A cardiac biopsy involves taking a small sample of heart tissue that the doctor examines under the microscope. A technetium pyrophosphate scan is similar to an MRI in that it gives a picture of the heart. Endomyocardial Biopsy Characterization of Heart Failure With Preserved Ejection Fraction and Prevalence of Cardiac Amyloidosis In this large, prospective myocardial tissue analysis of HFpEF, myocardial fibrosis and hypertrophy were common, CD68+ inflammation was increased, and CA prevalence was 14%. Echocardiogram and cardiac magnetic resonance imaging can support a diagnosis of infiltrative cardiomyopathy but cannot diagnose amyloidosis or distinguish types of amyloidosis. Laboratory studies showing plasma cell dyscrasia suggest AL. With AL, biopsy is mandatory for diagnosis. Biopsy A tissue sample may be taken and checked for signs of amyloidosis.
