(A) Representative post-contrast AIR cardiac T 1 maps of a dog with AF duration = 15.2 months: (left) basal (T1 = 737 ms), (middle), mid-ventricular (T1 = 708 ms), and (right) apical (T1 = 740 ms) planes, with mean ECV = 26%. (B) Histologic evaluation of Masson's trichrome staining of LV tissue (midwall) samples from the antero-lateral LV in different dogs sacrificed at different durations of AF: (left) baseline and (right) 22.6 months. All specimens displayed with 10× magnification.
