Abstract
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. 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. 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 patient...Continue Reading
