title: Primary systemic amyloidosis presenting as constrictive pericarditis.
abstract: The most frequent presentation of cardiac amyloidosis is with endomyocardial deposition, and resultant restrictive cardiomyopathy. We present a case of primary systemic amyloidosis causing constrictive pericarditis (CP) and congestive heart failure without clinical evidence of endomyocardial deposition. A comprehensive evaluation by noninvasive and invasive studies facilitated the differentiation of CP from restrictive cardiomyopathy and the patient was effectively treated with pericardectomy. To our knowledge, this is the first documented case of primary systemic amyloidosis causing selective CP with successful antemortem diagnosis and treatment in a young man.
