The first step of the fetal cardiac interrogation is to describe the arrangement and location of the heart in relation to the overall arrangement of the fetus. In this regard, there are four basic patterns, namely, the usual arrangement, often described as “situs solitus,” its mirror image, or “situs inversus,” and the arrangements of ...
