[Fetal echocardiography. A horizontal study of biometry and cardiac function in utero].

The anatomy and the cardiac growth in normal fetal heart was studied by real-time-directed M-mode ultrasound from the 19th gestation week until term. A correct fetal cardiac M-mode recording was obtained in 94 out of 144 women (65%). Echocardiographic variables were plotted against gestational age and respective correlation coefficients were determined by linear regression analysis. A comparison between the variables was studied by paired t-test. Left ventricular, right ventricular, left atrial and right atrial chamber size, interventricular septum thickness, right and left wall thickness, aortic and pulmonary diameter all increased linearly with age. Right ventricle (10.1 +/- 3.1) was slightly larger than left ventricle (9.2 +/- 2.8 mm) (p less than 0.001), the pulmonary artery (7.9 +/- 1.9 mm) was greater than the aorta (7.6 +/- 2 mm) (p less than 0.001), while no significant difference was noted between left atrium (10.8 +/- 3.5 mm) and right atrium (10.1 +/- 2.6 mm), right ventricular wall thickness (2.7 +/- 0.9 mm) and left ventricular wall thickness (3.0 +/- 1.1 mm). The ratios of left ventricular/right ventricular diameter, left atrial/right atrial and left atrial/aortic diameters, the relative wall thickness and arterial vessels diameters did not change significantly throughout the pregnancy. The ratio interventricular septum/posterior wall thickness was 1.14 +/- 0.36 and ratio of 1.5 or greater was found in 14.5% of the fetal normal heart. The ratio left atrial/aortic diameter was 1.32 +/- 0.21 and left atrium was significantly greater than aorta (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

[Antenatal assessment of intrauterine growth retardation by ultrasonic fetal biometry and non-stress fetal heart rate testing].

This paper presented the results of ultrasonic measurements and non-stress tests (NST) in 60 light-for-dates (LFD) fetuses. BPD, FFL, mean abdominal diameter (MAD), HC/AC ratio and EFW were used as the parameters and the rates of LFD detection were evaluated. The effects of antenatal therapy for IUGR were assessed by the analyses of normal deviate values of EFW in treated and untreated groups. Qualitative and quantitative analyses of NST findings were presented. As to the detection of LFD, sensitivity values for MAD and EFW were 66.7% and 53.8% respectively; meanwhile both parameters disclosed the same degree of accuracy, as high as 90.0%. EFW values were well correlated to the actual birth weight and the mean estimation error was 147g. No evident increase in the normal deviate value for EFW was noted in any type of therapy. On the other hand, the value decreased in the untreated EPH gestosis group. The incidences of non-reactive and fetal distress patterns for NST in the LFD group were significantly higher than those in the normal control group. In particular, the high rate of mild variable deceleration and dip 0 was characteristic of IUGR. Quantitative analysis of NST also revealed a high rate (38.4%) non-reactive pattern. However, it showed a slight decrease in the amplitude and frequency of LTV.

[Ultrasonic biometry of the fetal crown-rump length between 7 and 20 weeks gestation (author's transl)].

In 370 examinations on 258 patients with known gestational age crown-rump length (CRL) of the fetus was determined by sonar between 7 and 20 weeks. From the results the mean and "2 SD" limits of CRL were derived by means of a non linear regression analysis. The measurements were further analysed to determine gestational age for a given CRL. Besides a velocity curve of CRL growth was calculated. It showed a maximum of 1.8 mm per day at 14 weeks. It was confirmated that sonar measurements of crown-rump length are very useful to estimate maturity of the fetus. The accuracy was found to be best in early measurements (+/-6 days at 7 weeks -+/-11 days at 20 weeks). In regard to clinical decisions reading errors have to be taken into consideration. To avoid them control examinations should be carried out.

Foetal twin ultrasound biometry.

Biparietal diameter growth differs considerably in the twin gestation compared to the singleton gestation; thus the use of a specific standard is recommended. A shift toward lower values is noticed in monochorial twins. In the case of the abdominal diameter growth, instead, no significant difference is found between twins and singletons.
