B-type brain natriuretic peptide as marker of hemodynamic overload of the patent ductus arteriosus in the preterm infant Péptido natriurético cerebral tipo B como marcador de sobrecarga hemodinámica del conducto arterioso permeable en el recién nacido prematuro

The left lung perfusion may be compromised after percutaneous closure of patent ductus arteriosus with the Amplatzer Duct Occluder. The increased flow velocity in the origin of the left pulmonary artery can be a poor indicator of reduction in pulmonary perfusion and can occur in the absence of protrusion of the device.

The Amplatzer Duct Occluder II in this series was effective in 89% of the patients at 24hs after the procedure and 100% follow-up. The implantation was safe and no major complications were observed. The occlusion rate is comparable to those reported for the Amplatzer Duct Occluder I.
