Fig. 2From: Left ventricular geometry predicts ventricular tachyarrhythmia in patients with left ventricular systolic dysfunction: a comprehensive cardiovascular magnetic resonance studyRepresentative ischemic cardiomyopathy cases with and without increased sphericity index. Example cases (a) 68Â year-old man with prior inferior myocardial infarction who received appropriate ICD therapy. Larger sphericity index of 0.73 as well as severe LV dysfunction (LVEFÂ =Â 18%) was documented although LGE-CMR image showed only a small area of focal subendocardial inferior wall enhancement. b 61Â year-old man with an extensive anteroseptal myocardial infarction who did not receive ICD therapy. Sphericity index was 0.48, however there is marked dyskinesis with LVEF 21% on the LV apex and transmural LGE were observedBack to article page
