Title: PP-245 Atrioventricular Septal Defect Diagnosed By Fetal Ultrasonography
Abstract: AimThe term atrioventricular septal defect (AVSD) or atrioventricular canal defect (AVCD) or endocardial cushion defect is characterized by absence or deficiency of atrioventricular septum of the heart. Clinical presentation and outcome are related to type of anatomic variability. Herein, we presented a case with AVSD, diagnosed by fetal ultrasonography (FUS).CaseA 41-year-old pregnant having 3 healthy children and 4th current pregnancy (19th gestational week) underwent detailed FUS for detecting possible developmental anomalies.ResultsFUS measurements were concordant with fetal gestational age. During cardiac examination we realized that atrioventricular septum was absent. The defect of atrial septum was in the anterior part(septum primum) and the defect of ventricular septum was in membranous part. There was only a single atrioventricular valve in place of two atrioventricular valve. Other than AVSD remaining cardiac structures and other organ-systems were anatomically normal and concordant with fetal developmental age. Because of AVSD amniosynthesis was performed and the result was trisomy 21 (Down syndrome). The pregnancy was terminated.DiscussionAVSD occurs in 2% of all congenital heart diseases and is more prevalent in patients with Down syndrome. Forty-five percent of children with Down syndrome have congenital heart disease, and 35-40 % of defects are forms of AVSD. In addition, one-third of all children born with AVSD also have Down syndrome. FUS is an easily accessible, inexpensive, nonionizing and the first diagnostic tool in such cases.ConclusionDiagnosis of AVSD in FUS is relatively easy but requires high experience.
