Hello, My wife went for Anomaly/TIFFA scan at 18w 6d. During the investigation it was found that baby has CTEV in right foot and Echogenic intracardiac focus in left ventricle and during isolation it is below the baseline risk. Her gynaecologist has suggested for further investigation (Amniocentesis) because she thinks it might be because of chromosomal abnormalities. Her NT/NB scan was normal and dual marker test had low risk. But doctor also said that there is 0.5% chances of loss of pregnancy due to this test. What should I do?
