✦ Synopsis

asymptomatic patients were identified with hypoplasia of the aortic isthmus at the time of cardiac catheterization for closure of a small patent ductus arteriosus. lsthmal diameters measured from lateral aortograms were 62 -t 11% of age-matched controls. All patients had a small communication occluded with a 12 mm devfce and remained asymptomatic at 6-30 months folfow up.

Residual shunting was demonstrated by color Doppler in 2 patients. No child has developed an arm-leg systolic blood pressure gradient or systemic hypertension. Following device placement, Doppler interrogation across the isthmus in 2 patients demonstrated a velocity shift of 2.1 m/s. Transcatheter occlusion of the patent ductus arteriosus associated with mild isthmal hypoplasia of the aortic arch appears safe and effective and does not result in a clinically significant impairment to isthmal flow in short-term follow-up.
