Figure 5 Catheter-based myocardial injections into ischemic swine left ventricle (LV). NOGA^TM electrical (maximum unipolar voltage) and mechanical (linear log shortening) maps of the swine LV are shown. Note area of ischemia in the lateral wall—normal electrical activity (blue/green) coupled with poor mechanical function (red). Images A and B represent anteroposterior projections demonstrating six injection sites (red hexagons) in an area of normal myocardial (apex) remote from the ischemic zone. Images C and D depict LAO projections of indicated injection sites in the ischemic lateral LV free wall. LA = left arm; RA = right arm.
