Our data could be used for assessing the feasibility of screening fetal cardiac valves during the routine echo. This will aid in early diagnosis of congenital heart diseases leading to better pregnancy outcomes. The assessment of fetal cardiac valves during routine fetal echocardiography is of paramount importance due to the limitations and subjectivity associated with current evaluation methods. Traditional methods rely on two-dimensional echocardiography (2DE), which may not provide a comprehensive and accurate representation of fetal cardiac structures. The feasibility to evaluate fetal cardiac valves becomes crucial as 2DE can be limited in depicting subtle malformations, and there is a need for a more objective and advanced approach. Screening of fetal cardiac valves requires skill, experience, equipment, time and appropriate planes of view. We will study these factors and assess the feasibility of screening of fetal cardiac valves to include it during our routine fetal echo. Given the potential impact on prenatal diagnosis and patient care, incorporating advanced imaging techniques for fetal cardiac assessment aligns with the need for more accurate and objective methodologies. Establishing reference ranges for fetal cardiac valve diameters could significantly enhance the precision of routine evaluations, providing clinicians with a standardized and

reliable tool. This research is justified by the necessity to overcome the limitations of current practices, ensuring better-informed decisions, and ultimately improving outcomes for both mothers and fetuses.
