Fetal echocardiography is an important imaging modality for screening fetuses with congenital heart disease.Not all cardiologists are familiar with this imaging . Obstetricians are also not well versed in these techniques.So, finally, it is left to few specialised radiologists to do this job. The issue here is they are less in number and the need for the experise is huge. Further , the fetal cardiac hemodynamics and anatomy are too complex to comprehend for a non cardiologist . So it is argued every clinical cardiologist to get trained in the basics of fetal echocardiography.
There are dedicated institutes and people who do this mode of imaging.
