Abstract：
:Balloon angioplasty for native coarctation of the aorta in infants and children is gaining acceptance as an alternative to surgery in discrete membranous obstruction. The aim of this study was to assess the immediate and intermediate-term effectiveness and safety of balloon angioplasty in infants and children with discrete membranous obstruction and mild complex arch anomalies. We performed a retrospective study evaluating the immediate and intermediate-term results of balloon angioplasty in 46 consecutive patients with native coarctation of the aorta done between March 1998 and June 2003. Isolated discrete fibromembranous obstruction occurred in 32 patients, and 14 patients had mild complex arch anomalies. Follow-up was obtained in 40 patients. There was no early mortality. The procedure was initially successful in 43 patients (93%). There were three immediate failures. Of the 40 patients who were followed, 32 (80%) had maintained a cuff pressure gradient of 20 mmHg across the dilated area. Four patients developed restenosis, which was successfully treated by repeated balloon angioplasty. The other four patients continued to have mild gradient (20-22 mmHg) with systolic hypertension and without angiographic evidence of restenosis but with isthmus hypoplasia; they received atenolol and captopril. Serial echocardiographic measurement of left ventricular dimension and function revealed significant improvement after balloon angioplasty of aortic coarctation in patients with the echocardiographic picture of hypertensive cardiomyopathy. Balloon angioplasty may be considered as a tool in the armamentarium of management of aortic coarctation in different anatomic variants, taking into consideration the clinical presentation and patient age.
