The role of molecular imaging in the assessment of cardiac amyloidosis: state-of-the-art.

Curr Radiopharm 2020 Jun 10. Epub 2020 Jun 10.

Department of Nuclear Medicine, Kantonsspital Baden, Baden. Switzerland.

Background: Cardiac amyloidosis is a progressive infiltrative disease for which new treatments are now available. As therapy should be started as early as possible to avoid complications such restrictive cardiomyopathy, arrhythmias and heart failure, a prompt and reliable diagnosis by means of non-invasive tests would be highly warranted. Electrocardiography, echocardiography and cardiac magnetic resonance imaging are all used in the evaluation of cardiac amyloidosis with varying diagnostic and prognostic accuracy, but none of these modalities can effectively differentiate the cardiac amyloid subtypes.

Cardiac Amyloidosis: Evolving Diagnosis and Management: A Scientific Statement From the American Heart Association.

Circulation 2020 Jul 1;142(1):e7-e22. Epub 2020 Jun 1.

Transthyretin amyloid cardiomyopathy (ATTR-CM) results in a restrictive cardiomyopathy caused by extracellular deposition of transthyretin, normally involved in the transportation of the hormone thyroxine and retinol-binding protein, in the myocardium. Enthusiasm about ATTR-CM has grown as a result of 3 simultaneous areas of advancement: Imaging techniques allow accurate noninvasive diagnosis of ATTR-CM without the need for confirmatory endomyocardial biopsies; observational studies indicate that the diagnosis of ATTR-CM may be underrecognized in a significant proportion of patients with heart failure; and on the basis of elucidation of the mechanisms of amyloid formation, therapies are now approved for treatment of ATTR-CM. Because therapy for ATTR-CM may be most effective when administered before significant cardiac dysfunction, early identification of affected individuals with readily available noninvasive tests is essential.

Accessory left ventricular chamber in a cat: multimodality imaging description by cardiac magnetic resonance imaging and echocardiography.

J Vet Cardiol 2020 Apr 3;28:55-61. Epub 2020 Apr 3.

Division of Clinical Veterinary Sciences, The Royal (Dick) School of Veterinary Studies, University of Edinburgh, Edinburgh, UK.

A left ventricular accessory chamber is a complex and uncommon phenotype consisting in a subdivision of the left ventricle by a thick-walled muscle bundle or septum into two cavities. Multiple aetiologies such as congenital double-chambered left ventricle and acquired endomyocardial form of restrictive cardiomyopathy have been reported. The endomyocardial form of restrictive cardiomyopathy, owing to its structural heterogeneity, can present a similar phenotype to the congenital abnormality with intraventricular lesions bridging the ventricular septum and left ventricular free wall.

Advances in the Treatment of Cardiac Amyloidosis.

Curr Treat Options Oncol 2020 Apr 23;21(5):36. Epub 2020 Apr 23.

Department of Internal Medicine, Discipline of Cardiology, Faculty of Medical Science, State University of Campinas, Campinas, Brazil.

Opinion Statement: Cardiac amyloidosis is associated with a high mortality rate, a long delay between the first signs and the diagnosis but a short interval between diagnosis and death. This scenario has changed recently due to improved disease awareness among doctors and significant progress in diagnosis thanks to multimodal imaging and a multidisciplinary approach. Therefore, during the last few years, we have had access to specific therapies for those patients. Read More

Amyloidosis as a Systemic Disease in Context.

Can J Cardiol 2020 Mar 17;36(3):396-407. Epub 2020 Jan 17.

Brigham and Women's Hospital Amyloidosis Program, Division of Cardiovascular Medicine Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.

The systemic amyloidoses are a group of diseases characterized by the deposition of amyloid, a material formed from misfolding of proteins, in one or more organs. The 2 commonest forms of amyloidosis are transthyretin amyloidosis (ATTR), derived from wild-type or mutant transthyretin, and light-chain (AL) amyloidosis, derived from abnormal circulating light chains produced by plasma cell dyscrasia. Both frequently involve the heart, producing an infiltrative cardiomyopathy with restrictive pathophysiology. Read More

A case report on transient global ventricular wall thickening secondary to acute myocarditis: Focus on the unique role of cardiac MRI.

Medicine (Baltimore) 2020 Feb;99(8):e19223

Department of Radiology, The Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Hangzhou, Zhejiang Province, China.

Introduction: Transient left ventricular wall thickening is known to develop in the acute phase of myocarditis, with several reports documenting this unusual mode of myocarditis. Diagnosing myocarditis can be challenging because symptoms, clinical exam findings, electrocardiogram results, biomarkers, and echocardiogram results are often non-specific. Therefore, cardiac magnetic resonance imaging has become the primary non-invasive imaging tool in patients with suspected myocarditis. Read More

Diagnostic imaging of cardiac amyloidosis.

Nat Rev Cardiol 2020 Jul 10;17(7):413-426. Epub 2020 Feb 10.

National Amyloidosis Centre, Division of Medicine, University College London, Royal Free Hospital, London, UK.

Systemic amyloidosis encompasses a debilitating, under-diagnosed but increasingly recognized group of disorders characterized by the extracellular deposition of misfolded proteins in one or more organs. Cardiac amyloid deposition leads to an infiltrative or restrictive cardiomyopathy and is the major contributor to poor prognosis in patients with systemic amyloidosis. In total, >30 proteins can form amyloid fibrils, but the two main types of amyloid that can infiltrate the heart are monoclonal immunoglobulin light-chain amyloid and transthyretin amyloid.

