- Patients will need to be admitted to the hospital about a day before thet receive the study drug (bone marrow cells). During this time patients will have a procedure called cardiac catheterization. The study doctor will make a small puncture in the groin after the area is numbed with a local anesthetic (similar to Novocaine use by a dentist). Two thin catheters (tubes) will be placed in the groin area, one in a vein and one in an artery (large blood vessels). Blood thinners will be given during this procedure to help prevent blood clots. A series of thinner tubes (catheters) will then be inserted into the first tubes and will be carefully pushed up into the heart chambers. These catheters will be used to produce a 3-dimensional colored map (NOGA) that shows where the heart has been damaged. When mapping is complete, this catheter will be taken out and a new device with a needle in the tip will be run through the tubes. Using the map of your heart, the doctor will inject NX CP105 into parts of the heart that look like they were damaged.
