ABSTRACT
The spectrum of congenital heart disease (CHD) that can be encountered in the fetus is wide, with a significant number of very complex defects. The description of these defects can benefit from a sequential segmental analysis, which consists of a step-by-step procedure that defines the central cardiovascular connections, beginning from the venous pole to the arterial one. This is complemented with the assessment of the atrial and ventricular septation. Only in this way is it possible to understand and effectively describe the anatomy of complex fetal CHD. Hereafter, we describe this approach and the scanning planes needed to perform this assessment. Then, for each scanning plane normal vs non-normal aspect will be illustrated.
