Chronic Total Occlusion (CTO) Live is an intensive 1 day scientific program held in the beginning of January every year. Comprehensive and interactive live case demonstrations as well as advanced operator techniques with new devices in this program allow interventionalists to translate the new technology into daily interventional practice to improve patient care. The 1st CTO Live was held at the Asan Medical Center in January 2007 in close collaboration with the Toyohashi Heart Center (Japan) by inviting 4 Japanese operators from this group.
