Background: According to increased consumption of supplements especially during pregnancy and the teratogenic impact some they on evolution the vital systems of embryos. The purpose of this study to Improve the health of the fetus and prevention of cardiovascular abnormalities as the most common cause of infant mortality. We examined the effects of L-Arginine and L-NAME administration on fetal ...

AIM To assess whether four-dimensional (4D) spatiotemporal image correlation (STIC) can provide unique and novel information for diagnosing complex congenital heart diseases. METHODS A dynamic interactive 4D ultrasound system was used to examine 21 fetuses with complex congenital heart diseases and 25 fetuses with no apparent anomalies referred for prenatal diagnosis and management. Data acqu...

Fetal heart rate surveillance is a standard component of intrapartum care. The fetal heart rate can be evaluated using intermittent auscultation or electronic fetal monitoring. Research that has compared these 2 strategies found them to be equivalent with respect to long-term neonatal outcomes. The purpose of this clinical bulletin by the American College of Nurse-Midwives is to review the evid...

Molecular switches between the troponin T and I isoforms are known to occur in various conditions, but the results from studies of failing human hearts with various etiologies are contradictory and it is not certain whether troponin isoform changes occur. Therefore, the molecular switching of troponin isoforms during normal development and heart failure (HF) after myocardial infarction were inv...

The increased experience in interpretation of fetal echocardiographic images may change the accuracy of fetal echocardiography in diagnosing fetal heart defects. We thus decided to evaluate the specificity and the sensitivity of our fetal echocardiographic examinations in diagnosing congenital heart disease, focusing especially on the outcome of complex cardiac pathologies. Between October 1999...

OBJECTIVES The evaluation of hypoxia index (HI) in the prediction of abnormal fetal heart rate at delivery in uncomplicated pregnancies. MATERIAL AND METHODS The study group included 148 pregnant patients at term (69 patients with and 79 without brain sparing effect). The value of C/U ratio and HI was determined. Next, its value in predicting abnormal fetal heart rate during labor was evaluat...

Despite its recognized limitations, fetal heart rate monitoring is a mainstay of intrapartum care. Although the basic technology in standard electronic fetal monitors has changed little in recent decades, clinical behavior in response to heart rate monitoring has changed considerably. In addition to clearly defined nomenclature and clinical guidelines, there is an increased awareness that envir...

The clinical interpretation of fetal heart rate traces is a difficult task that has led to the development computerised assessment systems. These systems are limited by their inability to represent uncertainty. This paper describes the first stage in the development of a fu2zy expert system for fetal heart rate assessment. A preliminary evaluation study comparing the initial fuzzy system with t...

Umbilical artery\vein, middle cerebral artery, and ductus venosus Doppler velocimetry were performed at 33 weeks of gestation in the settings of an intrauterine growth restricted fetus during a heart rate deceleration. Interestingly, we recorded a sudden onset redistribution of fetal blood flow with fetal bradycardia. Spontaneous normalization of waveforms was observed once fetal heart rate ret...
