Diagnóstico ecográfico y manejo de la infección fetal por parvovirus B19

The results of B19V infections largely depend on the degree of the anaemia, the haemodynamic status of the foetus, and the risk of invasive procedures. Some parameters, such as the presence of tricuspid regurgitation, can be used to diagnose foetal anaemia and could therefore be useful as a tool to evaluate the use of invasive procedures to directly estimate the degree of foetal anaemia.
