Long-Axis Left Ventricular and Left Atrial Dysfunction in Friedreich Ataxia with Normal Ejection Fraction – Global Longitudinal Strain Versus Tissue Doppler Imaging Velocities

D. Jackson, R. Hassam, L. Donelan, R. Peverill, Heart, Lung and Circulation, Volume 25, Supplement 2, August 2016, Page S80, ISSN 1443-9506, http://dx.doi.org/10.1016/j.hlc.2016.06.185.

In FRDA there are complex interrelationships between global longitudinal strain and tissue Doppler imaging mitral annular velocities, but the strongest correlate of the severity of the genetic abnormality (GAA1) is atrial contraction.
