摘要

Amyloidosis is a multisystem disease that is characterized by deposition of fibrils in extracellular tissue,which mainly involves the kidney,heart,and autonomic nervous system.Two types of amyloidosis typically infiltrate the heart,including immunoglobulin light-chain(AL)and amyloid transthyretin(ATTR).ATTR is further subdivided into wild-type ATTR and variant ATTR caused by point mutations in the TTR gene.[1]Wild-type ATTR is considered as not uncommon in older patients with heart failure.Recently,a comprehensive set of consensus recommendations for the suspicion and diagnosis of ATTR was published,with particular focus on the combined application of noninvasive methods.[2]We present here a case of wild-type TTR cardiac amyloidosis(ATTRwt-CA),which was diagnosed by noninvasive modalities,and provide an overview of the recommended diagnostic approach of CA.Furthermore,to the best of our knowledge,this is the first Chinese case of ATTRwt-CA reported to date.
