ABSTRACT

Recent studies suggest that the prevalence of wild type transthyretin cardiomyopathy (wATTR-CM) is substantially higher than previously appreciated in older adults with heart failure. Advances in nuclear imaging using bone avid radiotracers permit diagnosis of transthyretin-related cardiomyopathy (ATTR-CM) without a tissue biopsy. We describe two wATTR-CM cases that were diagnosed using noninvasive methods and demonstrate this diagnostic approach for transthyretin-related cardiomyopathy.

Keywords: amyloid, cardiomyopathy
