Abstract：Objective To explore the value of three‐dimensional echocardiography for assessment of ventricular function and synchronicity in functional single ventricle (FSV) .Methods 3DE data were acquired in 20 patients with FSV and 20 age‐matched normal children ,then ,end‐diastolic volume (EDV) ,end‐systolic volume (ESV) ,ejection fraction (EF) ,ex‐cursion ,ball excursion and indexes of ventricular synchronicity were compared by Q‐lab software .Results ① EDV and ESV were significantly higher and EF were significant significantly lower in FSV group ;②Excursion of various segments was lower in FSV group ; ③ The values of Tmsv16‐SD , Tmsv16‐SD% , Tmsv16‐Dif , Tmsv16‐Dif% , Tmsv12‐SD , Tmsv12‐SD% ,Tmsv12‐Dif , Tmsv12‐Dif% , Tmsv6‐SD% , Tmsv6‐SD% , Tmsv6‐Dif , Tmsv6‐Dif% were significantly prolonged in FSV ;④Most indexes of LV synchronicity had good correlation with ventricular function ,especially Tmsv16‐SD% ( r =‐0 .774 ,P<0.001) .Conclusion Tmsv16‐SD% ,best correlated with ventricular function can provide an opti‐mal index in assessing ventricular synchronicity .
