Hello! Girls, at 19 weeks when I went for an ultrasound they noted a hyperechoic focus in the right ventricle of the fetal heart. They also wrote pyelectasis of the fetal kidneys. Has anyone encountered this diagnosis? Isn't it dangerous? When I went to the geneticist they didn't really say anything. They told me to come with the results of the 3rd ultrasound. (I'm going in 2 weeks) PLEASE! If you know, could you tell me? Thank you in advance!!! Wishing you all health and safety!!!
