Abstract

© 2017 Elsevier Inc. To differentiate left ventricle non-compaction (LVNC) from hypertrabeculated myocardium due to LV remodeling in β-thalassemia major (β-TM) patients, cardiac magnetic resonance (CMR) images of 38 β-TM patients and 10 LVNC patients were compared using 3 diagnostic criteria: ratio of diastolic segmental non-compacted to compacted myocardium (NC/C ratio) >  2.5, percentage of non-compacted LV mass (NC-LVM%) >  20% and >  25% of global LV mass. Specificity of NC/C ratio of >  2.5 was the lowest (58%) and of NC-LVM% of >  25% the highest (93%). A NC-LVM% >  20% showed sensitivity 100% and specificity 87%. Disease differentiation depends on the selected CMR criterion and is better with NC-LVM%.
