A 42-year-old man presented with orthopnea, paroxysmal nocturnal dyspnea, and ascites, which had progressed for the previous two months. Electrocardiogram was low voltage. Transthoracic echocardiography showed concentric left ventricular hypertrophy and increased brightness and speckling pattern in the ventricular septum, consistent with amyloidosis. Cardiac magnetic resonance imaging confirmed the echocardiographic findings, and gingival biopsy was positive for amyloidosis.
