BACKGROUND: Myocardial uptake of bone tracers has emerged as useful tool for the early detection of transthyretin amyloidosis (ATTR). The prevalence of wild-type ATTR (ATTRwt) in individuals remains to be established. METHODS: All whole body bone scans performed in individuals ≥ 75 years with no previous clinical suspicion of ATTR were revised in a population-based university hospital over a 7-year period (1509 studies corresponding to 1114 patients; 80...

Transthyretin-related (ATTR) cardiac amyloidosis is currently lacking a disease-modifying therapy. Despite demonstration of effectiveness in halting amyloid deposition, no study focused on epigallocatechin-3-gallate (EGCG) impact on patient survival. We sought to explore prognostic impact of EGCG in a cohort of lone cardiac ATTR patients. From the Florence Tuscan Regional Amyloid Centre database, we retrospectively selected ATTR patients treated with EGCG (675mg daily dose) for a minimum of 9 months, between March 2013 and December 2016...

AIMS: The purpose of the study was to describe the pattern of 99m Tc-labeled phosphate agents myocardial uptake by scintigraphy and explore its impact on left ventricular (LV) functions in transthyretin cardiac amyloidosis (TTR-CA). METHODS: Fifty patients with TTR-CA underwent 99m Tc- hydroxymethylene-diphosphonate (99m Tc-HMDP) scintigraphy and echocardiography with measure of LV thickness, longitudinal strain (LS), systolic and diastolic functions. Cardiac retention by scintigraphy was assessed by visual scoring and the heart/whole body (H/WB) ratio was calculated by dividing counts in the heart by counts in late whole-body images...

Congo Red staining is usually used in diagnosing amyloidosis, a pathology characterized by the storage of abnormal proteins in several human organs. When assessed on samples fixated in formalin and embended in paraffin, this staining can undergo several artefacts, causing diagnostic and interpretative difficulties due to its weak stainability and a consequent reduced visibility of the amyloid. These complications, in time, requested several variations of this staining technique, especially in clinical practice, while in the forensic field no protocols has ever been adapted to cadaveric samples, a material that is already characteristically burdened by a peculiar stainability...

BACKGROUND: Increasing recognition that transthyretin cardiac amyloidosis (ATTR-CA) is much more common than previously appreciated and the emergence of novel disease-modifying therapeutic agents have led to a paradigm shift in which ATTR-CA screening is considered in high-risk populations, such as patients with heart failure with preserved ejection fraction (HFpEF) or aortic stenosis. Radiation risk from 99m Tc-pyrophosphate (99m Tc-PYP) scintigraphy, a test with very high sensitivity and specificity for ATTR-CA, has not been previously determined...

Systemic amyloidosis is a rare disease involving multiple organs. It is difficult to establish diagnosis as the symptoms is diverse and non-specific. And without specific therapy the prognosis is very poor. We analyzed detailed clinical and laboratorial data of a 53-year-old male patient. The characteristic features included refractory pleural effusion, extraordinary hepatomegaly and cardiac failure. The illness lasted 9 months and therapy period spanned 4 months. Fine needle biopsy of liver, lung, heart, pancreas and kidney was performed...

To compare inversion time (TI) parameters, native T1, and extracellular volume (ECV) on cardiac magnetic resonance (CMR) imaging between patients with cardiac amyloidosis (CA) or hypertrophic cardiomyopathy (HCMP). Forty six patients with biopsy-confirmed CA and 30 patients with HCMP who underwent CMR were included. T1 and TI values were measured in the septum and cavity of the left ventricle on T1 mapping and TI scout images. TI values were selected at nulling point for each myocardium and blood pool. Native T1, ECV, and TI interval values were significantly different between the CA (1170...

Doppler echocardiogram provides not only structural information about heart chambers, valves and pericardium but also contributes to functional assessment. A unique feature of this assessment is its variability, not only due to heart disease course but also related to extracardiac conditions. We present a case of primary amyloidosis with two atypical characteristics: left ventricular outflow obstruction and low-grade diastolic dysfunction. Nevertheless, a more typical picture of cardiac amyloidosis was observed in the evolution of the disease coinciding with a second cardiac stressor, emphasizing the necessity of not focusing our attention exclusively to the heart...

The prognosis for patients with cardiac impairment due to AL-amyloid deposition and severe cardiac insufficiency is poor, with a survival median in the order of months. The classical treatment of AL-amyloidosis in combination with cardiac insufficiency is very poorly tolerated and the treatment of such patients is associated with considerably higher mortality than among other patients with AL-amyloidosis. If, however, patients with an isolated or another dominating cardiac impairment, without severe damage to other organs and tissues, have a heart transplant performed, their cardiovascular condition will significantly improve as a result, along with their ability to tolerate any kind of treatment for AL-amyloidosis including that using high-dose chemotherapy with a transplant of autologous hematopoietic stem cells...

Cardiovascular imaging has radically changed the management of patients with arrhythmogenic cardiomyopathies. This article focuses on the role of echocardiography and MRI in the diagnosis of these structural diseases. Cardiomyopathies with hypertrophic pattern (hypertrophic cardiomyopathy, restrictive cardiomyopathies, amyloidosis, Anderson-Fabry disease, and sarcoidosis), cardiomyopathies with dilated pattern, inflammatory cardiac diseases, and right ventricular arrhythmogenic cardiomyopathy are analyzed. Finally, anatomic predictors of arrhythmias and sudden cardiac death are discussed...

Cardiac amyloidosis (CA) comprises a heterogeneous group of medical conditions affecting the myocardium. It presents with proteinaceous infiltration with variable degrees of severity, prevalence and evolution. Despite this heterogeneity, erroneous protein folding is the common pathophysiologic process, yielding the formation of a single misfolded protein (monomer) that progressively evolves and ultimately forms amyloid fibers. Additionally, by seeding out from the organs of origin, intermediates called oligomers metastasize and restart the process...

Amyloidosis is a rare disease, which can affect various organs, such as the kidneys, heart, liver, respiratory and gastrointestinal tracts, and the nervous system. It still has a bad prognosis nowadays, despite chemotherapy and the new biotherapies. Its physiopathology corresponds to an irreversible, extracellular accumulation of fibrillous proteins in the tissues. Notwithstanding the fact that a clear diagnosis can be made with histology (of solid injured organs or a subcutaneous biopsy), magnetic resonance imaging (MRI) can show various advantages, especially to prove cardiac involvement, with great specificity and sensibility as well...

BACKGROUND: The hematologic response is critical in patients with light chain amyloidosis because a good response is known to improve organ response and overall survival. We present a retrospective analysis to compare the hematologic and organ response in patients who received bortezomib-based therapy before autologous stem cell transplantation (ASCT) versus those who received non-bortezomib-based therapy before ASCT and those who underwent ASCT at diagnosis. PATIENTS AND METHODS: Of a total of 63 patients who underwent ASCT for light chain amyloidosis, 34 received bortezomib-based therapy before ASCT (Bor-ASCT) and 29 did not receive bortezomib therapy (non-Bor-ASCT)...

BACKGROUND: Heart involvement is the most important prognostic determinant in AL amyloidosis patients. Echocardiography is a cornerstone for the diagnosis and provides important prognostic information. METHODS AND RESULTS: We studied 754 patients with AL amyloidosis who underwent echocardiographic assessment at the Mayo Clinic, including a Doppler-derived measurement of stroke volume (SV) within 30 days of their diagnosis to explore the prognostic role of echocardiographic variables in the context of a well-established soluble cardiac biomarker staging system...
