[III-JCKEOP02-05] Fetal Echocardiography Characteristics in Vietnam Population
BACKGROUND:
To evaluate the incidence of fetal cardiac abnormalities and to establish normative reference ranges of fetal cardiac characteristics in Vietnamese population.
METHODS:
A cross_sectional study was undertaken on pregnancies examined at Thu Duc district hospital, Ho Chi Minh city from November 2012 to April 2013.
RESULTS:
Two hundred and twenty pregnant women were enrolled in this study.
1. Characteristics: mothers’ mean age (years): 30.3 + 5.0 ; Mean gestational age (weeks) : 33.6 + 4.5 ; Population characteristics: intrauterine growth retardation (1.7%); diabetes (10.1%); genetic mutation (0.8%); abnormalities in routines echo scan (4.2%); twins (1.7%); previous child with congenital heart disease (0.8%); fetal tachycardia (0.8%); screening (78.2%).
2. Fetal cardiac characteristics: heart chest ratio (CTAR, %) = 31.4 + 4.8 . The mean cardiac dimension on 2D (mm): foramen oval = 4.9 + 1.4; mitral valve = 9.9 + 2.1; tricuspid valve = 10.4 + 2.4; aortic valve = 6.3 + 1.4; pulmonary valve annulus = 7.9 + 1.8; pulmonary trunk = 7.8+ 1.9; right pulmonary artery = 3.9 + 1.0 ; left pulmonary artery = 3.9 + 0.9 ; aortic isthmus = 4.9 + 1.0. The mean velocities : aortic valve = 0.66 + 0.15(0.35-1.00); pulmonary valve = 0.61 + 0.14); aortic arch = 0.74 + 0.21
3.one fetus with ventricular septal defect (0.45%), one fetus with supra ventricular tachycardia (0.45%), one with sinusbradycardia (0.45%) and one with coarctaion (0.45%).
CONCLUSIONS:
This is the first report on normal ranges of fetal cardiac dimensions especially in the third trimester in Vietnam.
