title: Assessment of bedside umbilical vein balloon septostomy using two-dimensional echocardiographic guidance in transposition of great arteries.
abstract: The effectiveness of "bedside" balloon atrial septostomy via the umbilical vein using 2-dimensional echocardiography was compared to the traditional femoral vein approach using fluoroscopy in a series of neonates with transposition of great arteries from March, 1984 to April, 1987. There were 7 neonates who had balloon septostomy performed at the "bedside" (Group I) compared to 13 who had the procedure performed in the catheterization laboratory (Group II). Group II consisted of 7 newborns who had elective femoral vein catheterization under fluoroscopy (Group IIA) and 6 who failed "bedside" umbilical vein balloon septostomy and subsequently had the femoral vein approach under fluoroscopy (Group IIB). Results showed that adequacy of balloon septostomy was not related to the approach used, with 4 of 7 in Group I and 9 of 13 in Group II with an adequate atrial tear and clinical response. The Delay time to septostomy (i.e. time elapsed from initial assessment to commencement of balloon septostomy) and Procedure time (i.e. time taken to complete the balloon septostomy) was significantly shorter for Group I (mean time = 0.7 hours and 0.26 hours respectively) compared with Group IIA (mean time = 2.6 hours and 1.8 hours) and Group IIB (mean time = 2.4 hours and 1.4 hours). Of note, there was no significant increase in Delay time between Group IIA and IIB.(ABSTRACT TRUNCATED AT 250 WORDS)
