Heart transplantation in cardiac amyloidosis

It is known that the prognosis of patients affected by light-chain (AL) or transthyretin-related (TTR) amyloidosis is poor. TTR amyloidosis has usually shown a slower progression than AL amyloidosis, both hereditary TTR amyloidosis, where there is an inherited mutation in the DNA, and wild-type TTR amyloidosis, which usually affects the elderly. In this paper, the current literature about heart transplantation on cardiac amyloidosis patients is extensively reviewed. The two most frequent types of cardiac amyloidosis have been considered for heart transplantation: AL amyloidosis and wild-type TTR amyloidosis. According to this analysis, it is reasonable that heart transplantation may represent a valuable option in carefully selected patients. Moreover, it could improve prognosis, enabling autologous stem cell transplantation in the AL amyloidosis subgroup. In our humble opinion, it is mandatory to define a multidisciplinary approach to help select candidates to obtain the most effective results
