Reported herein is an autopsy case of familial amyloidotic polyneuropathy (FAP) with cardiac liver cirrhosis associated with amyloid cardiomyopathy after liver transplantation. At 47 years of age a Japanese woman with a transthyretin Val30Met mutation and sensorimotor polyneuropathy underwent liver transplantation; no postoperative deterioration related to the graft or polyneuropathy occurred. However, cardiovascular dysfunction associated with amyloid deposition gradually worsened. Pacemaker implantation and diuretics were ineffective against the heart failure; 10 years after transplantation the patient died. Autopsy revealed massive pleural and pericardial effusions and amyloid cardiomyopathy, especially in the right atrium and cardiac conduction system. Amyloid deposition was slight in all organs except the heart, but liver cirrhosis with reversed lobulation and centrilobular hemorrhagic necrosis was prominent. There was no histological evidence for chronic liver graft rejection. These findings suggest that liver transplantation effectively stopped amyloid deposition and ameliorated clinical FAP symptoms but that amyloid cardiomyopathy after liver transplantation in advanced clinical stages may lead to severe congestive heart failure and cardiac liver cirrhosis.
