Abstract/OtherAbstract:
OBJECTIVE: To establish normative reference ranges of fetal cardiac dimensions derived from volume datasets of cardio-STIC-M (spatio-temporal image correlation with M-mode display) METHODS: A cross-sectional study was undertaken on singleton pregnancies with accurate gestational age and normal fetuses. Volume datasets of cardio-STICs were acquired by experienced sonographers with a high-resolution machine, which were maneuvered to obtain a four chamber-view with exactly horizontal interventricular septum. Cardiac dimensions were measured in STIC-M-mode using 4D-View version 9. RESULTS: A total of 657 measurements, 15-37 per week of gestation, were performed. Normal reference ranges for biventricular outer dimension, left and right ventricular inner dimension, left and right ventricular wall thickness, interventricular septum thickness, and left to right ventricular width ratio were constructed based on best-fit equations as a function of gestational age, fetal head circumference and biparietal diameter. Additionally, left and right ventricular shortening fractions were also established based on linear equation. Thirty-four volume datasets of fetal abnormal hearts were also separately assessed, suggesting that the assessments may probably be helpful. CONCLUSION: This is the first report on normal ranges of fetal cardiac dimensions constructed using new cardio-STIC M-mode technology, a theoretically most reliable method. The preliminary evaluation suggests that these reference ranges may be a useful tool in assessment of fetal cardiac abnormalities. Copyright © 2011 ISUOG. Published by John Wiley & Sons, Ltd.
