[Case of cardiac amyloidosis associated with IgG-K multiple myeloma in the framework of restrictive myocardiopathy].
Primary amyloidosis, due to amassing of fragments of light chains of IgG, often causes cardiac involvement. We describe a 65-year-old woman with multiple myeloma efficaciously treated with chemotherapy. Amyloidosis had been supported by myelic biopsy. The patient came to our observation because of right heart failure, hypotension and syncope: she was treated with a dopamine i.v. and was in cachectic status. She had a moderate pericardial effusion. ECG showed reduction of QRS amplitude, I degree atrioventricular block, posterior fascicular and right bundle branch block. Right cardiac catheterization showed a restrictive situation. After 1 week exitus occurred by asystole. In this case, there were other involvements by amyloidosis, besides the cardia one: that of autonomic nervous system and, probably, surrenal.