Department of Cardiovascular Medicine, Mayo Clinic, Rochester, MN, USA -

Infiltrative heart disease is an encompassing term referring to different pathological entities that involve infiltration of the myocardium by either abnormal substances or inflammatory cells. These infiltrates can impair cellular function, induce necrosis and fibrosis, or otherwise disrupt myocardial architecture resulting in a wide spectrum of structural and functional impairment. Depending on the specific disorder and stage of disease, patients may present with minimal cardiac abnormalities, or may have findings of advanced restrictive and/or dilated cardiomyopathy.

Long term CMR follow up of patients with right ventricular abnormality and clinically suspected arrhythmogenic right ventricular cardiomyopathy (ARVC).

J Cardiovasc Magn Reson 2019 12 12;21(1):76. Epub 2019 Dec 12.

Department of Cardiology, Royal Prince Alfred Hospital, Sydney, NSW, Australia.

Background: The Task Force Criteria (TFC) for arrhythmogenic right ventricular cardiomyopathy (ARVC) was updated in 2010 to improve specificity. There was concern however that the revised cardiovascular magnetic resonance (CMR) criteria was too restrictive and not sensitive enough to detect early forms of the condition. We previously described patients with clinically suspected ARVC who satisfied criteria from non-imaging TFC categories and fulfilled parameters from the original but not the revised CMR criteria; as a result, these patients were not confirmed as definite ARVC but may represent an early phenotype.

Role of Right Ventricular Strain Measured by Two-Dimensional Echocardiography in the Diagnosis of Cardiac Amyloidosis.

J Am Soc Echocardiogr 2019 07 8;32(7):845-853.e1. Epub 2019 May 8.

Department of Cardiac Imaging, University Hospital Puerta de Hierro-Majadahonda, Majadahonda, Spain. Electronic address:

Background: Cardiac amyloidosis (CA) causes restrictive cardiomyopathy usually associated with a poor prognosis. Two subtypes predominate: systemic light-chain CA (ALCA) and transthyretin-derived CA (either wild type transthyretin amyloidosis [TTRwt] or mutant transthyretin amyloidosis [TTRm]). Left ventricular (LV) apical sparing has been extensively studied using speckle-tracking echocardiography for diagnosis, but the right ventricular (RV) deformation pattern has not been described.

Endovascular treatment of stroke in children under 2 years with heart failure and ventricular assist device.

Interv Neuroradiol 2019 Oct 9;25(5):516-520. Epub 2019 May 9.

Neurorradiology Unit, University Hospital Reina Sofía, Córdoba, Spain.

Introduction: Strokes in children are characterised by a high mortality rate while, at the same time, the low number of cases makes it difficult to gain practical experience. As heart disease is the most common risk factor, and as more and more cardiological interventions are being carried out, an increase in the incidence of paediatric stroke is expected. In some cases a transplant is required. Read More

Heart failure in cardiomyopathies: a position paper from the Heart Failure Association of the European Society of Cardiology.

Eur J Heart Fail 2019 May 16;21(5):553-576. Epub 2019 Apr 16.

Berlin-Brandenburg Center for Regenerative Therapies, Deutsches Zentrum für Herz-Kreislauf-Forschung (DZHK) Berlin, Department of Cardiology, Campus Virchow Klinikum, Charite - Universitaetsmedizin Berlin, Berlin, Germany.

Cardiomyopathies are a heterogeneous group of heart muscle diseases and an important cause of heart failure (HF). Current knowledge on incidence, pathophysiology and natural history of HF in cardiomyopathies is limited, and distinct features of their therapeutic responses have not been systematically addressed. Therefore, this position paper focuses on epidemiology, pathophysiology, natural history and latest developments in treatment of HF in patients with dilated (DCM), hypertrophic (HCM) and restrictive (RCM) cardiomyopathies.

Cardiac amyloidosis: A case report and review of literature.

World J Clin Cases 2019 Mar;7(6):742-752

Department of Cardiovascular Sciences, East Carolina Heart Institute, East Carolina University, Greenville, NC 27834, United States.

Background: Cardiac amyloidosis, a disease caused by the precipitation of amyloid proteins in the myocardial extracellular matrix has been historically difficult to diagnose due to lack of specific clinical manifestations and necessity of biopsy to demonstrate amyloid deposition. However, advances in cardiovascular imaging techniques have facilitated earlier recognition of this disease. In addition, while once thought of as incurable, treatment strategies are emerging for cardiac amyloidosis, making early diagnosis essential. Read More

Light chain cardiac amyloidosis - a rare cause of heart failure in a young adult.

Rev Assoc Med Bras (1992) 2018 Sep;64(9):787-790

. Department of Cardiology, Hospital Distrital de Santarém, Santarém, Portugal.

Cardiac amyloidosis is an infiltrative cardiomyopathy, resulting from amyloid deposition within the myocardium. In primary systemic (AL-type) amyloidosis, the amyloid protein is composed of light chains resulting from plasma-cell dyscrasia, and cardiac involvement occurs in up to 50% of the patients We present a case of a 43-year-old man, with complaints of periodical swollen tongue and xerostomia, bleeding gums and haematuria for two months. His blood results showed normocytic anaemia, thrombocytopenia and a high spontaneous INR, therefore he was referred to the Internal Medicine clinic. Read More

Indications and diagnostic yield of endomyocardial biopsies for unexplained cardiomyopathy, a single center experience.

Acta Cardiol 2020 Apr 16;75(2):138-146. Epub 2019 Jan 16.

Department of Cardiology, Ziekenhuis Oost-Limburg, Genk, Belgium.

Endomyocardial biopsies (EMBs) remain the golden standard to diagnose underlying pathophysiologic process in heart failure (HF), when potential therapeutic decisions cannot be made by non-invasive techniques. However, changes in the field of non-invasive diagnostic testing might have an impact on the need for performing an EMB in certain scenarios. We performed a retrospective analysis of consecutive EMBs performed in a single, non-academic, tertiary-care centre. Read More
