Anatomy of the heart The atrioventricular valves are seen closed with the tricuspid valve on the right between the right atrium and rt ventricle, the bicuspid or mitral valve is the valve on the left between the left atrium and left ventricle.

To assess fetal cardiac anatomy, a disciplined approach is necessary and optimization of the 2-D equipment is necessary prior to application of color Doppler. This topic summarizes a stepwise approach to the ultrasound anatomy of the fetal heart.

2019年2月16日 · In this chapter, we review normal fetal cardiovascular anatomy and physiology, recommended approaches for prenatal cardiac screening and detailed evaluation, ultrasound findings associated with common types of CHD, and …

2023年6月2日 · Effective fetal cardiac screening should maximize detection of structural anomalies and (according to available expertise and resources) abnormalities of function and rhythm, as part of routine prenatal care.

Ultrasound image shows the RVOT, the pulmonary trunk and bifurcation into the right and left pulmonary arteries. Image courtesy of Dr. Gunjan Puri, India. These 2 sonographic images of the fetal heart show the Left ventricular outflow tract as it leaves the fetal left ventricle . LV= left ventricle; RV= right ventricle.

2023年5月22日 · This routine anatomy ultrasound is performed between 18 to 22 weeks in every pregnancy to assess fetal anatomy, screen for anomalies, evaluate the placental location and maternal pelvic anatomy, and estimate gestational age (if not performed with an earlier scan).

Our study adds clear and detailed images of normal fetal hearts that have been dissected according to the standard fetal echocardiographic examination, extending the anatomic-echocardiographic correlations that underscored the development of fetal cardiology as …

2019年7月7日 · Most CHDs (>90% of cases) occur in fetuses with no history or known risk factor, and thus prenatal ultrasound (US) screening programs are essential for their diagnosis.

Ultrasound examination of the fetal heart is considered to be the most important and difficult part of a fetal anatomy analysis. The study of fetal heart can be obtained by two types of exam: screening ultrasound and diagnostic echocardiography.

2013 ISUOG Practice Guidelines (updated): sonographic screening examination of the fetal heart. Ultrasound Obstet Gynecol 2013; 41: 348–359. The ductus arteriosus is a small communication between the pulmonary artery and the aorta in fetal circulation. It arises from the most anterior chamber and has a “hockey stick” shape.
