title: Cardiac tamponade: new technology masking an old nemesis.
abstract: A 16-year-old male patient underwent bilateral pulmonary embolectomy complicated by reperfusion injury and acute respiratory distress syndrome requiring venovenous extracorporeal membrane oxygenation support using a bicaval double-lumen catheter. A unique hemodynamic profile developed consistent with tamponade but without an associated decrease in venovenous extracorporeal membrane oxygenation pump flow, improved venovenous extracorporeal membrane oxygenation circuit preload, and decreased recirculation. The use of newer bicaval double-lumen catheters can result in old problems presenting in new ways and require clinicians to be ever vigilant.
