{Abstract}: <B>BACKGROUND: </B>Several publications have considered results of percutaneous angioplasty for aortic recoarctation, but none focused on procedures performed in children aged<1 year.<BR><B>OBJECTIVE: </B>To describe the immediate and midterm results of balloon angioplasty for recoarctation before the age of 1 year, and to define the factors that might influence outcome.<BR><B>METHODS: </B>We retrospectively reviewed data from 20 consecutive children undergoing percutaneous dilatation for aortic recoarctation before the age of 1 year in the University Hospitals of Tours and Nantes.<BR><B>RESULTS: </B>In all patients except one, dilatation improved the median recoarctation diameter Z-score from -5.5 (range -10.6 to -2.5) to -2.8 (range -4.3 to 0.7) (P<0.001), and reduced the median peak systolic gradient from 33mmHg (range 20 to 60mmHg) to 21mmHg (range 6 to 50mmHg) (P<0.001). There was no procedure-induced mortality and no acute intimal flap or long-term aneurysm. Three patients experienced a transient femoral artery thrombosis, one of whom had a transient ischemic stroke. Eight children (40%) needed reintervention for further recoarctation (new surgery [n=4] or new dilatation [n=4]). A smaller balloon size was significantly associated with the risk of reintervention: balloon to recoarctation diameter ratio 2.0 (range 1.3 to 3.3) vs. 2.7 (range 2.1 to 4.5) (P=0.05); balloon to descending aorta ratio 0.8 (range 0.7 to 1.2) vs. 1.0 (range 0.9 to 1.3) (P<0.05).<BR><B>CONCLUSIONS: </B>In this study, percutaneous balloon angioplasty for recoarctation in young infants aged<1 year improved aortic isthmus diameter with a low incidence of adverse event. However, the rate of further intervention is high, and is associated with a smaller balloon size.
