Systolic murmurs were detected in 22 (61%) of the 36 children with sickle cell anaemia (SCA) who completed the study. Cardiomegaly was detected in 14 (39%). Mean values of left and right ventricular dimensions were higher in SCA than in controls (p < 0.05). Left atrial chambers and aortic root dimensions followed the same pattern. The dilated cardiac chambers in SCA were not associated with any abnormality in systolic or diastolic left ventricular function nor with significant pulmonary hypertension.
