A migrated dual-lumen cannula can be corrected under imaging without stopping ECMO flow; a femoral wire under fluoroscopy is an option when the tip is in the right ventricle.

Hepatic vein case: repositioning under echocardiographic guidance without a guidewire. Right ventricle case: repositioning using a guidewire from the femoral vein under fluoroscopy.
Two cases, single centre; abstract only read; presentation of each case not described in the abstract.
Both cannulas repositioned; the right ventricle case without antegrade wire placement into the cannula, without discontinuation of ECMO, and without bleeding. Authors state malposition can cause inadequate ECMO flow, hypoxia and structural injury.
Two adults on venovenous ECMO with a jugular dual-lumen bicaval cannula that migrated — one into a hepatic vein, one into the right ventricle.
