Does the presence of CTO predict ventricular arrhythmias and long-term mortality in patients with ischemic heart disease receiving ICDs for primary prevention?
In patients with ischemic heart disease and primary prevention ICDs, the presence of a chronic total occlusion predicts ventricular arrhythmias and increased long-term mortality.
In patients with ischemic heart disease receiving ICDs for primary prevention of SCD, CTO is an independent predictor for the occurrence of ventricular arrhythmias and has an adverse impact on long-term mortality.
