Fibrosis deposition in healthy and diseased tissue. Representative images of fibrotic (blue) and nonfibrotic tissue (red) in (A) control left ventricle (LV) tissue and diseased tissues of the (B) LV and the (C) left atrium (LA) show variability in fibrotic deposition in the diseased tissue and not in the control tissue. (D) Graph shows mean ± 95% confidence interval of percentage fibrotic tissue with significantly less fibrotic deposition in the control tissue (n = 10) compared with the left atrium (P = 0.0034; n = 17) but not the left ventricle (P = not significant; n=11).
