECV values and summarized myocardial T1 and ECV alterations associated with cardiac diseases to support the translation of research findings into routine CMR imaging.

Determination of Agonistically Acting Autoantibodies to the Adrenergic Beta-1 Receptor by Cellular Bioassay.

Methods Mol Biol 2019 ;1901:95-102

Berlin Cures GmbH, Berlin, Germany.

Agonistically acting autoantibodies directed against the adrenergic beta-1 receptor (beta1-AABs) are a pathogenic factor in diseases of the heart and circulatory system such as dilated cardiomyopathy. Here we describe the detection of such functionally active beta1-AABs from serum samples using spontaneously beating neonatal rat cardiomyocytes, which express the fully functional adrenergic beta-1 receptor coupled with the signal transduction pathway that induces chronotropy. With serum samples added (containing beta1-AABs), an increased positive chronotropic effect is caused that can be blocked by the subsequent addition of specific beta-blockers (abolishing this chronotropic response).

Burn-associated delayed dilated cardiomyopathy evaluated by cardiac PET and SPECT: Report of a case.

J Cardiol Cases 2014 Nov 10;10(5):180-183. Epub 2014 Aug 10.

Department of Cardiovascular Medicine, Tohoku University Graduate School of Medicine, Sendai, Japan.

Dilated cardiomyopathy is a delayed-onset and rarely reported cardiac complication of burn injury although the mechanism remains unclear. We thus report a case of dilated cardiomyopathy following severe burn injury, in which technetium 99m sestamibi single-photon emission computed tomography (SPECT), iodine-123 beta-methyl-iodophenylpentadecanoic acid SPECT and F-fluorodeoxyglucose positron emission tomography (PET) were performed to evaluate the pathophysiologic condition in combination with cardiac catheterization and myocardial biopsy. The cardiac PET and SPECT images showed reduced myocardial blood flow, decreased fatty acid metabolism, and increased glucose utilization in the left ventricular lateral wall in spite of normal coronary angiography, no significant cardiac fibrosis, and inflammatory cell infiltration, which suggests that myocardial ischemia due to microcirculatory disturbance in hypermetabolic state associated with burn injury might be a causative mechanism of dilated cardiomyopathy in this case.

Toward a solution for cardiac failure in the newborn.

Xenotransplantation 2018 Dec 11:e12479. Epub 2018 Dec 11.

Department of Surgery and Department of Microbiology & Immunology, University of Michigan, Ann Arbor, Michigan.

The newborn infant with severe cardiac failure owed to congenital structural heart disease or cardiomyopathy poses a daunting therapeutic challenge. The ideal solution for both might be cardiac transplantation if availability of hearts was not limiting and if tolerance could be induced, obviating toxicity of immunosuppressive therapy. If one could safely and effectively exploit neonatal tolerance for successful xenotransplantation of the heart, the challenge of severe cardiac failure in the newborn infant might be met. Read More

Combined treatment with systemic resveratrol and resveratrol preconditioned mesenchymal stem cells, maximizes antifibrotic action in diabetic cardiomyopathy.

J Cell Physiol 2018 Dec 7. Epub 2018 Dec 7.

Department of Physiology, Faculty of Medicine, Cairo University, Giza, Egypt.

Wnt/β-catenin signaling pathway plays a crucial role in diabetic cardiomyopathy (DCM), thus we aimed at investigating the effect of one therapeutic approach with resveratrol (RSV) given systemically and combined treatment of RSV with mesenchymal stem cells (MSCs) that was either RSV-preconditioned or not on Wnt/β-catenin signaling pathway in streptozotocin-induced DCM, and to evaluate effects of RSV preconditioning on MSCs therapeutic potential. The rats were divided into control (C, n = 8), diabetic (DM, n = 8), diabetic treated with systemic RSV (DM-RSV, n = 8), diabetic treated with RSV and nonconditioned MSCs (DM-RSV-MSCs, n = 8), diabetic treated with RSV and RSV-incubated with MSCs (DM-RSV-MSCc, n = 8) and diabetic treated with RSV-conditioned MSCs (DM-MSCc, n = 8). Echocardiography (Echo) showed significant improvement of cardiac functions in all groups treated with RSV either systemic or added in culture media. Read More

Medication dosing for heart failure with reduced ejection fraction - opportunities and challenges.

Eur J Heart Fail 2018 Dec 10. Epub 2018 Dec 10.

Department of Medicine, University of Mississippi Medical Center, Jackson, MS, USA.

Multiple drug classes have shown incremental benefits in heart failure with reduced ejection fraction. Most of these trials were designed to achieve specific doses of the investigational agent. Clinical practice guidelines recommend using the same target dosing of therapies, as tolerated. Read More

Implantable cardiac defibrillators for people with non-ischaemic cardiomyopathy.

Cochrane Database Syst Rev 2018 Dec 8;12:CD012738. Epub 2018 Dec 8.

Faculty of Medicine, American University of Beirut Medical Center, Beirut, Lebanon.

Background: There is evidence that implantable cardioverter-defibrillator (ICD) for primary prevention in people with an ischaemic cardiomyopathy improves survival rate. The evidence supporting this intervention in people with non-ischaemic cardiomyopathy is not as definitive, with the recently published DANISH trial finding no improvement in survival rate. A systematic review of all eligible studies was needed to evaluate the benefits and harms of using ICDs for primary prevention in people with non-ischaemic cardiomyopathy. Read More

Heart transplantation in two adolescents with Danon disease.

Pediatr Transplant 2018 Dec 7:e13335. Epub 2018 Dec 7.

Department of Pediatrics (Cardiology), Stanford University Medical Center, Stanford University, Stanford, California.

Danon disease (DD) is an X-linked dominant disorder caused by a mutation in the lysosomal-associated membrane protein-2 (LAMP-2) gene coding for the LAMP-2 protein. We report two cases of successful heart transplantation (HT) in adolescent brothers with DD, including one who was bridged to HT for 34 days with a HeartWare left ventricular assist device. In both patients, the post-transplant course was complicated by profound skeletal muscle weakness that resolved with corticosteroid withdrawal. Read More
