Objective: To report the antenatal detection rate in a consecutive series of l iveborn infants with atrioventricular septal defect (AVSD). Design: Review and a nalysis of referrals for detailed fetal echocardiography and postnatal diagnosis of AVSD. Setting: Tertiary referral centre for congenital heart disease centre with data prospectively collected between 1996 to 2001. Results: 92 consecutivel y liveborn infants with AVSDs were identified of which 27 (29%) were detected b y routine obstetric antenatal ultrasound. The antenatal diagnosis rate was worse for liveborn infants with trisomy 21(12 of 49(25%) v 15 of 43 (35%) chromosom ally normal children) and for infants with AVSD without other structural heart d isease (18 of 74 (24%) v 9 of 18 (50%) infants with associated structural hear t disease). Conclusion: Despite the potential ability of fetal ultrasound to det ect AVSDs, the antenatal diagnosis rate is poor. This is particularly true for i nfants with trisomy 21 and is of importance when counselling parents with an app arently normal fetal ultrasound scan.
