Top: A single pseudo-long axis-plane (left) and three-plane view (right) with an injection catheter shown in green prior to labeled stem cell injection. The catheter is steerable and flexible to enable access to many portions of the left ventricular endocardial surface. Bottom: During injection of iron oxide-labeled stem cells the active catheter gain is no longer colored to enhance detection of hypointensities in the myocardium to document stem cell injection success.
