REDONDO M, Francisca; GONZALEZ E, Patricio y RAMIREZ N, Alfredo. Myocardial pyrophosphate uptake in cardiac amyloidosis. Rev. méd. Chile [online]. 2002, vol.130, n.3, pp. 315-318. ISSN 0034-9887. http://dx.doi.org/10.4067/S0034-98872002000300011.
We report a previously healthy 73 years old woman, who was hospitalised with increasing dyspnea and signs of congestive heart failure. Echocardiography showed a normal left ventricular cavity with increased echogenicity of its walls and severe pulmonary hypertension. A lung ventilation/perfusion scintigraphy concluded that there was a low probability for pulmonary embolism. Coronary angiography was normal. A restrictive cardiomyopathy due to amyloid deposits was suspected. Myocardial pyrophosphate scintigraphy showed intense pyrophosphate uptake in the left ventricle wall. An abdominal fat tissue biopsy was positive for amyloid deposits (Rev Méd Chile 2002; 130: 315-8)
