Bicaval dual-lumen cannula for venovenous extracorporeal membrane oxygenation (VV ECMO; Avalon Elite®) and corresponding echocardiographic views. This picture depicts a bicaval dual-lumen cannula, inserted via the internal jugular vein. The drainage holes are located in the superior vena cava and inferior vena cava (IVC), and the reinjection hole is facing the tricuspid valve (TV). a Mid-esophageal bicaval view showing the cannula within the right atrium (RA) (transesophageal echocardiography). b Transthoracic subcostal view showing the cannula in the RA; the tip of the cannula is located in the IVC. The reinjection hole is visible, oriented towards the tricuspid valve. RV, right ventricle
