[Cardiac amyloidosis : simplifying the diagnosis of a complex disease].

Amyloidosis is a systemic infiltrative disease characterized by deposition of misfolded proteins in tissues, notably affecting the heart. According to type of protein, various types are known with the most prevalent being light-chain and transthyretin amyloidosis. Prognosis is dismal with progression to severe heart failure without disease-modifying treatment. Latter having dramatically improved over the last decade, prompt diagnosis is of paramount importance. Recognition of early signs followed by multidisciplinary approach is essential for optimal patient management.
