Despite major advances in coronary intervention, the recanalization tragic hero examples in literature of a chronic total occlusion (CTO) remains a challenge for many interventional cardiologists. Complex anatomy and lesion characteristics demand a special set of skills for procedural success. Provided patient selection is appropriate, CTO intervention can confer a variety of benefits including relief of angina, improvement in left ventricular function and reduction in ischemic burden. Procedural success is enhanced by adequate training of staff, by quality control and availability of equipment. RETRO CTO Vienna is a unique opportunity to meet world leaders in CTO revascularizations paper writers during the performance of live cases, during lectures and interactive sessions on recorded cases, all in the fantastic city of Vienna, and the friendly venue of the Vienna General Hospital.
