[Peripheral embolism in nonamyloidotic light-chain deposition cardiomyopathy].

Nonamyloidotic light-chain cardiomyopathy is a paraproteinemia-induced disorder. Unlike amyloidosis, light chain deposition may be reversible with appropriate treatment. We report a case of fatal light chain deposition disease manifested as cardiomyopathy, which was complicated by arterial embolism despite the maintenance of sinus rhythm.
