Abstract
BACKGROUND: Data on children with left ventricular non-compaction (LVNC) is sparse. The purpose of this study was to evaluate its clinical profiles in a population of Chinese children. METHODS: From January 2010 to March 2016, consecutive Chinese children (aged <18 years) with LVNC diagnosed by cardiovascular magnetic resonance (CMR) were prospectively recruited at Fuwai Hospital. RESULTS: A total of 41 Chinese children (male: 28%; mean age: 14±4years) were included in this study. Left ventricular non-compaction was not detected in 13 (32%) patients at initial echocardiographic evaluation. Congenital heart disease (CHD) was found in 11 (27%) patients. Four (10%) patients had Wolff-Parkinson-White (WPW) syndrome. Mean left ventricular ejection fraction (LVEF) was 41±15%. Late gadolinium enhancement (LGE) was detected in eight (20%) subjects. During a mean follow-up of 2.9 years, four (9%) patients died or received heart transplantation. These patients had lower systolic blood pressure (91±10 vs. 108±14mmHg; p=0.02), diastolic blood pressure (57±7 vs. 68±8mmHg; p=0.007) and LVEF (19±7 vs. 44±12%; p=0.002) than the survivors. In addition, advanced heart failure (100% vs. 16%; p=0.002) and LGE (50% vs. 5%; p=0.04) were detected more in these subjects. CONCLUSIONS: Left ventricular non-compaction is easily overlooked at echocardiographic assessment. Congenital heart disease and WPW syndrome were relatively common in LVNC children. The prognosis of children with LVNC seemed to be better than previous studies reported, and its long-term prognosis needs to be further investigated.
