The median (range) procedural age was 44 days (17\u221293 days) and weight 1344\u2009g (855\u20133900\u2009g). Successful implantation with microcatheter deployment occurred in 12\/13 infants. In 11 cases, the 8\u2009mm Azure device was deployed. The ratio of the unconstrained device to the minimal PDA diameter ranged from 2:1 to 4:1 and decreased with experience. The minimal ductal length for deployment was 9.0\u2009mm (lateral angiography). Mean (range) follow\u2010up was 5.8 months (1.5\u201315.7 months). Complete ductal occlusion prior to 6\u2010month follow\u2010up occurred in 11\/12 infants. No aortic obstruction, left pulmonary artery obstruction, or tricuspid valve injury was noted in follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The Azur Vascular Plug is a safe and effective option for PDA device occlusion in premature and low birth weight infants. The sizing limits in premature ducts are under evolution. The Azur device appears suitable for ducts with a minimal length of 9.0\u2009mm and, conservatively, a diameter up to 5.0\u2009mm.<\/jats:p>\n
