Effect on clinical outcome of pacing LV free wall scar in CRT. Kaplan-Meier estimates of the time to cardiovascular death or hospitalization for heart failure in patients with a LV free wall scar, grouped according to whether the LV lead was deployed over the scar or outside the scar. Hazard ratios and 95% confidence intervals derived from univariate Cox proportional hazards analyses are shown in parentheses. The right sided panels show representative short axis LGE-CMR slices of lead deployments on the scar and outside the scar. Adapted from Chalil S, et al. [95]
