Dr. Chen’s paper1 demonstrates the superior femoral artery flow and pressure characteristics of Bi-Flow through a comparison with a standard femoral arterial cannula. It shows how Bi-Flow was simple to insert and position, and how the bidirectional cannula can supply adequate blood flow to the lower limb at full CPB support.
This is a well-designed and well-performed experimental study that clearly demonstrates the benefits of this bidirectional femoral cannula. This study suggests that Bi-Flow may have significant benefits in both minimally invasive valve replacement and other cardiac surgical patients undergoing peripheral cannulation.
