Aportes del ecocardiograma y las técnicas de deformación miocárdica en la amiloidosis cardíaca. Bases de la técnica y hallazgos de utilidad diagnóstica

Cardiac amyloidosis is an infiltrative restrictive cardiomyopathy secondary to extracellular amyloid deposition. Di - fferent cardiac imaging techniques allow noninvasive evaluation. Echocardiography plays a central role in diagnos-tic and prognostic evaluation and helps to guide treatment. The aim of this review is to describe the different tools provided by echocardiography, with emphasis on speckle tracking strain and to describe its role in the diagnosis of this pathology.
