Background: Balloon atrial septostomy is an emergent procedure in pediatric cardiology. Nowadays, most patients in need of the procedure have acceptable outcomes after surgical repair. Thus, it is important to perform this procedure as safe as possible. By performing early arterial switch operation and prostaglandin infusion, the rate of balloon atrial septostomy has markedly decreased. However, not all centers performing early arterial switch repairs have abandoned atrial septostomy, even in patients who respond favorably to prostaglandin infusion.
Case presentation: In total, eight 1- to 15-day old term neonates admitted in Shahid Rajaee Heart Center in Tehran, Iran from October 2009 to February 2011, with congenital heart diseases were scheduled for balloon atrial septostomy. In six cases the procedure was done exclusively under echocardiographic guidance and in two cases with the help of fluoroscopy. Success was defined as the creation of an atrial septal defect with a diameter equal to or more than 5 mm and ample mobility of its margins.
Results: Male sex was predominant (87%) and the mean age of the neonates was six days. The diagnosis in all cases was simple transposition of great arteries. The procedure was successful in all patients with any cardiovascular complication.
Conclusion: Balloon atrial septostomy is an emergent procedure that can be done safely and effectively under echocardiographic guidance. According to the feasibility of this technique it could be performed fast, safe and effective at bedside, avoiding patient transportation to hemodynamic laboratory or referral center.
