Use of tissue Doppler imaging to identify and manage systemic diseases

Abstract

In systemic diseases such as amyloidosis, sarcoidosis, Friedreich's ataxia, Fabry's disease and muscular dystrophy the clinician has to judge the presence and the amount of cardiac involvement. In most of these patients conventional echocardiographic parameters are not sensitive enough to detect sub-clinical dysfunction. Tissue Doppler imaging and in addition strain rate imaging has proven to be very sensitive for the assessment of myocardial dysfunction. This review explores the impact of these new techniques to identify and to manage cardiac aspects of the different systemic diseases.
