Placement of a bicaval dual‐lumen ( BCDL ) catheter demands sophisticated visualization in patients to assure proper positioning in order to administer single‐site venovenous extracorporeal membrane oxygenation ( VV ECMO ). Large animal models are needed and thus appropriate procedures to assure anatomic and functional cannula placement would assist in experimental design and procedures. This report describes the use of agitated blood and saline transthoracic contrast echocardiography to confirm appropriate placement and function of the BCDL catheter in a swine model of VV ECMO . Five consecutive common crossbred piglets had confirmation using this technique with assurances of cannulation while not significantly altering experimental time and procedures. Researchers studying VV ECMO in large animal models may want to consider this method of confirmation of BCDL catheter placement.
