Kaplan–Meier curves for comparison of appropriate implanted cardioverter-defibrillator (ICD) shock or death between 2 CMR contouring methods. Left ventricular (LV) ejection fraction (LVEF) is displayed in quartiles, measured by a excluding and b including the trabeculae and papillary muscles (TPM) in the total LV mass. LVEF excluding TPM: median = 27.9 (25th percentile = 21.9, 75th percentile = 37.7); LVEF including TPM median = 32.9 (25th percentile = 25.2, 75th percentile = 44.3). Survival or event-free times were significantly longer for higher LVEF whether measured by excluding (log rank test, p for trend = 0.004) or including TPM (log rank test, p for trend = 0.019)
