Department of Cardiology, Emergency Institute for Cardiovascular Diseases 'Prof. Dr. C. C. Iliescu', 3rd Cardiology Department, 258 Fundeni Street, Bucharest, 022328, Romania.

Cardiac amyloidosis is a restrictive cardiomyopathy determined by the accumulation of amyloid, which is represented by misfolded protein fragments in the cardiac extracellular space. The main classification of systemic amyloidosis is determined by the amyloid precursor proteins causing a very heterogeneous disease spectrum, but the main types of amyloidosis involving the heart are light chain (AL) and transthyretin amyloidosis (ATTR). AL, in which the amyloid precursor is represented by misfolded immunoglobulin light chains, can involve almost any system carrying the worst prognosis among amyloidosis patients. Read More

Practical recommendations for the diagnosis and management of transthyretin cardiac amyloidosis.

Heart Fail Rev 2021 Jul 15;26(4):861-879. Epub 2021 Jan 15.

Department of Clinical Therapeutics, National and Kapodistrian University of Athens, Athens, Greece.

Cardiac amyloidosis (CA) is an infiltrative restrictive cardiomyopathy caused by accumulation in the heart interstitium of amyloid fibrils formed by misfolded proteins. Most common CA types are light chain amyloidosis (AL) caused by monoclonal immunoglobulin light chains and transthyretin amyloidosis (ATTR) caused by either mutated or wild-type transthyretin aggregates. Previously considered a rare disease, CA is increasingly recognized among patients who may be misdiagnosed as undifferentiated heart failure with preserved ejection fraction (HFPEF), paradoxical low-flow/low-gradient aortic stenosis, or otherwise unexplained left ventricular hypertrophy.

Endomyocardiofibrosis: A Systematic Review.

Curr Probl Cardiol 2021 Apr 26;46(4):100784. Epub 2020 Dec 26.

Department of Cardiology and Heart Failure Unit, Sanatorio Güemes, Buenos Aires, Argentina.

Endomyocardiofibrosis was described first time in Uganda as an infrequent restrictive cardiomyopathy with a poor prognosis, characterized by fibrosis of the ventricular subendocardium and severe restrictive physiology leading to difficult therapeutic management and frequently associated with hypereosinophilic syndrome. Its higher prevalence in the tropics and its relationship in some cases with hypereosinophilic endocarditis has led to the search for genetic, infectious, autoimmune and nutritional causes, but its etiology remains unclear. It is a rare cardiomyopathy, difficult to diagnose and with a nonexistent effective treatment. Read More

[Transthyretin cardiac amyloidosis].

Rev Med Interne 2020 Oct 18;41(10):673-683. Epub 2020 Aug 18.

Centre de Référence National des Amyloses Cardiaques et Réseau Amylose Mondor, Service de Cardiologie, CHU Henri Mondor, 51 Avenue du Maréchal de Lattre de Tassigny, 94010 Créteil, France.

Transthyretin (TTR) cardiac amyloidosis results from the dissociation of the tetrameric, liver-synthetized transport protein, either because of a mutation (hereditary CA), or spontaneously due to ageing (wild type CA). Monomers self-associate into amyloid fibrils within the myocardium, causing heart failure, arrhythmias and conduction defects. This overlooked disease must be recognized in case of unexplained increased thickness of the myocardium, particularly in subjects of African descent, in patients with heart failure and preserved ejection fraction, and in those with aortic stenosis.
