Retrograde Techniques and the Impact of Operator Volume on Percutaneous Intervention for Coronary Chronic Total Occlusions

, multioperator observational experience of 636 consecutive patients having CTO PCI to determine the impact of operator experience and advanced techniques on program development . Limitations of this analysis include limited centers and operators contributing to the series and potential broad extrapolation to other programs/operators. The observations from this series were that (1) extrapolation and iteration of advanced CTO PCI techniques can be transferred for highly successful programs in a variety of clinical care settings, (2) CTO specific volume/experience is the key determinant for escalation of procedural success rates, (3) advanced techniques are required to execute an “all comers” strategy to treat patients with appropriate clinical indications irrespective of anatomic complexity.
