Fetal Echocardiography Practice Test

Limitation: prenatal coronary origin assessment is technically challenging and typically limited to standard views rather than a detailed coronary map. The coronary origins in the fetus are extremely small and oriented in ways that make consistent visualization difficult. Fetal motion, limited acoustic windows, and the need to image through maternal tissue mean that clinicians can usually establish general cardiac anatomy and some major patterns, but mapping each coronary ostium and tracing its exact course is not reliably achievable before birth. Because of these constraints, prenatal imaging is unlikely to provide a complete, detailed map of coronary anatomy. The other statements overstate what prenatal evaluation can deliver: it does not routinely yield a full surgical plan, it does not guarantee detection of every coronary anomaly, and it remains a relevant part of fetal evaluation rather than unnecessary.
