Light-Chain Cardiac Amyloidosis: A Case Report and Review of the Literature

Abstract Background: Light-chain (AL) cardiac amyloidosis is a rare cardiomyopathy associated with poor prognosis. Due to the advances of imaging technology, cardiac amyloidosis can be now sufficiently diagnosed without myocardial biopsy. Case presentation: This study reports a 69-year-old female who was admitted with chest distress, abdominal distension, anorexia, resistant hypotension, oliguria, and hyponatremia. The patient was confirmed as AL cardiac amyloidosis with the aid of cardiac MR 2 years after symptom onset. The patient received palliative care due to the end stage of the disease. Conclusions: Early diagnosis by cardiac imaging and etiology-oriented treatment are of importance to improve prognosis of AL cardiac amyloidosis.
