Chronic Total Occlusion Revascularization Retrograde Approach
Chronic Total Occlusion Revascularization Retrograde Approach
Prospective registry data have demonstrated that successful PCI of a CTO lesion is associated with better symptomatic outcome, a reduced need for CABG, a lower rate of major adverse cardiac events at 12 months and improved survival when compared with unsuccessful attempts. Proposed contributors to improved survival include improved LV function, reduction in risk of ischemia-related malignant arrhythmias and better tolerance of contralateral coronary occlusion. These will be reviewed below.
