Objective To investigate the diagnostic value of real-time three-dimensional ultrasound in left atrial duct func-tion,booster pump function and storage function in patients with left ventricular noncompaction(LVNC).Methods A total of 180 patients with ultrasound manifestations of LVNC were selected(experimental group),and another 180 age-appropriate healthy people were selected(control group).A Philips Ie33 color Doppler ultrasound diagnostic instrument was used to capture 2D left atrial measurements and 3D full-volume images of left apical four-chamber sections,and the 3DQAdvanced tool of Qlab9.1 workstation was used for offline processing.Results There were no significant differences in Ve/Va,left ventricular ejection fraction,LVEDD,wall thickness and age between the two groups(P>0.05).The LAFV/BSA,left atrial dilatation index and LAEF of the experimental group were significantly higher than those of the control group,and the differences were statisti-cally significant.There were no significant differences in LAPASV/BSA,LACV/BSA and LAPEI between the experimental group and the control group(P>0.05).The LAASV/BSA of the experimental group and the control group were(8.73±3.92)ml/m2 and(5.53±3.92)ml/m2,and the LAAEI were(51.27±9.86)and(36.28±12.49),respectively,with no significant difference(P>0.05).LAASV/BSA and LAAEI in the experimental group were significantly higher than those in the control group,and the dif-ferences were statistically significant(P<0.05).The maximum filling volume/BSA of left atrium in experimental group and con-trol group was(22.58±8.64)ml/m2 and(18.06±4.76)ml/m2,respectively.The maximum filling volume of left atrium in ex-perimental group was higher than that in control group.Bland-Altman analysis plots showed that the intra-and inter-examiner agreement of LAVmax/max measurements met the requirements.Conclusion Real time three-dimensional ultrasound can ef-fectively evaluate left atrial duct function,booster pump function and storage function in patients with LVNC.
