Insertion of the Avalon Cannula for Venovenous Extracorporeal Membrane Oxygenation in a Patient with an Implanted ASD Occlusion Device

Use of the Avalon Elite bicaval dual lumen catheter (Maquet Cardiopulmonary AG, Rastatt, Germany) can be effective in patients requiring venovenous extracorporeal membrane oxygenation (VV-ECMO) for adult respiratory distress syndrome (ARDS). Proper placement of the cannula is important in providing adequate therapy and avoiding life-threatening complications. We report a case of successful cannulation in a patient with an implanted atrial septal defect (ASD) occlusion device who developed severe <br />refractory ARDS.
