Interventional re-opening of a PDA for reverse potts shunt circulation after ADO I implantation in a child

We report interventional re-opening of a PDA for reverse Potts shunt circulation 12 months after closure in a 3.8 year old child, suffering from right ventricular (RV) failure due to suprasystemic pulmonary artery hypertension (PAH) after ADO I implantation. After ex vivo simulation, perforation through the mesh of the ADO I with the use of transseptal needle, wire looping (AO-PA), balloon dilatation, stent implantation (Palmaz 6 mm) and post dilatation, a reverse Pott-shunt circulation was established. A follow-up period of 11 months was achieved with preserved RV function and reverse Pott shunt circulation maintained a post ductal saturation of 94-88%. © 2016 Wiley Periodicals, Inc.
