Primary Systemic Amyloidosis Presenting with Advanced Heart Failure: Finalist, Cardiology in Review Fellowship/Residency Clinical Case Contest

Abstract

Primary systemic amyloidosis (AL) is a rare, sporadic disease caused by deposition of immunoglobulin light chains in various tissues; symptoms vary based on which organs are infiltrated by the amyloid fibrils. Cardiac involvement occurs in up to 50 of patients with primary amyloidosis and is associated with a very poor prognosis. We report a case of a 57-year-old black man who presented with symptoms consistent with congestive heart failure. He was later found to have primary systemic amyloidosis, confirmed by abdominal fat pad biopsy.
