ABSTRACT = {<b>Objectives:</b> Incidence of sickle cell disease (SCD) in Ireland has dramatically increased. Disease
survival has also steadily improved however cardiovascular manifestations remain important causes
of morbidity. These include reports of left ventricular hypertrabeculation (LVHT)/noncompaction.
We sought to investigate the prevalence of LVHT among a large cohort of children with SCD.<br/>
<b>Methods:</b> We retrospectively reviewed the records of all patients with a diagnosis of SCD who had
undergone surveillance echocardiography at Our Lady’s Children’s Hospital Crumlin (OLCHC) from
1998 to 2015. Demographics, hemoglobin phenotype and treatment information was recorded. LV
systolic function, evidence of LVHT, and possible pulmonary arterial hypertension was assessed.<br/>
<b>Results:</b> Two hundred thirty-six patients had echocardiograms available for interpretation. One
hundred twenty-one (51.3%) were female; mean age was 11.3 years (± 4.1 years). Twenty-six
patients (11%) had features of LVHT on echocardiography. Eleven patients (4.7%) had borderline
features of LVHT. Mean LVEDD across the whole cohort was 4.2 ± 0.69 cm, LVEDD z-score of
1.44 ± 1.9, and mean LVSF was 37.3% ± 15.7%. There were no significant differences in terms of
age, LVEDD, LVEDD z-score, or LVSF between patients with and those without LVHT.<br/>
<b>Conclusions:</b> The prevalence of LVHT/noncompaction in children with SCD is lower than the
adult population and LV systolic function is well preserved throughout our patient group. The
mechanism behind the development of LVHT in this population remains speculative. Further work
is required in this field. Sickle cell patients require longitudinal evaluation to ascertain changes in
left ventricular function and the presence of LVHT/noncompaction.},
