Ultrasound images of anomalies of the fetal heart:Normal four chamber view of the fetal heart:
Fetal echocardiography:
The above fetal echocardiography images show the normal fetal heart. Note the foramen ovale opening to the left atrium. LA= left atrium RA= right atrium; LV= Left ventricle; RV= Right ventricle.
Congenital anomalies of the fetal heart:
AVSD (atrioventricular septal defect):
A large atrial septal defect (ASD) is also seen in these ultrasound images.
AVSD is also known as endocardial cushion defect or AV canal defect. It is caused by poor or faulty development of the endocardial cushion. These fetuses usually have other associated cardiac anomalies. The above images reveal large defects in the atrial and ventricular septae with a single large Atrio-ventricular valve replacing the mitral and tricuspid valves. In fact the the ASD is so large, that it appears like a single large atrium. Images courtesy of Dr. Latha Natrajan, Bangalore, India. Reference: http://www.centrus.com.br/DiplomaFMF/SeriesFMF/18-23-weeks/chapter-04/heart/heartfmf-complete.html (free article with video clips and images)... rated (by us) as excellent. Fetal pericardial mass:Sonography of this 36 weeks old fetus revealed a large echogenic mass in close relation to the exterior of the fetal left ventricle, within the pericardial cavity.. A small pericardial effusion is also present. These ultrasound images suggest a solid, non-calcific mass of the pericardium. Possibilities include rhabdomyoma, teratoma and hemangioma. Rhabdomyomas are the commonest pericardial tumours and account for almost 75 % of cardiac masses. Teratomas can be either cystic or solid.

DORV (Double Outlet Right Ventricle):
This is a 4.2 MB video file in GIF format. It might take some time to download. The aorta and the pulmonary trunk are seen mostly arising from the right ventricle. This condition is difficult to distinguish from Fallot's tetralogy and Transposition of the great arteries (TGA). Video courtesy of Dr. Latha Natrajan, Bangalore, India. Here is the link to the same video clip (DORV) in real media (you'll need "real player" to play this): Try www.real.com to get the free "real player".

Sonography of fetal VSD: These ultrasound and color Doppler images show a VSD in the muscular part of the ventricular septum of the fetal heart. This type of VSD is called a trabecular ventricular septal defect. Flow is seen across the defect in the septum, from left ventricle to the right (color Doppler images). There are 4 types of VSD: a) perimebranous b) inlet c) trabecular d) outlet. This classification is based on the location of the defect. Images courtesy of Gunjan Puri, MD, India. See this link for more: Fetal echocardiography (free article and images). Rated excellent..
Some more Color Doppler/ Ultrasound image of Fetal VSD:This 3rd trimester fetus showed a small Ventricular Septal Defect (VSD) (see arrow heads), near the cardiac apex. Flow across the septum is seen in red hue on Color Doppler imaging (arrowheads). Fetal echocardiography images of VSD are courtesy of Gunjan Puri, MD, India. Ectopia cordis:Case-1: Case-2: The above 3 B-mode ultrasound images show the fetal heart lying partially outside the thoracic cage (case-2) or completely outside the thorax (case-1). I have added a video (ultrasound) clip of case-1 at my blog: See: http://cochinblogs.blogspot.com/2009/09/another-case-of-ectopia-cordis.html Case 1 does resemble an umbilical hernia from the ultrasound images on top. However the Color Doppler image of case 1 clinches the diagnosis of ectopia cordis. This was a early 2nd trimester fetus. Case-1 ultrasound images are courtesy of Dr. Dilraj Gandhi, India. This fetus also shows increased Nuchal thickness. Case-2 shows ectopia cordis with heart partially ouside the thoracic cage. The ultrasound video of this case can be viewed at this link: http://cochinblogs.blogspot.com/2009/04/ultrasound-video-of-ectopia-cordis.html This ultrasound image was taken by Joe Antony, MD, India.
