If nasal suboptimal visualization is observed during an 11-week NT scan, it is important to consider further evaluation. While a normal heart rate and other parameters are reassuring, this finding may indicate a potential issue. The next step would be to consult with your healthcare provider or specialist who can provide guidance on additional tests or screenings that may be necessary. They will assess the overall risk factors and determine the best course of action for you and your baby's health. It is essential to address any concerns promptly to ensure appropriate care throughout your pregnancy.
