This is a training video about the first trimester fetal echocardiograpy. The compilation video consists of 31 short clips from 18 patients scanned at 11-13 weeks of pregnancy due to high risk for congenital heat disease (CHD). All presented cases had normal heart anatomy, which was confirmed by 20 week fetal echocardiography.

The indications for early pregnancy fetal echocardiography include:

• Increased nuchal translucency thickness
• Tricuspid regurgitation
• Reversed a-wave in ductus venosus
• Extracardiac anomaly, such as exomphalos
• Previous pregnancy complicated by fetal CHD

All the scans were performed using a Voluson 730 ultrasound scanner. In the video every clip is played twice. In order to provide the viewer with the real experience of heart scanning the clips are not annotated.  For an annotated training video of fetal echocardiography please refer to our post ‘Fetal echocardiography at 11-13 weeks of pregnancy’.
