Y1 - 2015 N1 - T2 - Fetology: Diagnosis and Management of the Fetal Patient, 2e AB - Key PointsPrenatal diagnosis of aortic stenosis is unreliable.Aortic stenosis should be suspected whenever there is asymmetry of the cardiac ventricles including either left ventricular enlargement or left ventricular hypoplasia.Evaluation with serial fetal echocardiography should include consideration of coarctation of the aorta and the possibility of progression to hypoplastic left heart syndrome.In utero balloon dilation of the aortic valve has been described but is of questionable value.While pediatric balloon valvuloplasty is very successful, the high rate of reintervention required suggests that definitive surgical repair leads to best long-term outcome.
