Characterizing left ventricular systolic dysfunction in sickle cell disease: three contrasting case reports

This case series presents the first attempt to characterize the aetiology of LVSD in SCD. We identified three phenotypes: iron-overload cardiomyopathy, non-ischaemic DCM, and ischaemic DCM. These contrasting cases highlight the significance of understanding the underlying pathology in determining individualized treatment plans for these high-risk patients. We discuss the role of cardiac MRI (CMR) in characterizing LV dysfunction, and we believe that this case series will form the basis of prospective studies to further delineate the pathophysiology of LVSD in SCD.
