Median birthweight and procedural weight were 890\u2009g (range: 490\u20133,250) and 2.8\u2009kg (range: 1.2\u20134.0), respectively. Median follow\u2010up was 0.7\u2009years (range: 2\u2009days\u20137\u2009years). Thirty\u2010eight patients had post\u2010procedure echocardiograms assessing LPA\/aortic obstruction. Of those, 17 had LPA flow acceleration\/stenosis (\u22651.5\u2009m\/s), which improved or resolved in all patients with available follow\u2010up; 3 developed mild coarctation (&gt;2\u2009m\/s), which improved in the two with more than short\u2010term follow\u2010up; 4 developed mild flow acceleration (1.5\u20132\u2009m\/s) in the descending aorta, which resolved in three and increased in one (2.4\u2009m\/s). Flow acceleration in the LPA was associated with younger procedural age, larger PDA minimal diameter, and placement of a device other than the AVPII.
