Segmental scar and circumferential strain by CMR versus VVI echocardiography. The distribution of myocardial fibrosis by quartile of Ecc as assessed with (A) CMR (all segments) or (B) VVI echocardiography (mid-cavity segments only) is shown. A) No segments with Ecc by CMR in the fourth (most negative) quartile had myocardial scar. Myocardial scar was most common in the two lowest (most dysfunctional) Ecc quartiles. B) Scar was also unlikely in segments falling into the fourth quartile of Ecc as assessed by echo VVI and was distributed in the lower three echo Ecc quartiles. 1^st quartile = least negative Ecc (most dysfunctional); 4^th quartile = most negative Ecc.
