Touzet, G — y Herrera, M. La CC es la principal causa de mortalidad infantil, con una incidencia estimada de aproximadamente 4 a 13 por nacidos vivos Este tipo de hallazgo de manera aislada, representa una variante de la normalidad47, La frecuencia normal es de a latidos por minuto lpm.

Una bradicardia leve puede ser observada de manera transitoria en fetos normales en el segundo trimestre. En el examen ideal, todos los cortes de los tractos de salida se pueden obtener con relativa facilidad. Por lo tanto, es recomendable estar familiarizado con todos los cortes.

Debe documentarse la continuidad entre el tabique ventricular y la pared anterior de este vaso, la aorta. Es posible delinear la aorta en su arco, desde donde se originan tres arterias dentro del cuello. En este nivel, como se ve en la Figura 6, la vena cava superior se ve a menudo a la derecha de la aorta. Este corte es similar al corte de 3V, descrito por Yoo et al. La rama derecha de la arteria pulmonar se desprende primero y la rama izquierda posteriormente. Yoo et al. De izquierda a derecha, los vasos son la arteria pulmonar, la arteria aorta y la vena cava superior.

Biometría fetal: edad gestacional, evaluación del tamaño y estimación del peso fetal

Screening for, and adequate management of, fetal growth abnormalities are essential components of antenatal care, and fetal ultrasound plays a key role in assessment of these conditions. These biometric measurements can be used to estimate fetal weight EFW using various different formulae1. It is important to differentiate between the concept of fetal size at a given timepoint and fetal growth, the latter being a dynamic process, the assessment of which requires at least two ultrasound scans separated in time. Maternal history and symptoms, amniotic fluid assessment and Doppler velocimetry can provide additional information that may be used to identify fetuses at risk of adverse pregnancy outcome. Except for pregnancies arising from assisted reproductive technology, the date of conception cannot be determined precisely. Clinically, most pregnancies are dated by the last menstrual period, though this may sometimes be uncertain or unreliable.
