Figure 5 Echocardiographic Assessment
Echocardiographic assessment of the polyester urethane urea patch, infarction control, and normal control groups during the study period. End-diastolic area is shown in (A), and % fractional area change in (B). End-diastolic area and % fractional area change in the normal control group were significantly different than those in the patch and infarction control groups (p < 0.05) at each time point and did not significantly vary during follow-up. *p < 0.05 between groups; 
p < 0.05 versus just before implantation (pre) within group. 4w = 4 weeks after implantation; 8w = 8 weeks after implantation.
