Abstract: Objective To assess left atrial reservoir function based on left atrial filling volume,the left atrial expansion index and left atrial ejection fraction (LAEF) were measured in patients with left ventricular non-compaction cardiomyopathy (LVNC),using real-time three-dimensional echocardiography (RT3DE),to determine the value for LVNC diagnosis.Methods The study included 20 patients diagnosed with LVNC,including 3 patients,aged 4-16 years;8 patients,aged 17-35 years;9 patients,aged 36-55 years;and 20 healthy age-matched control subjects.All patients underwent two-dimensional echocardiography and RT3DE.Results Two-dimensional echocardiography showed no differences between groups (P ＞ 0.05).RT3DE analysis showed that the average left atrial filling volume/BSA,left atrial expansion index,and LAEF were significantly higher in the LVNC group.Conclusion LVNC is associated with increased left atrial reservoir function.RT3DE shows promise for the diagnosis of LVNC.
