Figure 5 Catheter-based myocardial injections into ischemic swine left ventricle (LV). NOGATM 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.
