It is important to have a follow-up consultation with your healthcare provider to discuss the sonogram findings and any concerns you may have. They can provide you with a detailed explanation of the specific findings on the sonogram, including any potential issues with the development of the baby's heart. During the consultation, your healthcare provider may also recommend additional tests or monitoring to assess the baby's heart further and determine the appropriate course of action.
