Abstract:

Objective

To evaluate the application value of fetal intelligent navigation echocardiography in the acquisition and display of the critical section of common fetal conotruncal defects (CTD).

Methods

From January to September 2018, 65 fetuses with fetal CTD were diagnosed by fetal echocardiography at Department of Ultrasound, Sir Run Run Shaw Hospital, Zhejiang University College of Medicine, including 31 fetuses with tetralogy of Fallot (TOF), 24 with complete transposition of great arteries (TGA), and 10 with double-outlet right ventricle (DORV). Fetal cardiac spatio-temporal image correlation (STIC) volume datasets were acquired with four-chamber cardiac section as the initial section. Then, the three-dimensional STIC volume data were analyzed with fetal intelligent navigation echocardiography (FINE) analysis software, and the success rates of volume acquisition at different locations of the initial apex were compared. The success rates of fetal section acquisition and diagnostic coincidence rates for TOF, DORV, and TGA, and the overall results for all CTD fetuses were compared by rate or percentage, and the repeatability of FINE technique was analyzed by the chi-square test.

Results

A total of 337 volumetric data were acquired at any position of the apex in 65 fetuses, of which 245 could be analyzed and 226 were successfully analyzed. The success rate was 92.24%. The coincidence rates for diagnoses of TOF, TGA, DORV, and CTD were 77.42%, 80.65%, 87.50%, and 87.50%, and 60.00%, 70.00%, 78.46%, and 81.54%, respectively, in the first time and one week later. A total of 207 volumetric data were acquired from group A (fetal apex located between the 11- and 1-o’clock positions), of which 192 could be analyzed and 182 were successfully analyzed, with a success rate of 94.79%. The diagnosis coincidence rates for TOF, TGA, DORV, and CTD in the first time and one week later were 94.12%, 88.24%, 93.75%, and 87.50%, and 66.67%, 66.67%, 89.74%, and 84.61%, respectively. There was no statistical difference between the diagnosis coincidence rates in the first time and one week later (P>0.05).

Conclusion

FINE could be useful in the diagnosis of fetal CTD with high repeatability. It has important potentials in standardized fetal image acquisition and analysis, remote consultation, and training and teaching of fetal echocardiography.
