Cardiac Amyloidosis (CA) is characterized by a long subclinical phase characterized by deposition of amyloid fibrils in atria, valves and walls of ventricles. Longitudinal dysfunction of the left ventricle (LV) with preserved ejection fraction (EF) is the early phase of CA. Longitudinal dysfunction mainly involves the LV basal and middle segments with less involvement of the distal segments (apical sparing). Strain echocardiography (STE) measures myocardial deformation. The technique has been shown to be sensitive for early detection of impaired systolic function and for the study of CA. Additionally, cardiac efficiency (myocardial work) can be derived from myocardial strain data analysis. In the year 2018, "RNA interferences" (patisiran and inotersen) were included in the list of compassionate therapeutic use programs for exclusive use for the treatment of adult patients with hereditary amyloidosis neuropathy. The aim of our study is to evaluate the morpho-functional modifications with RNA interferences.
1. Patients will undergo clinical and laboratory assessment, as well as imaging tests, at the discretion of the attending cardiologist and will be referred at their discretion to perform cardiac mapping using 99mTc-PYP. 2. On the day of the examination, the examiner will be admitted to the Office of Nuclear Medicine and will be admitted to administrative. Before conducting the test, the subject will undergo a brief interview by a physician, receive an explanation of the study and, if agreed, sign an agreement to perform a further examination on the CZT camera. 3. The patient will, as is customary, be installed on Vanflon 22 G periphery, through which a 15 millikiric (mCi) of
Cardiac amyloidosis is a multi-organ syndrome, which usually presents as restrictive cardiomyopathy (RCM). Transthyretin (TTR) amyloidosis (or ATTR) is a subtype of amyloidosis which frequently involves heart. Cardiac ATTR, though infrequently diagnosed during lifetime, may represent a prevalent cause of RCM, especially in elderly. Several medications that can limit progression of the disease are currently under investigation. Presently the golden standard for diagnosis of ATTR is endomyocardial biopsy (EMB) which may entail severe adverse complications causing under-diagnosis of ATTR. Several papers support the evidence that Tc99m-labeled tracers can be used to detect myocardial deposits of TTR amyloid. It was suggested that Tc99m scintigraphy might be a highly sensitive diagnostic tool for cardiac ATTR. In this study the patients with otherwise unexplained cardiomyopathy or heart block will undergo Tc99m scan, which will establish the incidence of this largely underdiagnosed condition in the population.
Efficacy of Methylene blue mediated Photodynamic therapy for primary localized cutaneous amyloidosis treatment in Asians, pilot study.
Purpose of this study is to determine whether keeping SAA on normal or near normal level will delay progression of renal failure in patients with amyloidosis secondary to FMF.
