POVAR ECHEVERRIA, M. et al. Non-invasive diagnosis of cardiac amyloidosis due to transthyretin. Case report. Anales Sis San Navarra [online]. 2018, vol.41, n.2, pp.263-267. ISSN 1137-6627.  https://dx.doi.org/10.23938/assn.0295.

Amyloidosis due to deposits of transthyretin (ATTR) is currently considered the most frequent form of cardiac amyloidosis and its incidence is increasing thanks to the advances in diagnostic imaging techniques. Some non-invasive diagnostic criteria have recently been published on this entity that due to the development of new drugs for the specific treatment of cardiac ATTR, have prognostic and therapeutic implications. That is why cardiac ATTR could cease to be a rare disease and become a frequent one, and become potentially treatable instead of incurable.

We present the case of an 80-year-old male diagnosed with non-hereditary cardiac ATTR by means of gammagraphy with 99mTc diphosfonate scintigraphy (99mTc-DPD) following the new criteria of non-invasive diagnosis.

Keywords : Amyloidosis; Transthyretin; Cardiomiopathy; Heart failure; ^99mTc-DPD scintigraphy.
