This happened with my first but it was a marker in his brain , they said they didn’t even want to tell us about it bc it stresses Moms out more then it should but legally they have to tell you if they find one , we couldn’t afford a follow up anatomy scan but my midwife sounded confident that it was fine , he came out a healthy baby. I wouldn’t stress about it

In terms of heart defects, he states between the two atria (producing an ejection systolic murmur) being most common ('usually') but note the most common is an AVSD, which produces a holosystolic of course, along with VSDs Prevalence AVSD: 29% VSD: 21.5% ASD: 19.9% (EJ murmur) So you will most likely hear a holosystolic murmur source for chd prevalence ; Benhaourech, CHD & down syndrome
