AVS is the area between the insertion of the mitral valve and the tricuspid valve leaflets to the ventricular septum. In normal fetuses, the tricuspid valve has an apical displacement relative to the mitral valve. We aimed to create a nomogram of its normal dimensions, beginning in the 11th gestational week.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Measurement of the length of the AVS was performed during ultrasonographic fetal echocardiography, in the four\u2010chamber view from 11 to 34 gestational weeks in otherwise normal pregnancies. In addition, standard fetal biometry was measured. Linear regression analysis was used to evaluate the correlation between variables.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Two hundred and ninety\u2010two examinations of normal fetuses were included.

AVS length was also proportional to inter\u2010ventricular septum (IVS) length with increasing gestational age (<jats:italic>r<\/jats:italic><jats:sup>2<\/jats:sup> = 0.882, \u03b2 = 0.94, <jats:italic>P<\/jats:italic> &lt; 0.001).
