Figure 4 Representative recordings of left ventricular (LV) two-dimensional (top) and M-mode (bottom) echocardiography at three weeks after the treatments. Left ventricular remodeling was almost completely inhibited in a rat form naked plasmid hepatocyte growth factor (HGF) infusion with ultrasound-mediated microbubble destruction (US/MB) (HGF-US/MB) group, while the intraventricular septum was thinned and LV chamber was dilated in the other groups. Other abbreviations as in Figure 3.
