Novel Atrial Deformation Changes in Duchenne Cardiomyopathy

BACKGROUND: Although progressive myocardial fibrosis and worsening ventricular function is well characterized in Duchenne muscular dystrophy (DMD), changes in atrial mechanics are unknown. The objectives of this study are to evaluate changes in left atrial (LA) deformation and its association with left ventricular (LV) deformation, systolic function and fibrosis. METHODS: This is a retrospective (2004 to 2019) single …
