Transthyretin cardiac amyloidosis is a restrictive cardiomyopathy caused by extracellular deposition in the heart of amyloid fibrils derived from plasma transthyretin (ATTR), either in its hereditary (ATTRh) or acquired (ATTRwt) forms. Cardiac amyloidosis has a very poor prognosis if therapy is not started promptly. Therefore, it is very important to recognize cardiac amyloidosis early in order to immediately start a treatment capable of modifying the prognosis. Treatment of cardiac amyloidosis is not easy, often requiring a multidisciplinary team. New RNA-interfering drugs (such as patisiran) have been devised and are effective in the treatment of ATTRh amyloidosis. Tafamidis (a stabilizer of the native tetramer structure of TTR) is recommended to treat patients with genetic testing-proven hereditary hTTR-cardiomyopathy or wild-type TTR cardiomyopathy and NYHA Class I or II to reduce symptoms, CV hospitalization and mortality (Class I, level of evidence B). Patisiran should be considered in ATTRh cardiomyopathy with polyneuropathy. Thus, this review is intended to be a simple practical guide for the treatment of ATTR cardiac amyloidosis.

Abstract

Transthyretin cardiac amyloidosis is a restrictive cardiomyopathy caused by extracellular deposition in the heart of amyloid fibrils derived from plasma transthyretin (ATTR), either in its hereditary (ATTRh) or acquired (ATTRwt) forms. Cardiac amyloidosis has a very poor prognosis if therapy is not started promptly. Therefore, it is very important to recognize cardiac amyloidosis early in order to immediately start a treatment capable of modifying the prognosis. Treatment of cardiac amyloidosis is not easy, often requiring a multidisciplinary team. New RNA-interfering drugs (such as patisiran) have been devised and are effective in the treatment of ATTRh amyloidosis. Tafamidis (a stabilizer of the native tetramer structure of TTR) is recommended to treat patients with genetic testing-proven hereditary hTTR-cardiomyopathy or wild-type TTR cardiomyopathy and NYHA Class I or II to reduce symptoms, CV hospitalization and mortality (Class I, level of evidence B). Patisiran should be considered in ATTRh cardiomyopathy with polyneuropathy. Thus, this review is intended to be a simple practical guide for the treatment of ATTR cardiac amyloidosis.
