PY - 2015 T2 - Fetology: Diagnosis and Management of the Fetal Patient, 2e AB - Key PointsVentricular septal defects are the most common congential cardiac malformations, and often occur as part of more complex abnormalities, such as tetralogy of Fallot or transposition.Prenatal diagnosis should be straightforward using a long axis view of the ventricles, followed by a short axis sweep from apex to base.Many isolated small VSDs, especially of the muscular type, will close spontanteously in utero, or in infancy.Significant VSDs that contribute to failure to thrive, or those associated with increased pulmonary vascular flow, should be surgically repaired by 6 months of age.Recent advances in minimally invasive transcatheter septal occlusion devices hold great promise as an alternative to open surgical repair with cardiopulmonary bypass.
