Usefulness of three vessel‐trachea view and parasagittal plan for prenatal diagnosis of interrupted aortic arch

Abstract

AbstractBackgroundInterrupted aortic arch (IAA) is a rare congenital heart disease characterized by loss of continuity between the ascending and the descending aorta. Prenatal diagnosis of IAA by echocardiography is challenging but nonetheless can be accomplished via a systematization of cardiac fetal evaluation.Case PresentationWe report a case of fetal IAA type A prenatally diagnosed through two‐dimensional echocardiography using both a three vessel‐trachea view and a sagittal view.ConclusionPrenatal counseling regarding the diagnosis and prognosis about this anomaly is still challenging nowadays due to associated anomalies/chromosomal abnormalities who may impact the prognosis. Fetal autopsy in all cases of pregnancy termination after abnormal ultrasound findings is important in order to make a full diagnosis and characterize the anomaly.
